Rational iCombi Classic 20-1/1 Electric Combination Oven

The Rational iCombi Classic 20-1/1 is a full-size, 20-grid electric combination oven designed for high-volume professional kitchens. It operates across three cooking modes — convection, steam, and a combination of both — enabling kitchen teams to roast, bake, steam, braise, and regenerate within a single unit. Up to 100 multi-step programmes can be stored, supporting consistent, repeatable results across different shifts without depending on individual operator knowledge.

In a demanding service environment, the ClimaPlus humidity management system is one of the more operationally significant features. The ability to set cabinet humidity in defined increments gives kitchen teams precise control over cooking conditions, which supports better product yield, more uniform finishes, and a reduced risk of overcooking during busy service periods. Multiple fan wheels distribute heat evenly across all 20 rack positions, so full-capacity loads perform as reliably as lighter ones — an important consideration when the oven is running at its limits during peak service.

The day-to-day operational advantages worth noting:

• Programmable multi-step cooking reduces reliance on experienced staff for consistent output
• Precise humidity control across cooking modes improves yield on a wide range of menu items
• Even heat distribution supports reliable results at full 20-grid capacity
• Automatic cleaning with phosphate-free tabs and integrated scale prevention
• High-intensity LED chamber lighting allows quick visual checks without opening the door

A unit of this size requires a three-phase electrical supply, adequate ventilation, and careful space planning — particularly around door swing clearance and tray extraction depth. A suitable stand or base unit will be needed unless the oven is being installed into an existing rack arrangement. Given the size, weight, and electrical requirements, a site survey before ordering is strongly advisable.

The iCombi Classic 20-1/1 is well suited to hotel kitchens, contract catering operations, central production units, hospital catering, and large restaurant kitchens where consistent high-volume output is a daily requirement. For operations where a 20-grid unit would rarely run at meaningful capacity, a smaller model within the iCombi Classic range is likely a more proportionate investment. For very large central production facilities with greater throughput demands, higher-capacity options exist within the Rational range.
