Description
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 15
0°F (65°C).Features
Construction

 A - Twin 16 AWG Copper Buss Wires — Provide reliable electrical current capability.
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.

electrically insulates the matrix and buss wires and 
provides resistance to water and some inorganic 
chemical solutions.

(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.
