Dejatech’s history goes back to 1970. Founder Jan Deckers, inventor of the modern boiler, was the first in Europe to market an aluminium heat exchanger for the boiler. An innovative breakthrough for its time that immediately made gas heating much more energy efficient. Now, after nearly 50 years, Jan Deckers is still associated with Dejatech as a consultant.

This rich history is a good breeding ground to build on. Dejatech’s technicians, professionals and experts continue to lead in the field of heat exchangers, heat engines and hybrid systems. Our patents ensure sustainable and environment-friendly comfort at your home and work. We deliver this in Europe and far beyond.
