We are your Swiss quality manufacturer

  • for sustainable and efficient air-conditioning, cooling and heating

  • high-quality products using renewable energies

Located in Switzerland

From mass-produced industrial heat pumps to standardised domestic heat pumps, we develop, manufacture, install and test environmentally friendly heating systems and chillers at our headquarters in Münsingen, Bern. That’s our contribution to the renewable energy transition. And it’s our contribution to Switzerland as a workplace.

Environmentally responsible

Not only our products, but also our actions should be environmentally friendly. As much as possible, we use sustainable materials and ensure that waste is properly separated and disposed of in the right way. We promote the use of natural and climate-friendly refrigerants and are careful in our use of natural resources. We obtain most of the energy for our production in Münsingen, Bern from our rooftop photovoltaic system. Our premises are heated with air source and ground source heat pumps.
