  • For Use on Metal and Plastic Pipes
  • Factory Mutual (FM) Approved, UL Listed, and CSA certified for ordinary areas.
  • ATEX, IECEx, FM, and CSA Approved for hazardous (classified) areas when used with U Series, HL, DL, and EL accessories.


  • Energy efficient, self-regulating SRL uses less energy when less heat is required.
  • Easy to install, SRL 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.
  • SRL features lower installed cost than steam tracing, less maintenance expense and less downtime.
  • SRL can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps.
  • Because SRL is self-regulating, over-temperature conditions are minimized.
  • Chromalox termination, splice, tee and end seal kits reduce installation time.
