Chromalox SRME | SRM/E Self-Regulating Medium Temperature


  • Energy efficient, self-regulating SRM/E uses less energy when less heat is required.
  • Easy to install, SRM/E can be cut to any length (up to max. circuit length) in the field.
  • Field splices can be performed easily in minutes with no scrap or wasted cold sections.
  • With lower installed cost than steam tracing, SRM/E features less maintenance expense and downtime.
  • SRM/E can be overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
  • Because SRM/E is self-regulating, overtemperature conditions are minimized.
  • Chromalox termination, splice, tee and end seal kits reduce installation time.

Chromalox SRM/E self-regulating heating cable provides safe, reliable heat tracing for process temperature maintenance and freeze protection of pipes, valves, tanks and similar applications. Constructed of industrial grade 16 AWG buss wire with metal braid and optional overjacketing, SRM/E ensures operating integrity in most hostile industrial environments. The 420°F (215°C) maximum exposure temperature rating allows steam cleaning of process equipment with up to 300 psig steam.

A.  Twin 16 AWG Copper Buss Wires — Provide reliable electrical 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. High-Temperature Fluoropolymer Jacket — Flame retardant, electrically insulates the matrix and provides corrosion resistance.

D. Metallic Braid — Provides additional mechanical protection in any environment and a positive ground path.

E. High-Temperature Fluoropolymer Overjacket — Corrosion-resistant, flame retardant overjacket is highly effective in hostile, aqueous and chemically active environments. It also protects against abrasion and impact damage.
