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.

• Min. Bend Radius 1-1/8"
• For Use on Metal and Plastic Pipes
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 op- erating integrity in Div. 2 hazardous environ- ments as well as certain corrosive industrial environments. SRL heating cable
has a maximum maintenance temperature rating of 150°F (65°C).
WARNING — A ground fault protection device is required by NEC to minimize the danger of fire if the heating cable is damaged or improp- erly installed. A minimum trip level of 30mA is recommended to minimize nuisance tripping.
• Field splices can be performed easily in min- utes with no scrap or wasted cold sections.
• SRL features lower installed cost than steam tracing, less maintenance expense and less downtime.
Approvals
ATEX and IECEX Exe IIGb, Factory Mutual (FM) Approved for ordinary areas. UL Listed, CSA Certified for ordinary areas. UL listed for freeze protection of fire protection system piping. FM Approved for hazardous (classified) areas when used with U Series, DL and EL accessories:
• Class I, Div. 2, Groups B, C, D (gases, vapors)
• Class II, Div. 2, Groups F, G (combustible dust)
• Class III, Div. 2
(easily ignitable fibers and fillings)
• 3 Watt Rated T6 Temperature Class
• 5 and 8 Watt Rated T5 Temperature Class • 10 Watt Rated T4A Temperature Class.
CSA Certified for hazardous areas when used with DL, EL or U Series accessories:
• Class I, Div. 2, Groups A, B, C, D • Class II, Div. 2, Groups F, G.
• ATEX and IECEX Exe IIGb
• IIG Exe II
Cut to Length in Field
Can be Single Overlapped
• SRL can be overlapped without burnout, which simplifies heat tracing of in-line pro- cess equipment such as valves, elbows and pumps.
• Because SRL is self-regulating, over-temper- ature conditions are minimized.
• Chromalox termination, splice, tee and end seal kits reduce installation time.
Construction
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.
