Chromalox SRL 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 optional overjacketing, SRL ensures operating integrity in Div. 2 hazardous environments as well as certain corrosive industrial environments. SRL heating cable has a maximum maintenance temperature rating of 150°F (65°C).

• Energy efficient, self-regulating SRL uses less energy when less heat is required.
• Easy to install, SRL 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.
• SRL features lower installed cost than steam tracing, less maintenance expense and less downtime.
• SRL can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
• Because SRL is self-regulating, over-temperature conditions are minimized.
• Chromalox termination, splice, tee and end seal kits reduce installation time.

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 - 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 or TPR Overjacket (optional) — Corrosion resistant, flame retardant overjacket is highly effective in many environments. TPR coatings protect against certain inorganic chemical solutions. Fluoropolymer coatings are used for exposure to organic or corrosive solutions. These coatings also protect against abrasion and impact damage.

SRL3-1C

Note: The SRL cable is sold by the foot and therefore a custom order.  Once the order is placed it cannot be cancelled or returned once you receive the cable.  This is because the cable is cut to length here, or at Chromalox, for your order, from your requested length.
