A history of technical milestones in refrigeration

Friotherm has its roots in the Sulzer group and offers heat pumps, chillers, components and services of high quality and reliability. The company became legally independent by means of a management buyout in 2005.

Our heritage

In 1878 Sulzer bros. Winterthur started the construction of refrigeration plants as a logic expansion to their activities in the business fields "steam engines" and "compressors". At that time, refrigeration machines were huge and heavy, but nevertheless, in 1879 export commenced already. Friotherm retains and expands this heritage by developing industrial chillers and heat pumps to serve the ever changing needs of the industries.

Heat Pumps since 1936

In 1936, we installed World's first heat pump at the Zurich town hall. The plant is still in operating condition. Friotherm today successfully constructs heat pumps of large capacities for district heating-systems.

Todays Heat Pumps have to cool

In many cases, it is expected that a heat pump can simultaneously be used to supply a DH- as well as a DC-system. Friotherm Heat Pumps are designed "taylor made", in full accordance with client requirements. Thus, they are as flexible in operation a client may desire.

Sales and Service network

Todays sales and service network of Friotherm covers four branch offices in Brasil, Germany, France and Sweden as well as an office in China.
