About Rational Ovens
Rational is a global leader in combi-steamer technology, combining steam, convection and combination cooking modes in a single unit to replace multiple pieces of cooking equipment on a busy line.
We supply, install and support Rational combi ovens for hotels, restaurants and central kitchens that need consistent, repeatable results across steaming, roasting, baking and regeneration in one footprint.
Multi-mode versatility
One unit handles steaming, roasting, baking, grilling and low-temperature cooking, reducing the number of separate appliances a kitchen needs.
Consistent, repeatable output
Precise humidity and temperature control means the tenth tray comes out matching the first, even during a busy banquet service.
Core temperature precision
A probe accessory monitors the centre of large cuts, so meat and bulk dishes finish exactly to target doneness.
Automated cleaning cycle
Built-in cleaning programs cut down on manual scrubbing and help maintain hygiene standards between services.
Energy-conscious operation
Combi cooking technology is engineered to reduce energy and water use compared to running multiple separate appliances.
