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.
We know how important a clear and comprehensible explanation of our services is – even in the very first stages of preparing an offer. We don’t hide any expenses in specialist terms and communicate clearly and proficiently.
Because we know how crucial efficient and economical apparatuses are in the everyday plant operations of our customers, we include modern and innovative technology in our products.
We believe that a transparent communication that quickly answers pending questions settles any doubts, makes for solutions, and contributes to a good relationship and an even better cooperation.
Due to our integration in the ZILONIS corporate group we can access a large, technologically conscious and innovative network of suppliers and logistics operations. Our customers profit from this as well.
Our internal guiding principle demands and promotes the application of modern technology, which minimizes the ecological footprint in our and our customers’ companies.
With this in mind we engage in current research projects. We embed these sustainable experiences in our current projects, by which means one can operate our products more efficiently and economically.
