APL Hopfgarten was founded in 1966 by Anton Pletzer under the name of "Stahlbau Hopfgarten", in the town of the same name in the Austrian Tyrol. Beginning in the 1980s, the company's own production of heat exchangers was developed; the factory hall dedicated to this product group began operation in 1996. On the basis of applications in the refrigeration industry, APL Hopfgarten developed in the 1990s into a leading manufacturer of heat exchangers, focussing particularly on the use of special materials.
Hans Güntner GmbH Dormagen was formed in 1979 from two companies (the former Rheinkälte GmbH Düsseldorf and Wassenberg GmbH Dormagen) with many years of experience in the design and production of shell-tube heat exchangers for the refrigeration industry and for chemical concerns operating in the area. As the years went by, applications were also found in the foodstuff industry and within general plant construction. Today APL Dormagen is one of Germany's leading equipment manufacturers, specialising in the construction and implementation in production of special applications for the chemical and petrochemical industries.
With the merger of two established equipment manufacturers: Apparatebau Hopfgarten GmbH and Hans Güntner GmbH in Dormagen.
