The quality of our products, their efficiency and environmental
safety are all of equal importance to us and all environmental

Packaging
We participate in the recycling programmes of the countries in
which our products are sold to ensure optimum recycling.
All of our packaging materials are environmentally friendly and

Used appliances
Used appliances contain valuable materials that should be
recycled.
The various assemblies can be easily dismantled and synthetic
materials are marked accordingly. Assemblies can therefore be
sorted by composition and passed on for recycling or disposal.
