An investment that pays off.

It really pays to have a SelfCookingCenter® in your kitchen. You save energy, water, time, and raw materials, and have less waste. You’ll also enjoy up to 30% more kitchen space, because one small RATIONAL appliance can free up or replace 40 to 50% of all standard cooking appliances.

whitefficiency® is our contribution to sustainability, a contribution that begins right from the product development phase. We work in close collaboration with universities to find solutions that save on resources. This policy also manifests itself in the company's environmentally certified production, in our energy efficient sales logistics and in the return and recycling of our old appliances.
