Chromalox HSRL Self-Regulating Low Temperature


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

Chromalox HSRL self-regulating heating cable provides safe, reliable heat tracing for freeze protection of pipes, valves, tanks and similar applications. Constructed of industrial grade 16 AWG buss wire with a tinned copper braid and fluoropolymer overjacket, HSRL ensures operating integrity in Div. 1 hazardous environments. HSRL heating cable has a maximum maintenance temperature rating of 150°F (65°C) and a maximum exposure temperature of 185°F (85°C).

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. Polyolefin Jacket— Flame retardant, electrically insulates the matrix and buss wires and provides resistance to water and some inorganic chemical solutions.

D. Tinned Copper 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 many environments. Protects against exposure to organic or corrosive solutions. The overjacket also protects against abrasion and impact damage.
