Product details

nVent RAYCHEM  XL-Trace 31XL2 contractor pack comprises a fixed length of 31XL2-ZH heating cable supplied in an easy to use and carry spool box. The spool allows the installer to feed out the required length easily, reducing installation time and effort.  nVent RAYCHEM 31XL-Trace ensures flow maintenance in grease lines and frost protection for larger pipes exposed to sub-zero temperatures. This self-regulating heating cable, combined with pipe insulation is ideal to maintain flow in fatty waste water pipes and ensure frost protection to larger diameter 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
