1. General information
Bartec PSB heating type is suitable for electric trace heating for frost protection of pipelines and vessels, while the polyolefin protective jacket is used where there are aqueous, inorganic chemicals, the fluoropolymer protective jacket is suitable for organic chemicals.PSB can be used in explosive atmospheres without temperature limiter and be cut at random length thanks to its parallel current supply; corrosion-proof and resistant to effects of chemicals thanks to its outer sheath; electrically and mechanically protected by a tinned copper braiding.
Simple installation thanks to its high flexibility and favorable dimensions. A temperature-dependant resistive element between two parallel copper conductors regulates and limits the heat output of the heating tape according to the ambient temperature. If the ambient temperature rises, the power output of the heating tape is reduced. This self-limiting property prevents overheating even when the tapes are crossed. A temperature limiter is not necessary (also not in hazardous areas). Thanks to the parallel design the heating tape can be cut and installed to any required length. The self-limiting heating tape is available with different power outputs and protective jackets. The protective outer jacket of either fluoropolymer or polyolefin protects the copper braiding from corrosion and chemical impact. Two jackets under the protective braiding provide electrical insulation. The inner one of the two jackets is thermally fused to the heating element (bonded jacket).
