SELF-REGULATING RAPID-TRACE HEATING CABLE/ MEDIUM TEMPERATURE SRM/E Series Starts at ߜ 3, 5, 8, 10, 15, and 20 Watts/ft ߜ 120 and 240V ߜ 150°C (302°F) Maximum Maintenance Temperature APPLICATIONS Standard Construction (refer to lettered callouts in drawing). A. Bus Wires. Twin 14 AWG copper bus wires provide reliable current capability. 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. The 215°C (420°F) maximum exposure temperature rating allows steam cleaning of process equipment with up to 300 psig steam. OMEGALUX® SRM/E heating cables can be used in hazardous as well as certain corrosive areas. He B. Matrix. The electrical resistance of this semiconductive polymer core 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 fluoropolymer FEATURES ߜSteam cleanable. SRM/E can withstand 215°C (420°F), 300 psig steam purging of process piping when not energized. ߜSaves energy. Self-regulating SRM/E uses less energy when less heat is required. ߜCut SRM/E to any desired length (up to maximum circuit length). Field splices can be performed easily in minutes. No scrap, no wasted cold sections, no worry! insulation insulates bus wires and is highly corrosion resistant. D. Metallic Braid (“-C”). Provides a positive ground path and additional mechanical protection. E. Optional Overjacket (“-CT”). Fluoropolymer jacket over-braid provides protection for the braid from most aqueous and chemically corrosive solutions as well as abrasion and impact damage. Add suffix “-CT” to model number. ߜOverlap OMEGALUX SRM/E cable without fear of burnout. ߜSelf-regulating effect makes an over-temperature condition virtually impossible. ߜSurpasses steam tracing by far! Lower installed cost than steam. Less maintenance, expense, and downtime. APPROVALS Consult page 47 for third-party approval or listing information. MOST POPULAR MODELS HIGHLIGHTED! TYPE SRM Metallic Braid (-C) *Minimum length of heating cable is 7.6 m (25') SRM/E cable is also available in 15 W per foot. Contact Sales for price and delivery. See pages 50-53 for heat cable accessories and controls. Ordering Example: SRM/E5-2C-100, 240 Vac heating cable, 5 W per foot, with tinned-copper braid, 30 m (100' ) length, $900. ® or Shop Online at omega.com SM
