Rational iCombi Classic 20-1/1 Gas Combination Oven

Delivery Information
Price Match
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.
Frequently asked questions
Is a twenty-grid combi oven the right capacity for my kitchen?
A twenty-grid unit is designed for operations producing at genuine scale — large hotel kitchens, contract catering facilities, and central production units typically make best use of this capacity. If your service volumes are lower or your kitchen space more constrained, a smaller model within the iCombi Classic range is likely to be a more practical and cost-effective fit. It is worth working through your likely tray throughput per service before committing to this size.
What are the key installation requirements for this unit?
This is a substantial piece of equipment and installation planning should begin well before delivery. You will need a confirmed gas supply connection (natural gas or LPG), a correctly positioned grease extract canopy, and a floor capable of supporting the unit's weight. A qualified gas engineer is required for commissioning, and a ventilation specialist will typically be needed to sign off the extract setup. Access routes and doorway clearances should also be checked in advance given the unit's overall dimensions.
How does the iCombi Classic handle cooking consistency across a full twenty-grid load?
The unit uses multiple fan wheels to distribute heat evenly across all twenty levels, which addresses one of the common failure points in lesser combi ovens where results on outer or lower shelves diverge from those in the centre. Combined with the ClimaPlus humidity control system, this supports reproducible results batch to batch — an important consideration in high-volume operations where consistency across shifts matters as much as output speed.
