Chromalox Thermwire Wrap provides safe reliable freeze protection for commercial and residential piping. Use anywhere pipes are exposed to subfreezing temperatures. Thermwire Wrap cables are flexible, can be cut to length in the field, and can be single overlapped without fear of burnout in areas where piping and equipment require additional heat trace cable. Chromalox manufactures self-regulating heating cables for use with 120V or 208-277V. Equipped with a grounding braid for electric code compliance, Thermwire Wrap cables are third-party tested and approved for use in commercial and residential applications on both metal and plastic pipes.


  • Metal Pipe Freeze Protection in Commercial or Residential applications
  • Plastic Pipe Freeze Protection  in Commercial or Residential applications

WARNING — A ground fault protection device is required by NEC to minimize the danger of fire if the heating cable is damaged or improperly installed. A minimum trip level of 30mA is recommended to minimize nuisance tripping.
