When the ambient temperature changes, these heaters automatically adjust the heat output along the length of their cable. Also known as self-regulating heat cable, they don’t require a separate temperature switch or controller. These heaters use their full wattage for more heat when surrounding temperatures are low and reduce their wattage when temperatures are high. Heat output can simultaneously vary at multiple points along a single cable. They’re often used to maintain liquid temperature and viscosity and provide freeze protection in pipe and tube systems. All are CSA certified for pipe freeze protection and are rated for outdoor use. Heaters can overlap without creating hot spots or risking burnout. A protective rubber cover provides corrosion resistance and durability.

Heaters with a plug are also CSA certified for roof and gutter de-icing applications. The plug has an indicator light that shows when the system has power.

Note: Only install these heaters in accessible locations; do not install them behind walls, underground, or in other difficult-to-access areas. Use fiberglass tape or heat-transfer putty to install them directly on surfaces that are free of dirt, grease, and rough edges. Do not use electrical tape, duct tape, metal bands, or wire. To prevent heat loss and protect heaters from moisture and corrosion, wrap them with fiberglass insulation.

Wrap the flexible heating element around small-diameter pipes and tubes or pack it into tight spaces. These heaters maintain a consistent heat output along the entire length of the cable, regardless of the environmental temperature. All require a temperature switch or controller to regulate heat output. They do not produce an electromagnetic field, so they can be used near electronics.

Pair heaters with a 2.1 mm ID barrel connector with an AC adapter (not included) to power them from a standard AC wall outlet.
