About us
Our history, employees, and customers.
Our mission is to make industrial processes efficient, reliable, and safe—with customized heat tracing and freezing protection systems, 100% manufactured in Germany.
We develop solutions that work, even under the most extreme conditions.
We rely on engineering expertise, high-quality in-house manufacturing, and a team that not only completes projects but also thinks proactively. Our aim is to create the optimal technical solution for every project—durable, sustainable, and customer-focused.

Our history
Pro Therm was founded in Dortmund in 1998 with the aim of rethinking trace heating technology.
With a team of experienced engineers, technicians, and organizational talents, we quickly developed into a provider that not only plans complex systems but also implements them holistically: from project planning to commissioning.
Our growth first took us to Castrop-Rauxel and later, with the integration of Schwarz+Fengler Wärmtechnik in 2015, to Waltrop.
Through the acquisition of Elektro Döring, we have specifically expanded our range of services and now also offer professional electrical installations.
Today, Pro Therm stands for technical expertise, modern manufacturing, and a team that passionately transforms challenges into solutions.
