Rational iCombi Classic 10-2/1 Gas Combination Oven

The Rational iCombi Classic 10-2/1 is a full-size gas combination oven capable of running twenty 1/1 GN pans simultaneously, loaded two per shelf in landscape orientation. It operates across three cooking modes — steam, convection and combination — and is available configured for either natural gas or LPG, making it adaptable to sites where mains gas is not available. This is a serious piece of production equipment, not a light-duty unit, and it warrants careful consideration before purchase.

In practice, the iCombi Classic is well suited to kitchens producing large volumes of food across multiple covers or service periods. The combination mode allows operators to balance heat and humidity simultaneously, which reduces cooking times and helps maintain consistency across a full rack. Rational's ClimaPlus humidity management allows cabinet humidity to be adjusted in 10% increments, giving chefs meaningful control over moisture levels for different menu items. Up to three fan wheels distribute heat evenly across the cavity, which matters considerably when running a full load during peak service. Results are reproducible: the oven supports up to 100 saved programmes with multi-step cooking sequences of up to 12 steps, so trained and untrained staff alike can replicate outcomes reliably.

From an operational standpoint, the iCombi Classic addresses a number of practical kitchen concerns:

• Reproducible results across shifts through saved multi-step programmes
• Precise humidity control reduces guesswork and improves consistency
• LED chamber lighting makes it straightforward to assess food without opening the door
• Automatic cleaning cycles, including an overnight option, reduce manual effort and use phosphate-free tablets
• The integrated care system helps manage scale build-up, which matters in hard-water areas

Installation requires a gas supply appropriate to the configured fuel type, along with adequate ventilation — either a canopy or a Rational-compatible ventilation hood. The unit is substantial in size and weight, so access routes and floor loading should be assessed before delivery. A water supply and drain connection are also required for steam generation and the automatic cleaning system. This is not a plug-and-play unit; professional installation by a qualified gas engineer and, ideally, a Rational-approved commissioning engineer is strongly advisable.

The 10-2/1 configuration is best suited to high-volume operations: large restaurant kitchens, hotel banqueting, contract catering, staff dining, and central production facilities where throughput demands are consistent and significant. For smaller operations or sites with lighter production requirements, a smaller rack configuration is likely to be more appropriate and more economical to run. Equally, sites with particularly demanding output volumes may want to consider a higher-capacity model or multiple units.

A combi oven at this level is a long-term operational decision, and getting the specification right from the outset saves considerable difficulty later. If you would like to talk through whether this model is the right fit for your kitchen, the team is happy to work through the details with you.
