History

In 1976, Rational introduced their first combi-steamer to the public after having the idea of combining the functions of a commercial steamer with those of a convection oven into one appliance.

In 2004, Rational invented their original SelfCookingCenter, a multi-functional cooking appliance that allowed users to select the type of food being cooked and its desired results without having to enter complicated time, temperature, and humidity settings. The appliance could also manually cook with convection, steam, and combi-steam and be programmed with additional presets.

Today, Rational has over 50% of the global market share for multi-functional appliances and their products can be found in over 100 countries worldwide.
