Rational iCombi Classic 20-2/1 Electric Combination Oven

The Rational iCombi Classic 20-2/1 is a large-format electric combination oven designed for high-volume commercial kitchen environments. It operates across three cooking modes — steam, convection, and a combination of both — giving kitchen teams precise, independent control over temperature, humidity, and airflow within a single unit. The 20-2/1 configuration is one of the largest in the iCombi Classic range, and represents a serious capital commitment that warrants careful specification before purchase.

In a demanding service environment, consistency across a fully loaded cabinet is what separates a well-specified combi oven from one that struggles under pressure. The iCombi Classic uses multiple fan wheels working in conjunction with the cooking chamber geometry to circulate heat evenly across all levels simultaneously. The ClimaPlus humidity control system allows fine adjustment of the cooking climate, which in practice means kitchen teams can move between roasting, steaming, and regeneration without significant recovery time between loads. Door-opening recovery is reliable — an important consideration when multiple chefs are loading and unloading continuously during a busy service.

From an operational standpoint, the iCombi Classic is built to reduce the margin for error across shifts and skill levels:

• Up to 100 programmable cooking sequences, each with up to 12 steps, support consistency across the team
• Rotary dial with push function and colour display keeps the interface accessible under service pressure
• Automatic overnight cleaning cycle with phosphate-free tablets reduces morning preparation time
• Integrated descaling within the care programme helps protect internal components over time
• High-intensity LED chamber lighting allows visual monitoring without opening the door

At this scale, installation planning is essential before ordering. The unit is large and heavy, requiring a clear delivery route and adequate floor space. As an electric model, a suitable three-phase power supply is required — your electrician and Rational's installation guidelines should both be consulted early in the process. Ventilation requirements are considerable, and a correctly specified extraction canopy should be confirmed with your kitchen installer. Water connection and drainage are also required for steam generation and the integrated cleaning functions.

The 20-2/1 iCombi Classic is well suited to large-scale operations where throughput justifies the footprint and capital investment — central production kitchens, large contract catering sites, stadium and event catering, and high-volume institutional or hotel operations. For kitchens with more moderate output or tighter space constraints, smaller configurations within the iCombi Classic range are worth considering. For operations that need greater automation or connected kitchen functionality, Rational's iCombi Pro series is worth exploring as part of any specification conversation.

If you're working through the right size for your operation, confirming power and ventilation requirements, or comparing configurations, the team is happy to work through the detail with you before anything is decided.
