  • Fluid Flow, Transfer & Viscosity Maintenance

Chromalox SRP Self-Regulating Trace Heating Cable


  1. Twin 16 AWG Copper Buss Wires are able to provide reliable electrical current capability.
  2. Semiconductive Polymer Core Matrix is the self regulating component of the cable and it’s electrical resistance varies with temperature.
  3. Fluoropolymer Jacket is flame retardant and electrically insulates the matrix and buss wires and provides corrosion resistance.
  4. Tinned Copper Braid that provides additional mechanical protection in any environment, and a positive ground path.
  5. High Temperature Fluoropolymer Overjacket (optional) is a corrosion resistant, flame retardant overjacket which is highly effective in many environments. It protects against exposure to organic or corrosive solutions as well as abrasion and impact damage.
