History.
Milestones in an extraordinary company history.

Maximum possible benefits for our customers: This has been our aim for over 40 years now.
It all began with the idea of combining steam and convection into a single appliance. In 1976, we therefore developed our first combi-steamer and have since been constantly working on continuously improving it.
