Construction
A. Twin 14 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. High Temperature Fluoropolymer Jacket — Flame retardant, electrically insulates the matrix and provides corrosion
resistance.
D. Metallic Braid — Provides additional mechanical protection in any environment and a positive ground path.
E. High Temperature Fluoropolymer Overjacket (optional) — Corrosion resistant, flame retardant overjacket is highly effective in hostile, aqueous and chemically active environments. It also protects against abrasion and impact damage.

Description
Chromalox 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. Constructed of industrial grade 14 AWG buss wire with metal braid and optional overjacketing, SRM/E ensures operating integrity in most hostile industrial environments. The 420°F (215°C) maximum exposure temperature rating allows steam cleaning of process equipment with up to 300 psig steam.

Enhanced Features
• Industrial Grade, 14 gauge buss wire has higher current capacity, allowing longer circuit lengths up to 780 feet.
• Superior matrix to buss wire bonding ensures overall operating integrity and performance.
• High output, 20 W/Ft. heating cable.
• All ratings are available from stock.

Features
• Energy efficient, self-regulating SRM/E uses less energy when less heat is required.
• Easy to install, SRM/E can be cut to any length (up to max. circuit length) in the field.
• Field splices can be performed easily in minutes with no scrap or wasted cold sections.
• With lower installed cost than steam tracing, SRM/E features less maintenance expense and downtime.
• SRM/E can be single overlapped without burnout, which simplifies heat tracing of inline process equipment such as valves, elbows and pumps.
• Because SRM/E is self-regulating, overtemperature conditions are minimized.
• Chromalox termination, splice, tee and end seal kits reduce installation time.

Approvals
Factory Mutual (FM) Approved for ordinary areas. UL Listed, CSA Certified for ordinary areas. FM Approved for hazardous (classified) areas when used with DL 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 filings)
• 3, 5 and 8 Watt Rated T3 Temperature Class
• 8, 10, 15 and 20 Watt Rated T2D Temperature Class CSA Certified for hazardous (classified) areas when used with DL accessories:
• Class I, Div. 2, Groups A, B, C, D
• Class II, Div. 2, Groups F, G
• Rated T31 Temperature Class.
Note 1 Exception — Cable Surface Temperature shall not exceed 190°C in Class II, Div. 2, Group F; 165°C in Class II, Div. 2, Group G.

Note 1 — Thermal output is determined per IEEE 515-1997 Standard for testing, design installation, and maintenance of electrical resistance heat tracing section 4.1.11 Method C.

Note: The SRM/E cable is sold by the foot and therefore a custom order.  Once the order is placed it cannot be cancelled or returned once you receive the cable.  This is because the cable is cut to length here, or at Chromalox, for your order, from your requested length.
