Constant-Wattage Heating Tape with Adjustable Temperature Control for Pipes and Tubes


Hardwire	Plug In

Turn the dial to control the percentage of time that these heaters cycle on, from 5% to 100%. Commonly used to thaw pipes, prevent valves from freezing, and heat beakers and flasks in labs, they're good for temporary and occasional use where rapid heating is required but precise temperature control is not.

Unlike self-regulating heaters, these provide a consistent heat output wattage along the entire length of the cable, regardless of the environmental temperature. They do not have a temperature sensor, so you should only use them in areas where you can monitor them with a thermometer (sold separately). Do not use behind walls, underground, or in other difficult-to-access areas.

With a rubber coating, these heaters are both moisture and chemical resistant. Install them onto surfaces that are free of dirt, grease, and rough edges using fiberglass tape or heat-transfer putty. Do not use electrical tape, duct tape, metal bands, or wire. To prevent burnout, make sure they're in full contact with the surface and have no overlap. To prevent heat loss, wrap with fiberglass insulation.

Ultra-High Temperature Constant-Wattage Heating Tape for Pipes and Tubes

For demanding applications such as hot-melt transfer pipes, these heaters have a maximum heat output of 1400° F. The wattage and heat output stay consistent along the entire length of the cable, regardless of the temperature of the environment. All require a temperature switch or controller (sold separately) for regulating heat output. To prevent burnout, heaters must not overlap and must be in full contact with the surface being heated.

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.

Plug In—Heaters with a plug require a power controller (sold separately).

High-Temperature Constant-Wattage Heating Tape for Pipes and Tubes


Hardwire	Plug In

With a maximum heat output of 900° F, these heaters are often used for thawing frozen pipes and rapid spot heating. They supply the same wattage along the entire length of the cable, so they remain consistent regardless of the surrounding temperature. To prevent burnout, heaters must not be overlapped and must be in full contact with the surface being heated.

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 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.

Self-Regulating Heating Tape for Pipes and Tubes

Hardwire

Plug In

5-15

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.

Plug In—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.

Constant-Wattage Heating Tape with Temperature Control for Pipes and Tubes

5-15

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.

Plug In

Closeup View of

2.1 mm ID Barrel

Connector

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.

2.1 mm Plug End ID—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.

Cut-to-Length Self-Regulating Heating Tape for Pipes and Tubes

Shown with LED Termination Kit

Shown with

Power-Connection/Termination Kit

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).
