Self-regulating Heating System


self-regulating electric heat trace cable

features a heating element with PTC properties between the two connections, permitting a lower flow of electric current at higher temperatures, thus reducing the power output in self-limiting manner

suitable as frost protection as well as to maintain process temperatures up to 150 °C, intermittently up to max. 250 °C, e.g. during steam cleaning

The Main Features:

temperature-dependent power output

connecting voltage 230 to 277 V

easy handling

lengths adjustable nearly infinitely

useable in explosion-endangered areas
