Chromalox SLL Series Long Line Heat Trace


  • Exceeds limitations of parallel resistance cables.
  • Field splices can be performed easily in minutes with no scrap or wasted cold sections.
  • With lower installed cost than steam tracing, SLL features less maintenance expense and downtime.
  • Chromalox termination, splice, tee, and end seal kits reduce installation time.

Chromalox SLL Series Long Line cable provides safe, reliable heat tracing for process temperature maintenance and freeze protection of pipes, valves, tanks, and similar applications. Constructed of industrial grade 16, 14, 12 or 10 AWG buss wire with metal braid and fluropolymer overjacketing, SLL ensures operating integrity in most hostile industrial environments. The 450°F (232°C) maximum exposure temperature rating allows steam cleaning of process equipment with up to 300 psig steam.

A.  Twin 16, 14, 12, 10 AWG Copper Buss Wires — Provide reliable electrical current capability.

B. High-Temperature Fluropolymer Core Matrix — Flame retardant, electrically insulates the matrix and provides corrosion resistance.

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 — Corrosion-resistant, flame retardant overjacket is highly effective in hostile, aqueous, and chemically active environments. It also protects against abrasion and impact damage.
