SELF-REGULATING HEATING CABLE/LOW TEMPERATURE SRL Series Starts at ߜ 3, 5, 8 and 10 W/ft ߜ 120 and 240V ߜ 65°C (150°F) Maximum Maintenance Temperature APPLICATIONS Standard Construction SRL self-regulating heating cable provides safe, reliable heat tracing for freeze protection of pipes, valves, tanks, and similar applications. The 65°C (150°F) maximum pipe maintenance temperature rating is also suitable for certain process applications. OMEGALUX® SRL can be used in hazardous as well as certain corrosive areas. He SRL3-1C, $5/ft, shown larger than actual size. A. Buss wires. Twin 16 AWG copper buss wires provide good current capability. B. Matrix. A semiconductive polymer core whose electrical resistance varies with temperature. When process temperature drops, the core’s heat output increases; conversely, as process temperature rises, heat output decreases. C. Jacket. This flame-retardant insulation jacket is a thermoplastic rubber material with excellent water resistance. It also resists certain mildly corrosive chemicals. ߜOverlap OMEGALUX SRL without fear of burnout. ߜSaves energy because selfregulating SRL will throttle itself back as it senses increasing temperatures. ߜCut SRL to any desired length (up to the maximum circuit length). Field splices can be performed easily in minutes. No scrap, no wasted cold sections, no worry! D. Tinned-Copper Braid. Provides additional mechanical protection and a positive ground path. E. Optional Overcoat Over Braid (“-CR” or“-CT”). TPR (“-CR”) or fluoropolymer (“-CT”) jacket over the braid. The TPR coating is for certain aqueous and mainly corrosive solutions. The fluoropolymer coating is used for exposure to most other corrosive materials. Add suffix -CR or -CT to the model number. ߜSurpasses steam tracing by far! Lower installed cost than steam. Less maintenance, expense, and downtime. ߜSelf-regulating effect makes an over-temperature condition virtually impossible. ߜLower installation costs due to easier, faster installation. OMEGALUX termination kits and splice and tee kits expedite installation. APPROVALS Consult page 47 for third-party approval or listing information. MOST POPULAR MODEL HIGHLIGHTED!
