More than a Century of Air-Conditioning Expertise – Eberspaecher Sütrak

Wilhelm Weckerle establishes Sümak, shortened from "Süddeutsche Maschinen- und Metallwarenfabrik" (English: South German machine and metal work company), which manufactures commercial refrigerators and compressors in Stuttgart, Germany.

In the 30s
Production of transport air-conditioning systems begins.

The first bus air-conditioning system is developed.

Using a "Sümak" refrigeration system, the world's first cooled bobsled and toboggan run is built in Königssee-Berchtesgaden, in southern Bavaria.

The mobile refrigeration and air-conditioning systems division is branched off. Sütrak is founded as a new company. Mass production of bus air-conditioning systems begins.

In the 80s
The company's global expansion continues with strong growth in the bus air-conditioning sector. The new headquarters in Renningen, near Stuttgart, is opened.

The Carrier Corporation, the world's largest supplier of air-conditioning and refrigeration equipment acquires the "Sütrak" business.

Eberspaecher acquires Sütrak's bus AC business in Europe, the Middle East and Africa from the Carrier Corporation. Eberspaecher Sütrak's Renningen location becomes a center of expertise for "bus air-conditioning and heating systems."
