A nonadjustable thermostat turns these heaters on when the temperature drops below 38° F and turns them off when the temperature reaches 45° F. Often used to maintain liquid temperature and viscosity and provide freeze protection in pipe and tube systems, they supply the same wattage regardless of the surrounding temperature and are less prone to power surges than self-regulating heaters. To prevent burnout, they should be installed straight along pipes and tubes; they must not be overlapped or spiraled and must be in full contact with the surface being heated. All are rated for outdoor use. The plastic cable cover provides corrosion resistance and durability. Heaters have a plug with 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.

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.

With a cable that supplies the same wattage along the entire length, these heaters remain consistent regardless of the surrounding temperature. All require a temperature switch or controller (sold separately) to regulate heat output. They’re often used to maintain liquid temperature and viscosity and provide freeze protection in pipe and tube systems. To prevent burnout, heaters must not be overlapped and must be in full contact with the surface being heated. All have a plastic cable cover for corrosion resistance and durability. They are FM approved for hazardous locations. A power-connection/termination kit (sold separately) is required.

Power-connection/termination kit (sold separately) includes a junction box and a three-point DIN-mount terminal block to attach to your power source. It also includes adhesive, an end cap, and a power-connection cover to seal off the other end of your cable.

Termination kit (sold separately) includes adhesive, an end cap, and a power-connection cover to seal off the non-powered end of your cable.

LED termination kit (sold separately) has a high-visibility green LED to indicate when the heater is on. It also includes adhesive, an end cap, and a power-connection cover to seal off the non-powered end of your cable.

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.

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.

Also known as self-regulating heat cable, these heaters automatically adjust heat output at different points along their length to account for differences in environmental temperature. They output their full wattage where temperature is low and heat is needed. Where it’s warmer, they output reduced wattage. They’re often used to maintain liquid temperature and viscosity and provide freeze protection in pipe and tube systems. Heaters can be overlapped without creating hot spots or risking burnout. All require a power connection/termination kit (sold separately).

Heaters with a plastic cable cover are rated for use in hazardous locations. They are also more corrosion resistant and durable than heaters without a cable cover.

Power-connection/termination kits include a junction box and a three-point DIN-mount terminal block for attaching your power source. They also include adhesive, an end cap, and a power-connection cover to seal off the other end of your cable.

Termination kits include adhesive, an end cap, and a power-connection cover to seal off the non-powered end of your cable.

LED termination kits have a high-visibility green LED to indicate when the heater is on. They also include adhesive, an end cap, and a power-connection cover to seal off the non-powered end of your cable.

Splice kits let you connect two heating cables. They include adhesive, splice-connection covers, and wire-splicing connectors.

T-splice kits let you create a tee connection between heating cables. They include adhesive, splice-connection covers, and wire-splicing connectors.

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.
