Process Temperature Maintenance or Freeze Protection
High performance VSX self-regulating heating cables are designed specifically for process temperature maintenance or freeze protection where high maintain temperatures or high temperature exposure are required.

The heat output of VSX cable varies in response to the surrounding temperature by reducing its thermal output with increasing temperature. With its high self-regulating characteristic, VSX can be installed in hazardous areas requiring a T3 temperature class rating.

VSX cables are approved for use in ordinary (non-classified) areas, Division 2 classified areas, and Zone 1 and 2 Classified areas.
