ECONOMICAL, SELF-REGULATING FREEZE PROTECTION HEATING CABLE SRF SERIES 25' Length Basic Unit A. Buss wires. Twin 16 AWG copper buss wires provide good current capability. ߜ Commercial Construction ߜ Cooling Towers ߜ Chilled Water and Plumbing Pipes ߜ Sump Discharge Pipes ߜ Wet Sprinkler Systems ߜ Exposed P-Traps INDUSTRIAL APPLICATIONS ߜ Water Treatment Facilities ߜ Vessel Freeze Protection ߜ Safety Shower Lines ߜ Listed for Ordinary Areas ߜ Factory Mutual Approved for Ordinary Areas ߜ CSA Certified for Ordinary Areas Recommended Reference Book: Maintenance Engineering Handbook, MS-0345, $150 See Section Y For Additional Books D. Tinned-Copper Braid. The braid covering the jacket provides additional mechanical protection and a positive ground path. 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. E. Optional High Temp TPR Overjacket. The TPR overcoat protects the braid and provides resistance to certain inorganic chemical solutions. Add suffix -CR to the model number. C. Jacket. This flame-retardant insulation jacket is a thermoplastic rubber material with excellent He water resistance. It also resists certain mildly corrosive chemicals. Standard Construction OMEGALUX® SRF cable is ideal for keeping metal and plastic pipes warm in commercial construction, institutional buildings, and some industrial freeze-protection applications. SRF cable is constructed of a self-regulating polymer core that varies its output along its entire length, saving ߜ Self-Regulating, EnergyEfficient Freeze Protection ߜ Cost-Effective for Contractor/Construction Applications ߜ Industrial Grade, 16 AWG Wire Buss ߜ Longer Circuit Paths, Up to 128 m (420') at 240V ߜ 3, 5, and 8 W ߜ 120, 208 to 277V ߜ UL, FM, CSA Approvals energy and eliminating hot spots along the pipe. The parallel construction makes it easier to install than zone or series types of cable since it can be cut to length at any point on the pipe. It can be overlapped without overheating the cable.
