VSX-HT™ Self-Regulating Heating Cable

High performance VSX-HT self-regulating heating cables are designed specifically for process temperature maintenance or freeze protection applications where high maintain temperatures or high temperature exposures are required. The heat output of VSX-HT cable varies in response to the surrounding temperature by reducing its thermal output with increasing temperature. VSX-HT cables can be installed in hazardous and Zone 1, 2, 21, and 22 areas.


  • Freeze protection
