nVent RAYCHEM QTVR self-regulating trace heating cables


Self-regulating trace heating cables for (large) pipe freeze protection and for process temperature maintenance up to 110°C

The RAYCHEM QTVR range of parallel, self-regulating trace heating cables is an ideal solution for freeze protection of large pipes and vessels with high heat loss, and for process temperature maintenance applications up to 110°C (225°F) without steam-cleaning requirement. They all have fluoropolymer outer jackets (-CT) for high chemical resistance against aggressive organics and corrosives.

  • 10QTVR (38 W/m @ 10°C)
  • 15QTVR (51 W/m @ 10°C)
  • 20QTVR (64 W/m @ 10°C)

Key benefits:

  • Simplified design in hazardous area
    • Unconditional T4 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
    • high power output for frost protection applications
    • uniform pipe temperatures and energy savings resulting from the self-regulating technology (Further energy savings can be made with various control and monitoring systems)
