Rational iCombi Classic 20-2/1 Gas Combination Oven

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.
