RATIONAL Combi Ovens & Cooking Systems
RATIONAL is a German manufacturer based in Landsberg am Lech, founded in 1973. It is best known for the combi steamer, which it introduced in 1976, and today builds the iCombi Pro combi oven and the iVario multifunction cooking system.
How kitchens use RATIONAL equipment
A combi oven replaces several appliances by combining dry heat and steam: it can roast, bake, steam, braise and hold in one cabinet. Hospitals and universities use roll-in 20-pan models for high volumes, while restaurants and hotels often choose 6-pan or 10-pan units. The iVario cooks with direct contact heat and is used for frying, boiling and pressure cooking.
U.S. versions and site requirements
RATIONAL offers U.S. models in 208/240V and 480V three-phase versions, and gas models for natural gas or propane. Before ordering, check the electrical service, gas type, water quality for steam generation and the ventilation your local code requires. Retailer listings for U.S. iCombi Pro models show UL and NSF listings; we confirm the exact listing for each model code.

Questions about RATIONAL
What size RATIONAL combi oven does my kitchen need?
Size depends on the number of meals and the menu. As a starting point, 6-pan units suit smaller kitchens, 10-pan units serve mid-size operations and 20-pan roll-in units serve high-volume kitchens. We help size the oven from your menu and meal counts.
Does RATIONAL warranty coverage depend on where I buy?
RATIONAL USA states warranty terms in its own warranty documents, including proof of purchase and installation. We explain warranty and commissioning arrangements in writing in every quote.
