Working with independent scientific institutions, we continuously refine the HAT System. In the process, we subject it to the most stringent tests and examinations. The most recent example: our collaboration with the HTA, the Lucerne College of Engineering and Architecture. In cooperation with specialists from the institute, we have developed a method for analysing the degree of embrittlement in plastic pipes. Furthermore, the effect on heat flux density was compared between new plastic pipes and those coated with the HAT System.
The result is pleasing: our system provides optimum material properties. And the research goes on.
