Hi. We are CTA.
With heat pumps, air-conditioning units and chillers, we ensure that the temperature and climate are right – for people and for nature. As an independent, family-run, Swiss company with more than 200 employees, we have been committed to renewable energies and energy-efficient system solutions for heating and cooling buildings since 1981.
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. EnAW Certificate [↗]
