Typical applications are frost protection, temperature maintenance and heat-up in pipes, tanks, vessels or surfaces. The electric trace heating system HSB offers the optimum solution for Zone 1, 2, 21 and 22 as well as Class I Div 2, Class II and III. The self-limiting heating tape HSB is available with various nominal power ratings from 10 W/m to 60 W/m at 10 °C. The outer insulation jacket is made of fluoropolymer for special applications which require chemical resistance and mechanical strength. Dependant on the start-up temperature, the start-up current and the supply voltage a maximum heating circuit length of 235 m is possible.
