Rational iCombi Pro 20-1/1 Gas Combination Oven

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.
Frequently asked questions
Is the 20-rack model the right capacity for our operation, or should we consider a smaller unit?
The 20-1/1 is designed for genuinely high-volume sites — large hotels, central production kitchens, contract caterers, and events venues running extended services. If your kitchen operates at moderate throughput or has limited floor space, a smaller configuration within the iCombi Pro range is likely a better fit and will run more efficiently for your actual load. It is worth discussing your typical covers and service pattern with us before deciding on capacity.
What are the key installation requirements for this oven?
The unit requires a gas supply matched to the configuration ordered — either natural gas or LPG — along with a plumbed cold water connection and a floor drain for steam generation and the automated cleaning function. Ventilation is essential; in most commercial kitchens this means a suitable extraction canopy directly above the oven. Given its size and weight, access routes into the kitchen should be measured and checked before the unit is ordered, and commissioning must be carried out by a Gas Safe registered engineer.
How does the iCombi Pro handle mixed loads during a busy service?
The iDensity Control system adjusts fan speed and airflow distribution within the cabinet to compensate for varying load sizes and food types cooking simultaneously. Combined with the iCooking Suite's continuous monitoring of humidity and temperature, this means the oven adapts in real time rather than holding fixed parameters — which is particularly useful when output demands shift between service periods or when different menu items are running at the same time.
