Typical applications are frost protection, temperature maintenance and heat-up in pipes, tanks, vessels or surfaces in non-ex areas and in explosive atmospheres for process industry. The electric trace heating system PSB is the perfect solution in Zone 1, 2, 21 and 22 as well as Class I, II and III Div 2.

The self-limiting heating tape PSB is available with various nominal power ratings from 10 W/m to 33 W/m. The standard outer insulation jacket is made of polyolefin. For special applications which require chemical resistance and mechanical strength a fluoropolymer insulation-jacket is optionally available. Dependant on the start-up temperature respectively the start-up current and the supplied voltages a maximum heating circuit length of 200 m is possible.
