Rational iCombi Classic 20-2/1 Electric Combination Oven

The Rational iCombi Classic 20-2/1 is a full-size electric combination oven designed for high-volume commercial kitchens. It operates across three cooking modes — steam, convection, and combination — giving kitchen teams full control over temperature, humidity, and airflow within a single unit. The 20-2/1 format accommodates twenty 2/1 GN pans arranged in landscape orientation, making it one of the largest models in the iCombi Classic range and a serious piece of kit for operations cooking in volume.

In a busy service environment, the ability to load the cabinet to full capacity and still achieve consistent, even results is what distinguishes a well-specified combi oven from an underpowered one. The iCombi Classic uses multiple fan wheels working in concert with the cooking chamber geometry to circulate heat evenly across all levels simultaneously. The ClimaPlus humidity control system allows precise adjustment of the cooking climate in measured increments, which in practice means operators can move between roasting, steaming, and regeneration without compromising food quality or requiring significant dwell time between loads. Recovery after door opening is dependable, which matters when multiple chefs are loading and unloading at pace.

From an operational standpoint, the iCombi Classic is built to reduce the margin for error during service:

• Up to 100 programmes with multi-step cooking sequences of up to 12 stages, supporting consistent results across different shifts and skill levels
• Rotary dial with push function and colour display keeps the interface accessible under pressure
• Automatic overnight cleaning cycle with phosphate-free tablets reduces morning prep burden
• Integrated descaling within the care system helps protect internal components over time
• High-intensity LED lighting in the cooking chamber allows monitoring without opening the door

Installation of a unit at this scale requires careful planning. This is a large, heavy appliance that will need adequate floor space and a clear service route on delivery. As an electric model, it requires a suitable three-phase power supply — your electrician and Rational's installation guidelines should be consulted before ordering. Ventilation requirements are significant at this capacity; a properly specified canopy or ventilation system should be confirmed with your kitchen designer or installer. Water connection and drainage are also required for the steam and cleaning functions.

The 20-2/1 iCombi Classic is best suited to high-volume operations — large contract catering sites, central production kitchens, stadium and event catering, and large hotel or institutional kitchens where throughput demands justify the footprint and capital outlay. For kitchens with more moderate volumes or tighter space constraints, smaller configurations in the iCombi Classic range are worth considering. For operations that need more automation or advanced connected features, Rational's iCombi Pro series may be worth exploring alongside this model.

If you're weighing up whether the 20-2/1 is the right size for your operation, or have questions about power requirements and installation, the team is happy to talk it through with you before you commit.
