Rational iCombi Classic 6-2/1 Gas Combination Oven

The Rational iCombi Classic 6-2/1 is a large-format gas combination oven built for sustained, high-volume production. Operating in a six-level 2/1 GN configuration, it accommodates two 1/1 GN pans per shelf in landscape orientation, giving kitchen teams meaningful throughput across every service period. It runs across steam, convection and combination modes, with precise climate control handled through Rational's ClimaPlus system, which allows humidity adjustment in 10% increments. The result is a unit that can cycle through proteins, baked goods and vegetables within the same service without compromising consistency on any of them.

In busy kitchens, even heat distribution matters as much as raw capacity. Up to three fan wheels work with the cabinet geometry to circulate air evenly across a full load, which reduces the risk of hot spots and uneven cooking when the oven is running at capacity during peak service. The ClimaPlus climate management actively responds to the moisture content inside the chamber, which takes much of the manual adjustment out of the process and supports consistent results across different members of the kitchen team.

From a day-to-day operational standpoint, the iCombi Classic offers several practical advantages worth noting:

• Up to 100 stored programmes with multi-step processes of up to 12 steps, supporting consistency across varying skill levels
• Dial-and-push interface with colour display and clear symbols, keeping the learning curve manageable for new staff
• High-intensity LED chamber lighting for quick visual checks without opening the door mid-cook
• Automatic cleaning system with overnight capability and phosphate-free tablets, reducing manual cleaning time
• Integrated scale prevention within the care cycle, which is particularly relevant in hard-water areas

As a 2/1 GN gas unit of this size, installation demands careful planning. A commercial extraction canopy rated for gas cooking equipment is a standard requirement. The unit's footprint and weight are considerable, so floor loading capacity, delivery access and door-swing clearance should all be assessed before the unit arrives on site. Gas connection — whether natural gas or LPG — must be carried out by a Gas Safe registered engineer, and the kitchen layout should allow adequate clearance for pan loading and door operation without compromising workflow.

This model is well suited to hotel kitchens, contract catering facilities, central production units, banqueting operations and large restaurant groups where high-volume, multi-mode cooking is a daily requirement. For smaller, single-site operations with moderate covers, a lower-capacity unit within the iCombi Classic range is likely to be a better operational and financial fit. For sites with exceptionally high throughput demands or more complex production requirements, it is worth exploring whether a different model within the broader Rational range would be more appropriate.
