Inspiringly different.

It all began with the idea of combining steam and convection cooking into a single appliance. So we developed our first combi-steamer in 1973, and we have been continuously working to improve it ever since. Yet our company has never just been content with being a mechanical engineer. We see ourselves as an innovative solutions provider. Above all else, our utmost priority is to satisfy our customers.

This vision has transformed RATIONAL into a global market and technology leader. RATIONAL products are an integral part of industrial kitchens.

With over 1,200,000 RATIONAL appliances on the market, our appliances have become a standard in professional kitchens all over the world. And what we're particularly happy about: 93% of our global customers confirm that RATIONAL offers maximum customer benefit. (TNS Infratest 2016 study). Definitely one reason why almost all of them would also recommend RATIONAL.
