frost protection

Chromalox SRP self-regulating trace heating cables provide process temperature maintenance and frost protection to pipework, instrument lines, tanks and drums.

With UL Listing and CSA, ATEX, IECEx and FM certification Chromalox SRP heat trace cables are suitable for use in hazardous areas.

Heating Cable Features

  • Energy efficient SRP self regulating trace heating cables requires less energy as less heat is required
  • Simple to install heat trace cable and can be cut to any length (see max circuit length)
  • SRP trace heating cables offer low installation costs and require less maintenance minimising downtime
  • Heating cables can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
  • Chromalox U-Series Connection Kits reduce installation time

trace heating CABLE – SPECIFICATION

Construction

Chromalox SRP Self-Regulating Trace Heating 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.
  • E High Temperature Fluoropolymer Overjacket is a corrosion resistant, flame retardant overjacket is highly effective in many environments.
