Description

Typical applications are frost protection, maintaining temperature and heat- up in pipes, tanks, vessels or at surfaces in non-ex areas and in explosive atmospheres for process industry. The BARTEC electric trace heating system type PSB offers the optimum solution for requirements following II2G Ex e II T5, T6 und II2D Ex tD A21 IP65 T95?C, T80?C.

The self-limiting heating cable type PSB is available with various nominal power ratings from 10W/m to 33 W/m at 10 ?C (maximum admissible work-piece temperature of +65?C, power ON and +85?C power OFF, cumulative 1000h). The standard outer insulation jacket is made of polyolefin or optionally of a fluorine polymer plastic for special applications which require chemical resistance and mechanical strength. Dependant on the cut-in temperature and respectively the cut- in current and the supplied voltages a maximum heating circuit length about 200m is possible.
