The BARTEC EMK heating circuits have the main characteristics that they are extremely robust and mechanical loadable. Additional advantages of the laser welded heating circuits are the suitability for highest operating temperatures and the good chemical resistance.
Typical applications are frost protection, maintaining temperature and heat-up for example in pipes, tanks, pumps, valves and vessels.


The application of a supply voltage to the resistance cable generates heat. The quantity of heat is dependent on the resistance value of the heating cable and the supply voltage.
