nVent RAYCHEM BTV self-regulating trace heating cables


Self-regulating trace heating cables for pipe freeze protection or process temperature maintenance up to 65°C

The RAYCHEM BTV range of self regulating trace heating cables is an ideal solution for freeze protection of pipes and vessels and for process temperature maintenance applications without steam-cleaning requirement.

They maintain process temperatures up to 65°C (150°F) and can withstand intermittent exposure temperatures up to 85°C (185°F).

The polyolefin outer jackets (-CR) are suitable for mild inorganic solutions, whereas the fluoropolymer outer jackets (-CT) offer a high chemical resistance against aggressive organics and corrosives.

  • 3BTV (9 W/m @ 10°C)
  • 5BTV (16 W/m @ 10°C)
  • 8BTV (25 W/m @ 10°C)
  • 10BTV (29 W/m @ 10°C)

Key benefits:

  • Simplified design in hazardous area
    • unconditional T6 temperature classification as specified by European norm EN60079-30-1 (no requirement for sheath temperature calculations / controls)
  • Fast and easy to install
    • multiple overlaps at valves, flanges and on complex piping
    • cut-to-length
    • user-friendly connection kits
    • meter markings on outer jacket
  • Safe, reliable and efficient in operation
    • no risk of overheating even when crossed
    • uniform pipe temperatures and energy savings resulting from the self regulating technology (Further energy savings can be made with various control and monitoring systems)
    • safe trace heating of plastic pipes without additional controls, due to the unconditional T6 rating
