Providers of heat and energy systems
-worldwide

In almost 20 years of operation, Classen Apparatebau Wiesloch has made a name worldwide for high-quality, individually tailored plants in the sector of high temperature process heating. We are specialists in engineering, construction and commissioning of complete plants for heat generation, heat storage and heat distribution in the temperature range up to and above 400 °C.

1967 – 1989 Apparatebau Wiesloch

Up to the early 90s, the name represented a leading company in the production of high-temperature heating systems. Wiesloch“ had sold about 4,000 thermal oil heaters all over the world, including heaters for maritime use, wood-fired plants and plants using liquid and gas fuels.

1989 – 1992 Kraftanlagen Heidelberg (KAH)

The production facilities remained in operation with a new owner and continued to fabricate heaters and equipment parts for KONUS-Kessel and several other companies.

1993 – 1997 IRSM

In the same place the company IRSM fabricated thermal oil and auxiliary installations for KONUS-Kessel and the successor Betrams-KONUS as well as for other companies.

1998 – until today

Norbert Classen (previously CEO of Bertrams-KONUS), Claus Albrecht (previously authorized officer of Bertrams-KONUS) and Hans-Raymund Roos (previously commercial director of Bertrams-KONUS) founded the company Classen Apparatebau Wiesloch (CAW“) in 1998, to resume the direct sales of Wiesloch-products and equipment.
