Product details

RAYCHEM 31XL2 heating cable supplied cut to length. RAYCHEM XL-Trace range ensures frost protection for pipes exposed to sub-zero temperatures. This self-regulating heating cable range, combined with pipe insulation prevent water pipes, fire mains and sprinklers from freezing. Developed for use within commercial and residential buildings. XL-Trace cables are designed for use with a RayClic fast connection device

XL-Trace: Features & Benefits

  • Unparalleled safety: low smoke zero halogen: up to 90% less smoke emissions, improved self-extinguishing properties
  • Simple to design: long circuit lengths to 114 m, for fewer power connections and faster installation
  • Easy to install: highly flexible cable, cut to length, fast RayClic cold connection system
  • Energy efficient and safe: self-regulating cable, advanced energy saving controls, major savings when used with proportional ambient sensing controller (PASC), no cable overheating possible
  • Reliable long life: UV resistant, colorfast, maintenance free, 10 year product warranty available
