Rational iCombi Classic 20-2/1 Gas Combination Oven

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

In a busy 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, which reduces the risk of uneven results when the oven is running at capacity. The ClimaPlus humidity management system allows the cooking cabinet climate to be adjusted in defined stages, giving cooks reliable control during complex or multi-step processes. Programmes can be saved and recalled consistently, which helps maintain results across shifts and reduces dependence on individual cook knowledge at peak times.

From an operational standpoint, the iCombi Classic offers a number of practical advantages for kitchen teams:

• Up to 100 saved programmes with multi-step cooking of up to 12 steps per process
• 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-term reliability
• High-intensity LED chamber lighting for visual checks without opening the door

The 20-2/1 is a substantial piece of equipment and warrants careful planning before installation. Gas supply, adequate ventilation and extraction must all be confirmed as suitable for a unit of this output before ordering. A professional installation is standard practice, and the physical footprint and weight mean 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 in the process, 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 operations with lower throughput requirements, 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 also produce models with a broader feature set worth considering.

A combination oven at this scale is a long-term commitment, and matching the specification carefully to your kitchen's actual volume and workflow avoids complications further down the line. We're happy to work through the detail with you — whether that's confirming the right capacity, talking through installation requirements, or helping you weigh this model against alternatives in the range.
