The history of Apparatebau Wiesloch began as early as the end of the 1960s. The technical advantages of mineral heat transfer oils over steam - in particular virtually pressureless plant operation at operating temperatures of up to approx. 350 °C - lead to increasingly widespread use of this technology worldwide. Already at this time, a comprehensive product portfolio is developed around the successful KONTAKTOMAT® three-pass heater fired with fuel gases and fuel oils and manufactured in Wiesloch: Electric heaters, process heat exchangers, systems for thermal exhaust air purification, steel chimneys, waste heat recovery systems and cleaning equipment. After only a few years, "plants from Wiesloch" are already operating in over 40 countries. At the beginning of the 1990s, the business operations of Apparatebau Wiesloch GmbH are discontinued.
Then, in 1998, a completely new era begins: Norbert Classen, Claus Albrecht and Hans-Raymund Roos found the company Classen Apparatebau Wiesloch GmbH, after almost 23 years on the market, gladly called "CAW" by customers and business partners all over the world, to resume worldwide direct sales of the popular and proven Wiesloch products.
