About us

The two brothers Prof. Dr. Teja Reetz and Dr. Roland Reetz founded with only a few employees in 1992, the owner-managed family business based on their solid knowledge of thermal processes, high-temperature technology and material compatibility.


HTM Reetz stands for High Temperature Materials
of the family business Reetz.

Especially for use in research, teaching and development, but also for smaller pilot plant and industrial applications, the company produces its own tailor-made high-temperature equipment for working at high temperatures (up to 3,000 °C) and in a wide variety of atmospheres. 
In addition to standard products, HTM Reetz GmbH primarily offers customized individual solutions.

Our range of services includes the repair service for furnaces, simulations of processes in large-scale plants as well as contract work in our in-house pilot plant station and much more. We are a competent team of 17 employees, 9 of them with university, college or technical college education, who will gladly assist you with their many years of professional experience.

Our strengths lie in solid knowledge and experience

  • on material compatibility at high temperatures;
  • in handling a wide variety of heating systems, defined atmospheres and vacuum systems;
  • to link temperature, gas flows and movements for the control of complex systems.

We are also familiar with many technological processes and procedures that help us to understand the concerns of our customers and implement them accordingly.
