ThermoTEC attaches great importance to close cooperation with the nearby Weilburg Technical Academy to counter the ever growing demands of the market. Internal training courses as well as external further education, such as at the Bundesfachschule Kälte-Klima-Technik (Federal College of Refrigeration and Air Conditioning Technology) in Maintal, from the cornerstone in meeting our quality standards.

The in-depth expertise of our employees is enhanced by high-quality products, such as the temperature and humidity testing chambers of ESPEC Corp. in Japan, one of the world`s leading providers of environmental simulation equipment.

Test chambers from ESPEC are used in many branches of industry, such as the automotive, electronics and semiconductor sectors as well as in the aerospace industry – wherever material and function tests in reproducible environmental conditions are performed.

We focus on the highest quality – not only in our products. ThermoTEC has been certified in accordance with ISO 9001 since 2003.

In order to always also meet the current demands of the market as a calibration service provider, since 2015 we have maintained an accredited calibration laboratory in accordance with ISO 17025 for the physical parameters of temperature and relative humidity. This permits ThermoTEC to calibrate temperature test chambers and climate test chambers, thermal shock test chambers, ovens as well as other environmental simulation systems, independent of the manufactuerer, on site.
