Based on their solid knowledge of thermal processes, high temperature technology and compatibility of materials, the brothers Prof. Dr. Teja Retz (chemist) and Dr. Roland Reetz (physicist) established the owner-managed family enterprise in 1992, initially with only a few employees.

During their own research work, they sometimes themselves faced the problem that there was no suitable equipment for their specific applications available,  in particular in the high temperature range. From the very beginning till today ‒ after more than 25 years of existence ‒ it has been HTM’s particular aim to develop user-oriented solutions for research and science and to transfer them into efficient systems suited for various thermal processes. Already during the first years of its existence, HTM produced a variety of “standard” as well as innovative custom-made products.

The company would not have achieved this success if it had not been for the customers and their close and trusting co-operation with us. They appreciate very much our capabilities combined with many years of experience, creativity and high flexibility in helping them to find solutions for their specific problems.

Our central focus is always on the client and their wishes and requirements. Our highly qualified and experienced staff provide competent and reliable support, from the initial consultation to installation, commissioning and service work.

We pay particular attention to our production meeting high environmental and quality standards. High quality materials and workmanship are important to us. No product leaves our premises without being tested on our in-house test stand.
