Frost Protection Trace Heating Cables

Trace Heating cable

frost protection

Chromalox SRF frost protection trace heating cables provide self-regulating freeze protection to institutional buildings and freeze protection applications up to 185º F with CSA and UL certification – UL listed for ordinary areas and fire protection system piping, CSA certified for ordinary areas.

Trace Heating Cable Features

  • Energy efficient SRF frost protection cables require less energy as less heat is required
  • Simple to install trace heating cable and can be cut to any length (see max circuit length)
  • Heating cables can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
  • Field splices can be performed easily in minutes with no scrap or wasted cold sections
  • Chromalox termination, splice, tee and end seal kits reduce installation time of the trace heating systems

Chromalox Frost Protection Cable

Construction

  • A Twin 16 AWG Copper Buss Wires are able to provide reliable electrical current capability.
  • B Semiconductive Polymer Core Matrix is the ‘self regulating component of the cable and it’s electrical resistance varies with temperature.
  • C Fluoropolymer Jacket is flame retardant and electrically insulates the matric and buss wires and provides corrosion resistance.
  • D Tinned Copper Braid that provides additional mechanical protection in any environment, and a positive ground path for the heating cables
  • E High Temperature Fluoropolymer or TPR Overjacket (optional) is a corrosion resistant, flame retardant overjacket is highly effective in many environments. TPR coatings protect against certain inorganic chemical solutions.
