The core competence of DELLER Safety Heat Exchangers is the construction of safety heat exchangers for applications in the chemical and pharmaceutical industry. In this field, we have many years of experience as well as lots of unique selling points.
More than 90 years ago, on April 1, 1926, Wilhelm Haub and Wilhelm Deller made the decision to invest their savings into the foundation of their own company. This marks the birth of the Wilhelm Deller GmbH & Co. KG in the south-westphalian Kreuztal-Buschhhütten.
The experience of both our founders in steel sheet processing was initially implemented in the manufacture of smaller tanks. Shortly after, the young company moved to their own workshop in Sohlbach near Siegen – already with 20 employees. This is where, in 1948, the first heat exchangers were manufactured. Over the last 50 years, the company evolved into the leading provider for safety heat exchangers.
Today, partners and customers profit from high-quality heat exchangers and thermal instruments that are individually catered to the requirements of the respective environmental variables.
