CLT Series Heating Cables

Commercial-Grade Heating Cable for Water Supply and Drain Pipes, Roofs and Gutters, or Maintaining the Temperature and Flow of Piped Liquids. Self Regulating, Cut-to-Length.

CLT Series heating cables provide a industrial and commercial-grade solution for preventing frozen pipes or ice damming of roofs and gutters. These self-regulating, cut-to-length cables are normally installed in commercial and light industrial applications, to maintain pipe temperature and prevent freezing in ambient temperatures down to -40°C/-40°F. They can also be used to maintain liquids in pipes at a constant temperature or maintain constant viscosity and flow. For roof and gutter heating, CLT Series cables can be installed on a wide variety of roofing materials, including temperature-sensitive roof coatings.

CLT Series cables can be installed in dry or wet environments and are available in power densities of 3, 5 and 8 watts per foot, at 10°C/50°F for both 120 Vac and 240 Vac when installed on insulated metallic pipes and vessels. 240 Vac cables can also be used in 208 Vac or 277 Vac applications. A wide range of accessories is available to simplify installation and adapt to individual application requirements. Cables are UL Listed and CSA Certified for use in non-hazardous locations and can be used on branch sprinkler systems.
