nVent RAYCHEM GM constant wattage trace heating cables

Overview

Constant Wattage heating cables for roof & gutter snow melting and de-icing

The IceStop GM – CW systems are suitable for standard roof material like slate, shingle, metal and roofing tiles for standard material of gutters and drainpipes.

The GM-2(4) CW heating cables are available in kits of varying pre-terminated lengths with different ohm resistances.

The kits include a cold lead connection and end seal. The heating cable can be ordered in two different voltage ranges, 230 V or 400 V AC. Key benefits:

  • Easy installation
    • available in Pre-terminated Kit
    • cold lead with 5 m length
    • wide range of fixing material for fast and easy installation
  • Safe:
    • Is designed according to IEC EN 62395
    • Provides maximum abrasion, chemical, and mechanical resistance
    • Better temperature control
  • The right cable for each situation:
    • GM-2CW for 230 VAC
    • GM-4CW for 400 VAC and longer heating circuits

Further energy savings can be achieved through the EMDR-10 control systems.
