Rational

The Rational iCombi Pro 6-1/1 is a six-grid electric combination oven capable of convection, steam, and combination cooking within a single unit. It accommodates six full-size 1/1 GN pans simultaneously — one per shelf — making it a genuinely versatile piece of cooking equipment in a relatively compact footprint. This is a considered capital investment, not an incremental upgrade, and it works hardest when it is correctly matched to the kitchen and service model it is being asked to support.

In a working kitchen, the iCombi Pro is built for the consistency that busy service demands. Rational's iDensity Control system continuously manages airflow and moisture throughout each cook cycle, which supports even results across a full load — particularly valuable when running the same product repeatedly through a lunch or dinner push. Recovery between loads is efficient, and the ability to handle varied loads without constant manual intervention gives the kitchen meaningful flexibility when producing a mixed menu to order.

From a day-to-day operational perspective, several features translate into practical advantages:

• iCooking Suite guides cooking toward a defined end result, reducing dependence on individual operator skill
• iProduction Manager sequences multiple dishes to help maintain smooth, coordinated output during multi-course service
• Automated cleaning completes in around 12 minutes, keeping downtime between shifts to a minimum
• Integrated Wi-Fi connects to the ConnectedCooking platform for remote monitoring and recipe management across sites
• Improved energy and water efficiency compared to earlier Rational generations helps manage running costs over time

Installation requires a three-phase electrical supply — not a standard single-phase connection — and this should be confirmed with a qualified electrician before ordering. Ventilation is essential and will typically mean a canopy extraction system or a Rational-approved ventilation hood. Plumbing for the steam system and a suitable drainage point also need to be in place before installation day. Allow adequate clearance for the door swing and ongoing servicing access. These are not afterthoughts; addressing them at the planning stage avoids delays and additional cost on the day.

This format is well suited to smaller restaurants, cafés, pub kitchens, hotel operations, and contract catering sites where output is moderate, space is a real consideration, and a varied menu makes single-function cooking equipment a limiting choice. It performs particularly well in kitchens where consistent results across different shifts and different operators genuinely matters. For larger banqueting operations or high-throughput production kitchens, a higher-capacity model is likely the more practical fit.

Whether this configuration is the right choice depends on your service model, menu, existing infrastructure, and how it sits within your broader kitchen workflow. If it would help to talk it through before you commit, we are here to do that.

The Rational iCombi Pro 10-1/1 is a ten-rack electric combination oven designed for professional kitchens that need reliable, consistent output across a full service. It combines convection, steam, and combination cooking modes in a single cabinet, allowing roasting, baking, steaming, regeneration, and finishing to be handled without separate pieces of equipment for each process.

Where this oven justifies its place is during sustained, high-volume service. The iDensity Control system manages airflow, humidity, and heat distribution across the full cabinet, so a mixed load — different products, different sizes, loaded at different times — holds quality across every item. Recovery after door opening is handled well, which matters when the oven is being accessed continuously throughout service and any delay has a knock-on effect down the line.

Several of its features translate into clear operational advantages:

• iCooking Suite automates cooking processes, supporting consistency across shifts regardless of individual chef experience
• iProduction Manager sequences multi-item loads and reduces manual interventions during service
• Automated cleaning completes quickly on the fast cycle, minimising downtime between services
• Integrated WiFi connects to Rational's ConnectedCooking platform for remote monitoring and centralised recipe management
• Energy and water consumption are meaningfully reduced compared to earlier-generation models, with a measurable effect on running costs over time

This is an electric unit requiring a three-phase power supply — single-phase connection is not an option, and confirming the electrical infrastructure before purchase is essential. The unit needs adequate clearance on all sides for ventilation and door swing, and given its weight, floor load capacity is worth checking during kitchen planning. If stacking with a base unit or a second oven is intended, this should be factored in at the specification stage rather than addressed later.

The iCombi Pro 10-1/1 is well suited to hotel kitchens, contract catering operations, healthcare and institutional catering, and larger restaurant kitchens producing consistent volume across multiple services. The investment is most justified where the ten-rack capacity and the full feature set are genuinely being put to work. For lower-volume operations, a six-rack variant is likely to represent better value. For very high-volume or multi-site operations, larger-format models within the Rational range may be worth considering.

If you would like to work through whether this configuration suits your kitchen before committing, our team is happy to talk it through with you.

The Rational iCombi Pro 6-2/1 is a full-size electric combination oven designed for professional kitchens where consistent output, cook-to-cook repeatability, and reliability across a long service are fundamental requirements. It accepts full 2/1 GN pans — two per level in landscape orientation — making it one of the higher-capacity single units in the iCombi Pro range. At this price point, it is a considered capital purchase and worth understanding in detail before committing.

In service, the iCombi Pro builds its reputation through repeatable results under sustained load. The onboard cooking intelligence monitors conditions inside the cabinet continuously, compensating automatically for variations in load size and food type. When your team is pushing mixed dishes through a busy service, the oven adjusts rather than asking for manual correction. Recovery between loads is strong, and transitions between steam, convection, and combination modes are managed by the unit itself. For kitchens running back-to-back covers, that level of consistency measurably reduces pressure at the pass.

From a day-to-day operational standpoint, the iCombi Pro addresses several practical demands at once:

• Intelligent production planning sequences mixed loads without manual guesswork
• Automated cleaning cycles minimise downtime between services
• Consistent cabinet-wide results reduce the need for individual dish monitoring
• Integrated Connected Cooking supports remote monitoring and recipe management across multiple sites or units
• Efficient moisture management improves food quality and reduces energy draw compared with older combi technology

Installation planning is essential before this unit arrives on site. It is a substantial, high-power piece of equipment requiring a dedicated electrical supply, adequate ventilation provision, and clear access on all sides for safe operation and servicing. The 2/1 GN footprint is physically larger than a standard 1/1 combi oven, so confirming available floor space and the correct stand specification in advance is important. If you are replacing an existing combi, it is worth verifying that your current drainage, electrical infrastructure, and ventilation arrangements meet this model's requirements before ordering.

The iCombi Pro 6-2/1 is well suited to high-volume operations — hotel kitchens, large contract catering facilities, central production units, and busy restaurant kitchens where throughput across a full shift justifies the investment. If your service volumes are more modest, a smaller-capacity unit within the iCombi Pro range is likely to serve you better both operationally and economically. For very large-scale production sites, higher-capacity configurations are available in the range.

A unit at this level rewards a proper conversation before purchase — about your kitchen layout, infrastructure, service volumes, and what you are actually cooking day to day. The team is glad to work through all of that with you.

The Rational iCombi Pro 10-2/1 is a full-size electric combination oven built for high-volume commercial kitchen production. It accommodates ten 2/1 GN trays — or up to twenty 1/1 GN positions when loaded in landscape orientation — and operates across steam, convection, and combination modes. The defining characteristic of this model is Rational's iCooking Suite, which manages the cooking process intelligently rather than relying on fixed manual programmes, adjusting conditions in real time according to food type and cabinet load.

In a busy service environment, that level of automation has genuine operational value. The iDensity Control system — combining additional fan wheels, a redesigned cooking cabinet, and active dehumidification — works to maintain consistent climate conditions throughout the cabinet, even under uneven loading or back-to-back cycles. The unit recovers automatically between loads and handles mixed loads without requiring manual reprogramming between items, which reduces both the pressure on kitchen staff and the risk of inconsistent output during long services.

From a practical standpoint, the key operational advantages include:

• Consistent results across mixed loads without manual intervention between items
• iProduction Manager sequences tasks to minimise idle time and reduce energy waste
• Automated cleaning cycle reduces downtime and keeps the cabinet in working condition
• Integrated WiFi supports remote monitoring and recipe management via ConnectedCooking
• Proven improvements in energy and water consumption compared to earlier Rational models

Installation at this scale requires careful advance planning. The 10-2/1 is a large, heavy unit that demands adequate floor space, sound structural support, and proper ventilation — either direct extraction or a suitable canopy hood, depending on your layout. As an electric model it removes the need for a gas supply, but the electrical requirements are substantial and should be confirmed with a qualified electrician well before delivery. If you intend to mount the unit on a base stand, this should be specified at the point of order. Water quality is worth addressing early: a softener or inline filtration unit is generally advisable to protect the steam generator and maintain cleaning performance over time.

This model is best suited to hotel kitchens, large contract catering operations, central production units, and high-volume restaurant kitchens where throughput, consistency, and reliable automated cooking are priorities. It represents a significant capital investment, and for smaller or lower-volume operations a more compact model within the iCombi Pro range is likely to be a more proportionate choice. For sites with very high or continuous production demands, it is worth exploring whether a different configuration would better suit the operation.

Given the scale of investment and the planning involved in installation, it is worth talking through the details with our team before committing — we are happy to work through the practical requirements with you.

The Rational iCombi Pro 20-1/1 is a full-size, twenty-grid electric combination oven designed for high-volume professional kitchens. It operates across steam, convection, and combination cooking modes, with intelligence built directly into the unit — automatically adjusting humidity, temperature, and airflow in response to the load it detects. This is not a passive oven that simply holds a set point; it monitors and responds throughout the cooking process.

In sustained service environments, the iCombi Pro is well suited to high-throughput production. Its load recognition allows it to manage mixed loads — different foods cooking simultaneously — while maintaining appropriate conditions for each. For kitchens running breakfast service, carvery, banqueting, or multi-course production, consistency across twenty grids is operationally significant. The system manages recovery between loads efficiently, which helps reduce batch downtime during peak service.

From a practical standpoint, the iCombi Pro addresses several common operational pressure points:

• Programmable cooking processes reduce reliance on individual chef knowledge and support consistency across shifts
• The iProduction Manager function assists with sequencing multiple dishes and planning output across a service period
• Automated cleaning cycles reduce cleaning time and chemical usage compared with manual processes
• Wi-Fi connectivity enables access to Rational's ConnectedCooking platform for recipe management, remote monitoring, and diagnostics
• The cooking cabinet design supports efficient energy transfer during extended service periods

As a twenty-grid unit, this oven requires careful pre-installation planning. A Type 2 canopy ventilation system will be required in almost all UK installations. Three-phase electrical supply is standard for a unit of this capacity and must be confirmed before ordering. Water inlet and drain connections are also required, and water treatment is strongly recommended to protect the steam generation system and maintain warranty conditions. Footprint, access routes, and floor loading should all be assessed at the planning stage — this is not a unit that can be placed without prior preparation.

The iCombi Pro 20-1/1 is best suited to large-scale catering operations: contract caterers, hotels, hospitals, stadium and event catering, and high-volume restaurant kitchens where consistent output across a large number of covers is a daily requirement. Kitchens with lower throughput or more limited infrastructure may find a smaller-capacity model a more practical fit. For sites where production demands are greater still, rack oven configurations are worth considering.

This is a substantial capital investment with a technically involved installation behind it. If you'd like to work through whether the twenty-grid specification suits your operation, or get a clearer picture of what the installation realistically involves, we're happy to talk it through before you commit.

The Rational iCombi Pro 20-2/1 is a large-format electric combination oven designed for the highest-volume professional kitchen environments. It operates across steam, convection, and combination modes, with the control system automatically managing the balance of heat and humidity according to the programme in use. At this capacity, it sits at the top of the iCombi Pro range and is built to handle large, simultaneous, mixed loads as a matter of routine.

In sustained service, the iDensity Control system — combining multiple fan wheels, an optimised cabinet geometry, and active dehumidification — works to maintain consistent cooking conditions across every shelf position even when the oven is running at full capacity. Maintaining that uniformity across a full load during a busy service is considerably harder than it appears on a specification sheet, and it is where the iCombi Pro genuinely earns its place in demanding kitchens.

From a day-to-day operational standpoint, the features that tend to deliver the most practical value include:

• The iCooking Suite, which manages cooking parameters automatically and adjusts in real time, reducing dependence on individual operator judgement
• The iProduction Manager, which sequences mixed loads to reduce idle time and unnecessary energy consumption
• An automatic cleaning cycle that completes quickly on the standard programme, keeping downtime between services to a minimum
• Integrated WiFi connectivity and access to the ConnectedCooking platform for remote monitoring and programme management
• A visual cooking programme library that helps less experienced staff work accurately without close supervision

Installation at this scale requires careful advance planning. As an electric model, it draws substantial power and will need a dedicated supply — your electrical contractor should assess available capacity before the order is placed. The physical size and weight mean that floor loading, access routes during delivery, and clearance beneath your ventilation canopy all need confirming ahead of time. This is not a unit that can be repositioned easily once in place, so placement decisions should be made at the outset rather than revisited later.

The iCombi Pro 20-2/1 is well suited to large-scale operations: central production kitchens, contract catering facilities, large hotel and banqueting kitchens, and high-volume restaurant environments where cooking substantial quantities across multiple food types simultaneously is a daily requirement. Operations with more moderate throughput would likely be better served by a lower-capacity model from the same range — both operationally and from a running-cost perspective. Sites with specialist demands or unusual configuration constraints are worth discussing in more detail before a commitment is made.

If you are working through whether this unit is the right size for your operation, or need to think through the installation requirements for your site, the team is glad to work through that detail with you before you proceed.

This is a genuine Rational accessory designed to protect the left-hand side panel of the iCombi XS 6-2/3 combi oven from radiant heat generated by an adjacent appliance. It fits directly to the oven's outer casing and acts as a thermal barrier between the unit and any neighbouring heat source — typically a grill, salamander, or solid top range positioned in close proximity.

Without adequate protection, sustained radiant heat from an adjoining appliance can cause gradual damage to the oven's external panels and, over time, the components beneath them. In tightly configured kitchens — compact back-of-house lines, island runs, or sites where equipment has been consolidated to save space — this kind of heat transfer is a genuine operational risk. The shield addresses that directly, allowing the iCombi XS to continue working normally regardless of what is running alongside it.

Being retrofittable, it can be added without repositioning the oven or undertaking significant installation works. This makes it a practical solution during kitchen refits, equipment additions, or line reconfigurations where the relationship between appliances has changed.

• Thermal barrier between the iCombi XS and an adjacent radiant appliance
• Protects left-hand casing in island or close-quarter configurations
• Retrofittable without moving or reconfiguring the oven
• Genuine Rational part, ensuring correct fit and compatibility with the XS 6-2/3
• Straightforward to specify during refits or equipment additions

It is worth confirming your specific iCombi XS configuration and the exact layout of your installation before ordering, particularly if you are working around an existing equipment line. If you are mid-refit and want to talk through whether this shield is the right solution for your setup, we are happy to help.

These are the genuine Rational-formulated cleaning tablets designed specifically for use with the SelfCookingCenter and CombiMaster Plus ranges. They are the red tabs used in Rational's automated cleaning programmes and are sold in a tub of 100.

Rational engineers the chemistry of these tabs alongside the oven's cleaning cycles, which means the concentration and release profile of the active ingredients is calibrated to work with the built-in programme rather than against it. Using third-party alternatives can affect cleaning results and, in some cases, may affect warranty compliance — so operators running Rational equipment are generally better served staying with the manufacturer's own chemistry.

In a busy kitchen, reliable oven hygiene is not just about compliance — it directly affects food quality and oven longevity. Grease and residue left in a combi oven accelerates wear on seals and internal components. Consistent use of the correct cleaning tabs as part of each cleaning cycle helps maintain the oven in the condition it was designed to operate in.

These tabs suit any kitchen running Rational SelfCookingCenter or CombiMaster Plus equipment, from single-unit hotel kitchens through to multi-oven production sites. If you are unsure which cleaning programme or tab type applies to your specific oven model or generation, the team is happy to advise before you order.

Rational Care Tabs are the manufacturer's own maintenance consumable for iCombi Pro, iCombi Classic, and SelfCookingCenter units fitted with CareControl. They are used as part of the oven's automated care cycle, working to protect the internal water circuit and steam-generating components from the gradual accumulation of limescale and mineral deposits.

Water quality has a direct bearing on how consistently a combi oven performs and how long it remains in reliable service. Limescale build-up in the steam system is one of the more common causes of performance drift and unplanned downtime in high-use units. These tabs address that progressively rather than reactively — the formulation is intended to prevent scale taking hold in the first place, which reduces the need for more disruptive descaling procedures that take the oven offline during service.

• Prevents limescale accumulation in the steam circuit during normal operation
• Reduces component wear associated with prolonged mineral deposit build-up
• Supports consistent steam output and cooking performance throughout service
• Integrates directly with the oven's CareControl automated dosing system
• Supplied in a tub suited to regular, ongoing use in a working kitchen

Being a Rational-specified product matters here. The tabs are formulated to work within CareControl as the system was designed to operate. Substituting non-approved alternatives can affect how the care cycle functions and may carry implications for warranty coverage — something worth weighing carefully when comparing against lower-cost options.

Water hardness varies considerably across different parts of the UK, and the appropriate care schedule for a site can differ from one operation to the next. If you'd like to talk through care intervals or water quality considerations for your kitchen, the team is happy to help you work it out.

The Rational iCombi Classic is an electric combination oven that operates across three cooking modes — steam, convection, and a combination of both. The six-grid, full-size GN 1/1 configuration runs one tray per level, making it a practical mid-capacity unit for kitchens that need consistent, repeatable results across a broad range of cooking tasks. The dial-and-push interface with colour display keeps day-to-day operation straightforward without the added complexity of a fully automated platform.

In a working kitchen, the iCombi Classic earns its place through reliability and consistency. The ClimaPlus humidity management system allows operators to set cabinet climate with precision, which matters when producing volume across a structured menu. Multiple fan wheels distribute heat evenly across all six levels, reducing the risk of uneven results during busy service. The ability to store up to 100 multi-step programmes means trained results can be reproduced by any member of the team — a meaningful advantage in kitchens with variable staffing or high turnover.

The day-to-day operational advantages are worth setting out clearly:

• Dial-and-push interface with colour display reduces training time and simplifies operation
• Up to 100 stored multi-step programmes support consistency across shifts and staff changes
• Automatic cleaning system using phosphate-free tablets simplifies end-of-service routines
• Integrated scale prevention within the care programme helps reduce long-term maintenance demands
• High-intensity LED chamber lighting allows quick visual checks without opening the door

As an electric unit, the iCombi Classic requires a suitable three-phase power supply — this should be confirmed with a qualified electrician before installation. Ventilation is a firm requirement; connection to an extraction canopy is standard, though a Rational-compatible ventless hood is an option where canopy installation is not feasible. Water supply and drainage connections are needed for both the steam function and the automatic cleaning system. The unit is a countertop model and requires a properly rated stand or base. Rear access for servicing should be factored into the kitchen layout from the outset.

The six-grid format is well suited to operations producing up to around 60 to 80 covers per service, depending on menu complexity and cooking times. It works reliably in restaurants, boutique hotels, care facilities, and school kitchens where consistent quality at moderate volume is the priority. For higher-volume sites running multiple sittings or large banqueting output, a larger-capacity model within the iCombi range would be worth considering. At the other end, a four-grid unit may be a better fit for very small operations where space and throughput are more modest.

If you are weighing the six-grid Classic against a larger configuration, or considering whether the iCombi Pro platform better suits your service, we are happy to talk through the practical differences before you commit.

The Rational iCombi Classic 10-1/1 is a full-size, ten-grid electric combination oven designed for professional kitchens where consistent, repeatable output across a full service period is a practical necessity. It operates across convection, steam, and combined cooking modes, giving kitchen teams precise control over temperature, humidity, and airflow from a single unit. Up to 100 programmes can be stored, each supporting multi-step cooking sequences — useful where complex menus are in play or where different operators need to reproduce the same results without variation between services.

Under sustained demand the iCombi Classic performs reliably. The fan system distributes heat evenly across all ten levels, which matters when the oven is loaded fully at the height of service and consistent results are needed across every tray simultaneously. The ClimaPlus humidity management system allows the cooking cabinet climate to be adjusted in measured increments, which is particularly relevant for moisture-sensitive products — delicate pastry, proteins where surface finish is critical, or mixed loads where conditions need careful control.

From an operational standpoint, the unit is designed to reduce the margin for error during service:

• Programmable multi-step cooking processes reduce reliance on individual judgement at peak times
• Dial-and-display interface with clear symbols lowers the training burden for new or agency staff
• Automatic cleaning cycles, including an overnight option, reduce manual labour at the end of service
• Phosphate-free cleaning tablets and a built-in descaling function help keep maintenance costs manageable
• High-intensity LED chamber lighting allows quick visual checks without opening the door

Installation requires a suitable three-phase electrical supply and a planned ventilation arrangement — this is not a unit that can be positioned without preparation. It will need to be mounted on a compatible stand or base, and your extraction system must handle the output comfortably. Rational equipment is typically commissioned by a qualified engineer, and it is worth factoring an ongoing maintenance agreement into the total cost of ownership from the outset. Access for servicing should be considered when deciding on placement.

The iCombi Classic 10-1/1 is well suited to mid-to-high-volume operations — hotel kitchens, large restaurant groups, contract catering sites, and institutional catering where a full brigade needs to produce consistent results across multiple services. If your volume is more modest, a smaller grid configuration is likely to represent better value and lower running costs. For very high-throughput sites running back-to-back services at full capacity, a higher-specification model from the Rational range may be worth considering.

If you're working through whether this specification is the right fit for your kitchen and workflow, we're happy to talk it through before you commit.

The Rational iCombi Classic 6-2/1 is a full-size electric combination oven built for commercial kitchens that need to produce large volumes of food consistently across a varied menu. It operates across steam, convection and combination modes, with humidity adjustable in 10% increments, giving kitchen teams precise control over the cooking environment. Up to 100 programmes can be stored, each supporting multi-step cooking sequences of up to 12 stages, which makes repeatable results achievable without depending on individual chef judgement at every point during service.

In a busy kitchen, the 6-2/1 is well suited to mid-to-high volume service. The combination of multiple fan wheels and the cabinet geometry distributes heat evenly across all shelf levels — particularly important when the oven is running at full load through a long service period. The ClimaPlus humidity management system maintains a stable cooking climate, reducing the variability that can creep in when the same dishes are produced repeatedly over several hours.

From an operational standpoint, the iCombi Classic offers several practical advantages for kitchen teams:

• Dial-and-push interface with colour display reduces training time and day-to-day operator error
• Programmable multi-step cooking supports consistent results without constant chef oversight
• Automatic cleaning cycles, including overnight programmes, keep the oven ready for the next service
• Phosphate-free cleaner tabs and built-in scale prevention reduce routine maintenance demands
• High-intensity LED chamber lighting allows cooking progress to be checked without opening the door

Installation requires a three-phase electrical supply and adequate ventilation — either a traditional canopy extraction system or a condensation hood where ducted extraction is not available. The 6-2/1 is a substantial unit and will need significant floor or stand space. It is typically mounted on a purpose-built Rational stand or stacked with a compatible unit where the layout allows. Door swing clearance and access for servicing should both be factored into any kitchen planning before ordering. This is not a unit that can be placed into a poorly ventilated or undersized space without proper preparation.

The iCombi Classic 6-2/1 is a practical choice for hotel kitchens, contract catering operations, staff restaurants and larger restaurant kitchens where throughput and consistency across a broad menu are the priority. It sits within Rational's Classic range, designed for operations that need reliable combination cooking without the additional automated intelligence of the higher-specification iCombi Pro. For operations with lower volumes or tighter budgets, smaller formats within the Classic range are worth considering. For very high-volume central production or cook-chill environments, a larger-capacity configuration may serve better.

If you are working through whether the 6-2/1 is the right size and specification for your site, we are happy to talk it through before you commit to anything.

The Rational iCombi Classic 10-2/1 is a full-size electric combination oven designed for high-volume professional kitchen operations. It operates across three cooking modes — steam, convection, and a combination of both — allowing kitchen teams to roast, bake, steam, braise, and regenerate food within a single unit. The 2/1 GN chamber format accommodates two full-size GN trays side by side across ten levels, making it particularly well suited to large-batch production, banqueting, and multi-course service environments where consistent throughput is essential.

Consistency under pressure is where this oven justifies its place in a demanding kitchen. The ClimaPlus humidity management system monitors and adjusts moisture levels throughout the cook cycle, while multiple fan wheels distribute heat evenly across all ten levels regardless of load. For operations running standardised menus, up to 100 multi-step cooking programmes can be stored, reducing dependence on individual operator knowledge and helping to maintain output quality across different shifts and team compositions.

From a day-to-day operational standpoint, the iCombi Classic offers several practical advantages:

• Dial-and-push interface with colour display reduces training time and handling errors during service
• Automatic cleaning via a phosphate-free tablet system, including an overnight cycle, minimises manual intervention
• Integrated descaling within the care programme helps protect internal components in hard-water areas
• High-intensity LED chamber lighting allows progress to be checked without opening the door
• Humidity adjustable in 10% increments for precise control across a wide range of food types

The 2/1 format carries a significantly larger footprint than a standard 1/1 unit, so adequate space for installation, door swing clearance, and tray handling should be confirmed before ordering. As an electric model, it requires a three-phase power supply — your electrician should verify that the existing supply is suitable ahead of delivery. Extraction above the oven is standard practice in most professional kitchens; if a ventilation hood is not already in place, this is worth addressing as part of the installation plan rather than as an afterthought.

This oven is well suited to hotel kitchens, large contract catering operations, central production units, and high-volume restaurants running multiple cooking processes simultaneously across a full service period. If your kitchen operates at lower or more variable volumes, a 1/1 format or reduced-capacity model is likely to represent better value and a more appropriate footprint. For sites with exceptionally high throughput or back-to-back service periods, it is worth considering whether a larger configuration would better match the operational demand.

If you would like to talk through whether this model is the right match for your kitchen before making a decision, our team is happy to help you work through it.

The Rational iCombi Classic 20-1/1 is a full-size, 20-grid electric combination oven designed for high-volume professional kitchens. It operates across three cooking modes — convection, steam, and a combination of both — enabling kitchen teams to roast, bake, steam, braise, and regenerate within a single unit. Up to 100 multi-step programmes can be stored, supporting consistent, repeatable results across different shifts without depending on individual operator knowledge.

In a demanding service environment, the ClimaPlus humidity management system is one of the more operationally significant features. The ability to set cabinet humidity in defined increments gives kitchen teams precise control over cooking conditions, which supports better product yield, more uniform finishes, and a reduced risk of overcooking during busy service periods. Multiple fan wheels distribute heat evenly across all 20 rack positions, so full-capacity loads perform as reliably as lighter ones — an important consideration when the oven is running at its limits during peak service.

The day-to-day operational advantages worth noting:

• Programmable multi-step cooking reduces reliance on experienced staff for consistent output
• Precise humidity control across cooking modes improves yield on a wide range of menu items
• Even heat distribution supports reliable results at full 20-grid capacity
• Automatic cleaning with phosphate-free tabs and integrated scale prevention
• High-intensity LED chamber lighting allows quick visual checks without opening the door

A unit of this size requires a three-phase electrical supply, adequate ventilation, and careful space planning — particularly around door swing clearance and tray extraction depth. A suitable stand or base unit will be needed unless the oven is being installed into an existing rack arrangement. Given the size, weight, and electrical requirements, a site survey before ordering is strongly advisable.

The iCombi Classic 20-1/1 is well suited to hotel kitchens, contract catering operations, central production units, hospital catering, and large restaurant kitchens where consistent high-volume output is a daily requirement. For operations where a 20-grid unit would rarely run at meaningful capacity, a smaller model within the iCombi Classic range is likely a more proportionate investment. For very large central production facilities with greater throughput demands, higher-capacity options exist within the Rational range.

If you'd like to discuss whether this unit is the right fit for your service volume, kitchen layout, or available power supply, the team is happy to work through the detail with you.

The Rational iCombi Classic 20-2/1 is a large-format electric combination oven designed for high-volume commercial kitchen environments. It operates across three cooking modes — steam, convection, and a combination of both — giving kitchen teams precise, independent control over temperature, humidity, and airflow within a single unit. The 20-2/1 configuration is one of the largest in the iCombi Classic range, and represents a serious capital commitment that warrants careful specification before purchase.

In a demanding service environment, consistency across a fully loaded cabinet is what separates a well-specified combi oven from one that struggles under pressure. The iCombi Classic uses multiple fan wheels working in conjunction with the cooking chamber geometry to circulate heat evenly across all levels simultaneously. The ClimaPlus humidity control system allows fine adjustment of the cooking climate, which in practice means kitchen teams can move between roasting, steaming, and regeneration without significant recovery time between loads. Door-opening recovery is reliable — an important consideration when multiple chefs are loading and unloading continuously during a busy service.

From an operational standpoint, the iCombi Classic is built to reduce the margin for error across shifts and skill levels:

• Up to 100 programmable cooking sequences, each with up to 12 steps, support consistency across the team
• Rotary dial with push function and colour display keeps the interface accessible under service pressure
• Automatic overnight cleaning cycle with phosphate-free tablets reduces morning preparation time
• Integrated descaling within the care programme helps protect internal components over time
• High-intensity LED chamber lighting allows visual monitoring without opening the door

At this scale, installation planning is essential before ordering. The unit is large and heavy, requiring a clear delivery route and adequate floor space. As an electric model, a suitable three-phase power supply is required — your electrician and Rational's installation guidelines should both be consulted early in the process. Ventilation requirements are considerable, and a correctly specified extraction canopy should be confirmed with your kitchen installer. Water connection and drainage are also required for steam generation and the integrated cleaning functions.

The 20-2/1 iCombi Classic is well suited to large-scale operations where throughput justifies the footprint and capital investment — central production kitchens, large contract catering sites, stadium and event catering, and high-volume institutional or hotel operations. For kitchens with more moderate output or tighter space constraints, smaller configurations within the iCombi Classic range are worth considering. For operations that need greater automation or connected kitchen functionality, Rational's iCombi Pro series is worth exploring as part of any specification conversation.

If you're working through the right size for your operation, confirming power and ventilation requirements, or comparing configurations, the team is happy to work through the detail with you before anything is decided.

This is Rational's own liquid detergent, developed specifically for use with CombiMaster and ClimaPlus combi ovens. It is supplied in a 10-litre container and is designed to be used as part of the oven's built-in automatic cleaning programme rather than as a general-purpose cleaner.

Rational combi ovens are built with an integrated cleaning system that meters detergent and rinse aid automatically through each cleaning cycle. Using the correct detergent matters here — the dosing system is calibrated for Rational's own chemistry, and using an incompatible product can affect cleaning performance, leave residues, or in some cases cause issues that may affect warranty coverage. This detergent is formulated to work within that system without modification.

In practical terms, the auto-clean function on these ovens is designed to run at the end of service with minimal operator involvement. The detergent does the heavy work on baked-on grease and food residues inside the cavity, so that the oven is ready for the next service without requiring manual scrubbing. For a busy kitchen running multiple services a day, this makes a meaningful difference to kitchen workflow and hygiene consistency.

This product is straightforwardly suited to any site already running a Rational CombiMaster or ClimaPlus oven that uses the automatic cleaning cycle. It is a consumable that needs regular replenishment — the 10-litre volume is a practical supply for most kitchens over several weeks, depending on cleaning frequency and programme intensity selected.

If you are unsure which cleaning products are correct for your specific Rational model, or how to set up cleaning programmes for your kitchen's usage pattern, the team is happy to help clarify before you order.

This is Rational's own-brand liquid descaler, developed specifically for use with CombiMaster and ClimaPlus Combi ovens. It is designed to remove limescale build-up from the oven's water system and steam generation components — the kind of build-up that, if left unchecked, gradually undermines cooking performance and shortens equipment lifespan.

In hard and medium-hard water areas, scale accumulation is one of the most common causes of reduced steam output and inconsistent cooking results in combi ovens. Regular descaling with the correct product helps keep the steam generator and internal water pathways clear, maintaining the cooking conditions the oven was calibrated to deliver.

Using Rational's own descaler rather than a generic alternative is worth considering. Rational's combi ovens are precision pieces of equipment with specific material tolerances, and the manufacturer's own chemistry is formulated to be compatible with those components. Using non-approved products can, in some cases, affect internal parts or void servicing arrangements.

• Formulated specifically for Rational combi oven water systems
• Helps maintain steam output and cooking consistency
• Supports compliance with Rational's recommended maintenance programme
• Suitable for use in hard and medium-hard water areas
• Part of a complete Rational chemical care range

How frequently you descale will depend on your local water hardness and how heavily the oven is used. Kitchens in hard water regions running the oven through multiple service periods daily will typically need to descale more often than lighter-use sites.

If you're unsure about the correct descaling frequency for your site, or whether your water hardness warrants additional water treatment measures, the team is happy to advise.

The Rational iCombi UltraVent is a condensate canopy designed to sit directly on top of compatible Rational iCombi ovens in the 61 and 101 configurations. Rather than allowing steam and cooking vapour to disperse into the kitchen when the oven door opens or through the top exhaust vent, the UltraVent captures and condenses that moisture internally. It connects to the oven's own sensor system, so extraction operates automatically in coordination with the cooking cycle — including the critical moment the door is opened mid-cook or at the end of a programme.

In kitchens where running conventional ductwork to an external exhaust point is impractical, costly, or not permitted, the UltraVent offers a workable alternative. It requires no connection to the outside of the building and no mechanical extract infrastructure, which makes it particularly relevant for operators in listed buildings, basement kitchens, temporary or pop-up sites, or anywhere that landlord restrictions or planning constraints make a ducted system difficult to approve. It is also retro-fit compatible, so existing iCombi 61 and 101 installations can be upgraded without significant disruption.

Practical advantages for kitchen operators include:

• No external ducting required — simpler, less disruptive installation
• Sensor-linked operation responds automatically to the oven's cooking cycle
• Captures vapour from both the door opening and the top exhaust vent
• Reduces steam build-up in the kitchen during busy service periods
• Retro-fit compatible with existing iCombi 61 and 101 installations

It is important to be clear about where the UltraVent is and is not appropriate. It performs well where steaming and combination cooking account for the majority of oven use. If the oven is regularly used for high-temperature roasting, heavy browning, or grilling — processes that generate smoke and grease-laden air rather than primarily steam — the UltraVent alone is unlikely to be sufficient, and a conventional ducted canopy should be considered instead. It is also worth confirming with your local building control or environmental health officer whether a condensate canopy satisfies ventilation compliance requirements for your specific premises and menu type before committing to installation.

The UltraVent is well suited to independent restaurants, hotels, and contract caterers running iCombi 61 or 101 ovens where a full canopy installation is not feasible and the majority of cooking involves steam or combination steam functions. It is less appropriate for operations centred on dry roasting or heavy grilling, where a ducted extraction solution remains the more reliable choice.

If you are weighing up whether the UltraVent is the right ventilation solution for your kitchen, a conversation about your oven use, menu, and premises will help clarify the decision before any installation work is committed to — the team is happy to talk it through.

The Rational iCombi UltraVent Plus is a condensate canopy designed to sit directly on top of a Rational iCombi oven — specifically the 6-2 and 10-2 models. Its purpose is straightforward: to capture steam and cooking odours at source, both from the oven's exhaust vent and from door openings during service. Rather than operating as a standalone extraction unit, it connects directly to the oven's own sensors and responds automatically to what the oven is doing in real time.

In a busy kitchen, unmanaged steam from a combi oven creates practical problems — condensation on ceilings and walls, discomfort for staff, and potential compliance concerns in open or customer-facing environments. The UltraVent Plus addresses this by managing condensate internally, which means no ducting to an external wall is required. That distinction matters considerably in locations where running conventional extraction infrastructure would be structurally difficult, expensive, or simply not possible.

The main operational advantages are worth setting out clearly:

• No external ducting required — condensate is managed entirely within the unit
• Sensor-linked operation responds automatically to cooking cycles and door openings
• Retro-fit compatible with existing iCombi 6-2 and 10-2 installations
• Reduces steam and odour impact in open-kitchen and customer-facing spaces
• Typically simpler and lower-cost to install than a conventional extraction canopy

The UltraVent Plus is well suited to hotel dining rooms, retail food operations, front-of-house kitchen settings, and older or listed buildings where conventional extraction cannot easily be installed. It performs reliably where the iCombi is used across a range of cooking modes with frequent door openings. That said, for very high-throughput operations running continuous combi cycles over extended service periods, it is worth considering whether a full extraction canopy system would serve the kitchen better — a condensate canopy and a conventional extraction solution are not always interchangeable, and the right choice depends on the specific ventilation demands of the site.

If you are working through ventilation options for a new or existing installation, the team is happy to talk it through before you make a decision.

The Rational iCombi UltraVent Plus is a recirculation canopy designed to sit directly on top of the iCombi combi oven in its 6-1 and 10-1 configurations. It integrates with the oven's internal sensors to operate automatically — activating when the oven is in use and capturing steam, vapour, and cooking odours at source each time the door opens, before they have a chance to spread into the surrounding kitchen.

Where the UltraVent Plus differs from the standard UltraVent is in its additional filtration capacity. The standard model handles steam and condensation reliably in most situations, but the Plus incorporates specialist filter layers designed to deal with smoke and grease-laden vapour produced during high-temperature grilling and roasting programmes. For kitchens using the iCombi across its full range — baking, steaming, and intensive roasting — the Plus is generally the more appropriate choice.

The practical value of a recirculation canopy is that it removes the need for external ductwork entirely. This has real consequences for installation and operational flexibility:

• The oven can be positioned to suit the workflow, not constrained by where ducting can be run
• Retrofitting to an existing iCombi installation is straightforward
• Well suited to front-of-house and theatre kitchen settings, and to leased premises where structural modifications are not practical
• Ongoing maintenance costs are limited to periodic carbon filter replacement
• Direct oven integration means no separate electrical wiring is required

It is worth being clear about what recirculation technology does not address. It will not remove heat from the room in the way that ducted extraction does. In enclosed or poorly ventilated spaces, ambient temperature will still rise during sustained service, and room ventilation should be considered as a separate matter alongside the canopy.

The UltraVent Plus is well suited to operators running the iCombi across its full range of cooking modes who need a clean, practical extraction solution without building works. For larger 20-1 configurations or high-volume sites where heat output is a significant concern, a ducted extraction solution is likely the better approach.

If you are working out whether a recirculation canopy is the right fit for your kitchen setup, we are happy to talk through the specifics before you commit to anything.

The Rational iCombi UltraVent is a recirculation canopy designed to sit directly on top of compatible Rational iCombi ovens in the 62 and 102 size configurations. Rather than routing steam and cooking vapours out through the building fabric via a duct run, the UltraVent captures exhaust from the oven's top vent and from the door opening, filters and condenses it internally, and returns the cleaned air to the kitchen. It connects directly into the oven's sensor system, so the canopy responds automatically during normal operation and whenever the door is opened mid-service.

For kitchens running combi ovens heavily on steam functions — poaching, steaming, sous vide finishing, or regeneration cycles — this means vapour is managed at source rather than dispersing across the kitchen. The canopy handles both the steady exhaust from the oven's top vent and the burst of steam released each time the door is opened during a busy service. Operators commonly find this makes a noticeable difference to kitchen comfort and reduces condensation on nearby surfaces and equipment.

The main practical advantages are straightforward:

• No duct run required — removes a significant installation barrier on many sites
• Integrates directly with the oven's controls via internal sensors for automatic response
• Carbon and multi-layer filtration captures cooking odours as well as moisture
• Can be retro-fitted to an existing installation without structural work
• Ongoing maintenance is limited to periodic filter changes — no external connections to service

It is worth being clear about the limits of this version. The standard UltraVent is optimised for steam-led cooking profiles. Kitchens with a significant proportion of grilling, high-temperature roasting, or fat-heavy cooking cycles may find the UltraVent Plus variant — which carries additional filtration for smoke and heavier vapour — better matched to their workload. If your operation involves a mix of both, it is worth discussing your cooking profile before deciding which version is appropriate.

This canopy is well suited to sites where installing a traditional extraction duct is impractical — listed buildings, rented premises, temporary or modular kitchens, and dark kitchens where structural work is not feasible. It is also commonly used where a combi oven has been added to an existing kitchen without the ventilation infrastructure to support ducted extraction.

If you are unsure which UltraVent variant suits your kitchen's cooking profile, or whether your current installation would support a retro-fit, we are happy to talk it through before you commit to an order.

The Rational iCombi Classic 10-2/1 is a full-size gas combination oven built for sustained, high-volume production. It operates across three cooking modes — steam, convection, and combination — and is available in both natural gas and LPG configurations, which makes it a practical option for sites where mains gas is unavailable or where LPG is the established fuel source.

In a demanding kitchen environment, the iCombi Classic performs consistently under the kind of load that exposes weaker equipment. The combination mode manages heat and moisture simultaneously, shortening cooking times and supporting uniformity across a full rack of product. Rational's ClimaPlus humidity system allows cabinet moisture to be adjusted in fine increments, which gives chefs meaningful control when different dishes are running concurrently. Multiple fan wheels distribute heat evenly throughout the cavity — a detail that matters most when running at full capacity during a heavy service.

From a practical standpoint, the iCombi Classic addresses several day-to-day operational concerns:

• Up to 100 saved multi-step programmes support consistency across different staff and shifts
• Precise humidity control reduces guesswork and helps maintain output quality at volume
• LED chamber lighting allows visual checks without opening the door and losing cabinet conditions
• Automatic cleaning cycles, including an overnight option, reduce manual workload between services
• An integrated care system manages scale build-up — particularly relevant in hard-water areas

Installation requires careful planning. The unit needs a gas supply matched to the configured fuel type, a dedicated water supply and drain for steam generation and automatic cleaning, and adequate ventilation via a suitable extraction canopy or compatible ventilation hood. The oven is large and heavy, so access routes, floor loading, and service clearances should all be assessed before delivery is arranged. Installation must be carried out by a qualified gas engineer, and commissioning by a Rational-approved engineer is strongly advisable to ensure the unit is correctly configured from the outset.

The 10-2/1 configuration is best suited to high-volume operations: large restaurant kitchens, hotel banqueting, contract catering, staff dining facilities, and central production units where throughput demands are consistent and significant. Smaller kitchens, or operations with lighter and more variable output, are likely to be better served by a smaller rack configuration that is more economical to run day-to-day. Conversely, sites with very high or growing production demands should consider whether a single unit is sufficient or whether a two-unit installation would better match peak capacity requirements.

A combi oven at this level is a long-term capital commitment, and getting the specification right from the start matters. If you would like to talk through whether the 10-2/1 suits your kitchen's output, infrastructure, and service pattern, the team is happy to work through it with you before you commit.

The Rational iCombi Pro in its six-grid, full-size GN gas configuration is an intelligent combination oven built for professional kitchens that need reliable, repeatable results across a varied menu. It is available in both natural gas and LPG variants, which is worth confirming before ordering — the two have different injector and pressure requirements and cannot be converted on site after delivery.

What separates the iCombi Pro from a conventional combination oven is its iCooking Suite, a control system that monitors and adjusts the cooking process in real time in response to what is actually loaded. Rather than running a fixed programme and expecting a consistent outcome regardless of load, the oven senses quantity, moisture content, and browning level and compensates accordingly. The iProduction Manager extends this further, allowing multiple items to be sequenced and cooked simultaneously — a genuine operational advantage during complex service periods or where staffing levels vary between shifts.

In practical terms, this translates to a number of day-to-day operational benefits:

• Automatic load sensing delivers consistent results across mixed loads without manual intervention
• Integrated Wi-Fi connects to Rational's ConnectedCooking platform for recipe management and HACCP data logging
• Guided touchscreen interface reduces dependency on individual operator skill and shortens training time
• Automated cleaning cycles help keep downtime between services to a minimum
• Enhanced de-humidification maintains food quality across a broad range of cooking styles

Installation requires a certified gas engineer. The unit needs a mains water supply, a drain connection, and adequate extraction via a commercial canopy. A water softener is strongly recommended to protect the steam system and maintain cleaning performance over time. The six-grid format is suited to countertop or stand-mounting, and the base or stand arrangement should be confirmed as part of your kitchen planning before delivery.

This configuration is well suited to restaurants, hotel kitchens, contract caterers, and smaller institutional operations running one or two services daily. It handles the kind of service volume that would consistently overload a conventional oven while fitting realistically into kitchens where space is a consideration. For multi-service restaurants, production kitchens, or banqueting operations with higher throughput demands, a larger-capacity model from the same range is likely to be a better fit.

If you are working out whether this configuration suits your service volumes, kitchen layout, or gas supply, our team is well placed to work through the detail with you before you commit.

The Rational iCombi Pro 10-1/1 is a full-size gas combination oven built for professional kitchens that need to produce consistently across every service. It accepts ten 1/1 GN trays across ten shelf positions and runs on either natural gas or LPG, making it a practical option for sites where electrical infrastructure is limited or where gas is the preferred energy source. This is a production-grade unit engineered to handle continuous, heavy use across multiple services.

What sets the iCombi Pro apart in day-to-day operation is its ability to deliver consistent results without depending on constant operator intervention. The iCooking Suite monitors conditions inside the cabinet throughout each cycle and adjusts automatically to reach the target result, whether the load is full or partial, uniform or mixed. The iDensity Control system manages airflow distribution across all ten positions, which supports even cooking when the oven is pushed hard at peak service — something that matters when you are moving through thirty or forty covers in a single cycle. In kitchens where staffing levels vary, that kind of process reliability has genuine operational value.

Several features translate directly into practical advantages for kitchen teams:

• Automatic cleaning cycles reduce downtime between services
• iProduction Manager sequences multi-item loads, supporting smaller teams handling complex menus
• Integrated Wi-Fi connects to Rational's ConnectedCooking platform for remote monitoring and recipe management
• Touchscreen interface with visual prompts reduces training time for new staff
• Natural gas and LPG compatibility gives flexibility across different site types

Installing a gas combi oven of this class requires careful preparation. The site must have a suitably rated gas supply at the correct working pressure, and commissioning must be carried out by a Gas Safe registered engineer — this is a legal requirement, not a recommendation. Adequate extraction is essential: either a canopy system with sufficient capacity or a Rational-approved ventless hood where traditional extraction is not feasible. The unit is substantial in weight and requires a stable, level base or a compatible stand. It is worth confirming access routes before delivery, particularly in basement kitchens or premises with narrow doorways or restricted goods lifts.

The iCombi Pro 10-1/1 is well suited to hotel kitchens, busy restaurant and brasserie operations, contract catering sites, and central production units where a broad menu needs to move reliably across multiple services. It is also commonly used in education and healthcare catering where batch cooking and meal regeneration are part of the daily routine. For lighter-volume operations or tighter budgets, smaller-capacity models within the Rational range may represent better value. For very high-output sites running multiple shifts, it is worth considering whether an additional unit or a larger cabinet would better meet throughput demands.

If you would like to talk through how this oven fits your service pattern, gas supply, or extraction setup, our team is happy to work through the detail with you before you commit.

The Rational iCombi Pro 6-2/1 is a full-size gas combination oven designed for professional kitchens that need reliable, consistent results across a broad range of cooking methods and food types. It operates across six levels, each accepting two 2/1 GN pans in landscape orientation, and is available in both natural gas and LPG configurations — a practical consideration for sites where mains gas supply is limited or variable.

In service, the iCombi Pro is built to handle continuous and unpredictable demand. Rational's iDensity Control system maintains even heat and humidity distribution throughout the cabinet, which matters most when loading mixed products simultaneously — something that happens routinely in a busy kitchen but rarely under controlled conditions. The oven adjusts its cooking parameters intelligently based on what is loaded, which helps protect consistency even when the pass is under pressure and staff are moving quickly.

From an operational standpoint, several features translate into meaningful day-to-day advantages:

• iCooking Suite guides cooking processes intelligently, reducing reliance on individual operator experience
• iProduction Manager supports mixed-load planning, helping maximise cabinet utilisation during peak service
• Integrated cleaning programme completes quickly, reducing downtime between service periods
• Built-in WiFi enables connection to Rational's ConnectedCooking platform for remote monitoring and recipe management
• Natural gas and LPG options support a wider range of site infrastructure

Installation requires thorough pre-planning. A gas connection at the correct supply pressure is a fundamental prerequisite, and the unit must be installed beneath a suitable ventilation solution — either a canopy extraction system or a Rational-approved ventless filtration hood where canopy extraction is not feasible. The 6-2/1 carries a substantial footprint and considerable weight; access routes, floor loading capacity, and clearances from adjacent equipment should all be confirmed before delivery is booked. Commissioning must be carried out by a Gas Safe registered engineer — this is a regulatory requirement, not an optional step.

This configuration sits in the mid-range of the iCombi Pro family and is well suited to hotel restaurants, contract catering operations, busy pub kitchens, and staff catering facilities running moderate to high service volumes. It offers genuine capacity without demanding the full floor-space commitment of the larger variants in the range. Kitchens with lighter throughput requirements may find a smaller configuration a more proportionate fit, while very high-volume operations — large banqueting facilities, production kitchens, or central kitchens cooking for distribution — should consider whether a higher-capacity model better matches their demand profile.

If you are working through whether the 6-2/1 is the right size for your operation, or have questions around gas supply, ventilation, or how this unit fits into your existing kitchen layout, the team at Advantage Catering Equipment is happy to work through the details with you.

The Rational iCombi Pro 10-2/1 is a ten-level, full-size gas combination oven built for sustained, high-volume production cooking. It runs in landscape orientation, accepting two 2/1 GN pans per level across all ten shelves, and is available in natural gas and LPG configurations — a practical consideration for sites where mains electrical capacity is limited or where gas is the preferred energy source.

In service, the iCombi Pro is engineered to hold consistent output under the kind of continuous pressure that reveals the limitations of lesser equipment. The iCooking Suite monitors and adjusts cooking conditions throughout each cycle, keeping quality stable whether the load is uniform or a mixed batch of proteins, vegetables and bakery items running simultaneously. The iDensity Control system manages airflow and climate distribution across the full height of the cabinet, so results at the top shelf remain as reliable as those at the bottom — even when the oven is running at capacity during a heavy service period.

From a day-to-day operational standpoint, the iCombi Pro offers several practical advantages:

• Intelligent load recognition adjusts cooking conditions automatically, reducing manual intervention during service
• The iProduction Manager sequences mixed loads to optimise timing and energy use across the cabinet
• Automated cleaning cycles are efficient and require minimal operator involvement between services
• Integrated Wi-Fi supports connection to Rational's ConnectedCooking platform for remote monitoring and recipe management
• Programme-driven cooking reduces reliance on individual chef skill for consistent, repeatable production results

Installation requires careful planning. The unit is substantial in both footprint and weight, and will need a dedicated gas supply with pressure and flow rates confirmed by a Gas Safe registered engineer prior to commissioning. Ventilation is a firm requirement — the oven must sit beneath a canopy or connect to a ventilation system appropriately rated for gas equipment at this output level. A floor stand or compatible base unit will be required at most sites. If ConnectedCooking is part of the plan, a stable network connection in the kitchen needs to be in place before installation. These are not complications unique to this model, but they do need working through at the planning stage rather than on the day the unit arrives.

The 10-2/1 is well suited to high-volume operations — hotel kitchens, contract catering facilities, large restaurant groups and central production units where consistent output across extended service periods is a priority. For lower cover counts, a six-level configuration is often a more proportionate fit. Sites running very high throughput across multiple meal periods may find a larger-capacity model better aligned to their production requirements. The gas configuration is particularly relevant where electrical supply is a constraint or where energy cost comparisons favour gas.

Working out which capacity, fuel type or configuration best fits your kitchen is worth doing before you commit. Our team is happy to talk it through with you.

The Rational iCombi Pro 20-1/1 is a full-size, twenty-rack gas combination oven and one of the largest units in the iCombi Pro range. It is built for sites that need to produce serious volumes of food across multiple service periods — not just occasional high-output days. The unit accepts twenty full-size 1/1 GN pans in portrait orientation and can be supplied for either natural gas or LPG, giving operators flexibility depending on their site's fuel infrastructure.

What distinguishes the iCombi Pro in a working kitchen is its iCooking Suite, which monitors conditions inside the cooking cabinet continuously and adjusts heat, humidity, and airflow in response to what is actually happening — rather than running a fixed programme regardless. This matters when loads vary between services or when different food types are cooking simultaneously. The iDensity Control system optimises fan performance and cabinet airflow to support larger and mixed loads without sacrificing cook quality. For high-volume operations where a chef cannot monitor the oven throughout a service, that level of automated adjustment has real operational value.

From a day-to-day standpoint, the practical advantages include:

• The iProduction Manager sequences cooking across multiple food types, reducing idle time between loads
• Automated cleaning can complete a standard cycle quickly, keeping kitchen downtime to a minimum
• The touchscreen interface uses visual prompts, supporting consistent use across teams with varying experience
• Integrated Wi-Fi allows remote monitoring and recipe management via Rational's ConnectedCooking platform
• Natural gas and LPG configurations are both available to suit different site setups

Installation requires a stable gas supply appropriate to the configuration chosen, a plumbed water connection and drain for steam generation and cleaning, and adequate ventilation or an extraction canopy above the unit. This is a substantial piece of equipment — access routes into the kitchen should be checked before ordering. If the site operates at altitude or has non-standard gas supply pressure, this should be confirmed with a qualified installer before commissioning.

This model is best suited to large hotel kitchens, central production units, contract catering operations, stadium and events venues, and restaurant groups running extended service periods at scale. Sites with more moderate throughput may find a smaller configuration within the iCombi Pro range more appropriate. For operations that need to go beyond even this capacity, a multi-unit installation is worth considering as part of the kitchen plan.

If you want to talk through whether this model fits your kitchen — in terms of capacity, gas supply, or how it sits alongside your existing equipment — our team is glad to help you work that out before you make a decision.

The Rational iCombi Classic 20-2/1 is a large-format gas combination oven designed for high-volume professional kitchens. It operates across three modes — steam, convection, and a combination of both — giving kitchen teams precise control over heat and humidity throughout service. The 2/1 GN format accommodates up to 20 full-size pans in landscape orientation, making it one of the highest-capacity configurations in the iCombi Classic range and a practical choice wherever large batch cooking is a daily requirement.

In a demanding service environment, consistency across a full load matters as much as raw capacity. The iCombi Classic uses multiple fan wheels to distribute heat evenly across all rack positions, reducing the risk of uneven results when cooking at full capacity. The ClimaPlus humidity management system allows the cabinet climate to be adjusted in defined stages, which gives cooks reliable control during multi-step processes. Programmes can be saved and recalled with consistency across shifts, reducing dependence on individual operator knowledge during peak periods.

From a day-to-day operational standpoint, the iCombi Classic offers several practical advantages:

• Up to 100 saved programmes with multi-step cooking sequences of up to 12 steps
• Dial-and-push interface with colour display, reducing training time and operator error
• Automatic cleaning with overnight capability using phosphate-free tablets
• Integrated scale prevention within the care system, supporting longer service life
• High-intensity LED chamber lighting for visual checks without opening the door

The 20-2/1 is a substantial unit and warrants careful planning before installation. Gas supply, ventilation, and extraction capacity must all be confirmed as appropriate for a unit of this output before ordering. Professional installation is standard practice. The physical footprint and weight mean that access routes and floor loading should be assessed in advance. The unit can be configured for either natural gas or LPG supply — worth confirming with your gas engineer early, before delivery is scheduled.

This model is best suited to high-volume operations: large contract catering sites, central production kitchens, stadium and events catering, and large hotel or restaurant kitchens where multiple full-size GN loads are prepared simultaneously throughout the day. For kitchens with lower throughput, the iCombi Classic is available in smaller rack configurations that may represent a more proportionate investment. For sites where advanced cooking intelligence or connectivity features are a priority, Rational's broader range includes models worth considering alongside this one.

A combination oven at this scale is a long-term commitment, and getting the specification right from the outset avoids complications further down the line. If you'd like to talk through the capacity requirements, installation considerations, or how this model compares to others in the range, the team is glad to help.

The Rational iCombi Classic 20-1/1 is a full-size, twenty-grid gas combination oven designed for high-volume professional kitchens. It operates across three modes — steam, convection, and combination — giving kitchen teams direct control over temperature, moisture, and airflow throughout service. The unit can be configured for natural gas or LPG, which is worth confirming before order if your site runs on bottled gas.

Built to handle sustained throughput, the iCombi Classic distributes heat evenly across all twenty levels through multiple fan wheels, maintaining consistent results across a full load rather than just the central shelves. The ClimaPlus humidity management system allows operators to adjust moisture levels in defined steps — useful when moving between product types during a single service, whether roasting, baking, or regenerating — without the inconsistency that less controlled systems can produce.

From an operational standpoint, the iCombi Classic offers several practical advantages for busy kitchen teams:

• Up to 100 programmable multi-step cooking profiles, supporting consistent results across shifts and varying skill levels
• Intuitive dial-and-display interface with clear symbols, reducing operator error under pressure
• Automatic cleaning cycles including an overnight option, using phosphate-free cleaner tablets with a built-in descaling function
• High-intensity LED chamber lighting for monitoring cooking progress without opening the door
• Reproducible batch results, reducing reliance on individual chef judgement during high-volume service

A twenty-grid unit is a substantial installation and requires careful planning before delivery. Gas connection, adequate ventilation, and confirmed floor-loading capacity are all prerequisites. Most sites will need a correctly positioned grease extract canopy above the unit. Given the size and weight involved, access routes and kitchen layout should be assessed in advance. Installation requires a qualified gas engineer and, in most cases, a ventilation specialist.

This model is well suited to large hotel kitchens, contract catering facilities, central production units, and high-volume restaurant kitchens producing at scale. Operations with lower throughput or more limited space would be better served by a smaller-capacity model within the iCombi Classic range. For very large production environments with greater demands still, a higher-capacity alternative may be worth considering.

If you are working through whether this capacity is the right fit for your operation, or need to think through the installation requirements before committing, our team is happy to talk it through with you.

The Rational iCombi Classic 6-2/1 is a large-format gas combination oven designed for sustained, high-volume production. It operates across six shelves in a 2/1 GN configuration, accommodating two 1/1 GN pans per level in landscape orientation. Steam, convection and combination modes are all available, with humidity managed through Rational's ClimaPlus system, which allows fine-grained adjustment and actively responds to moisture levels inside the chamber. That combination of capacity and climate control means the unit can handle proteins, baked goods and vegetables across the same service without requiring manual intervention between loads.

Even heat distribution across a full cabinet is handled by up to three fan wheels working with the internal geometry to reduce hot spots during peak demand. The ClimaPlus system takes much of the manual adjustment out of the process, which supports consistency across kitchen teams of varying experience levels — a practical consideration in high-turnover environments.

From a day-to-day operational standpoint, the iCombi Classic offers several advantages worth noting:

• Up to 100 stored programmes with multi-step processes of up to 12 steps, supporting repeatable results across the team
• Dial-and-push interface with colour display, keeping the learning curve manageable for new or temporary staff
• High-intensity LED chamber lighting for visual checks without opening the door mid-cook
• Automatic cleaning system with overnight capability and phosphate-free tablets, reducing manual cleaning time
• Integrated scale prevention within the care cycle, which matters in hard-water areas

Installation requires careful planning. As a gas unit of this size, a commercial extraction canopy rated for gas cooking equipment is a standard requirement. The cabinet's footprint and weight are considerable — floor loading capacity, delivery access and door-swing clearance should all be assessed before the unit arrives on site. Gas connection, whether natural gas or LPG, must be completed by a Gas Safe registered engineer. Adequate clearance for pan loading and door operation without disrupting kitchen workflow should also be factored into the layout.

This model is well suited to hotel kitchens, contract catering operations, central production units, banqueting facilities and larger restaurant groups where multi-mode, high-volume cooking is a daily requirement. For single-site operations with moderate covers, a lower-capacity unit within the iCombi Classic range is likely to be a better operational and financial fit. Sites with exceptionally high throughput or more complex production demands may find it worth exploring whether a larger or more specification-heavy model within the broader Rational range is more appropriate.

If you are working through whether this configuration, fuel type or capacity level is right for your kitchen, our team is happy to talk through the specifics with you before you commit.
