Chromalox SRP Self-Regulating Process Temperature


  • Energy-efficient, self-regulating SRP uses less energy when less heat is required.
  • Easy to install, SRP can be cut to any length (up to max circuit length) in the field.
  • SRP features lower installed cost than steam tracing, less maintenance expense and less down time.
  • SRP can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
  • Because SRP is self-regulating, over-temperature conditions are minimized.
  • Chromalox U-Series Connection Kits reduce installation time.

Chromalox SRP self-regulating heating cable provides safe, reliable heat tracing for process maintenance applications to 230°F (110°C) or freeze protection of pipes/tank with high heat losses. Constructed of industrial grade 16 AWG buss wire with a tinned copper braid and optional overjacketing, SRP ensures operating integrity most hostile industrial environments.

A.  Twin 16 AWG Copper Buss Wires – Provide reliable electric current capability.

B. Semiconductive Polymer Core Matrix “Self-Regulating” component of the cable its electrical resistance varies with temperature. As process temperature drops, the core’s heat output increases; as process temperature rises, the heat output decreases.

C. Fluoropolymer Jacket – Flame retardant, electrically insulates the matrix and buss wires and provides corrosion resistance.

D. Tinned Copper Braid – Provides additional mechanical protection in any environment and a positive ground path.

E. High-Temperature Fluoropolymer OverLow Temperature Self Regulating Output Temperature Output Cut to Length in Field Can be Single Overlapped Maintains up to 230°F Withstands up to 275°F jacket – Corrosion-resistant, flame retardant overjacket is highly effective in many environments. Protects against exposure to organic or corrosive solutions. The overjacket also protects against abrasion and impact damage.
