Hazardous Location Adhesive-Mount Heaters for Pails, Drums, and Tanks

These heaters are rated for environments where hazardous material is present. Also known as heat sheets, they are flexible and permanently adhere to container surfaces to warm contents without direct contact. All have a watt density of 2.5 W/sq. in. for gentle warming. Heaters require a temperature switch or controller to regulate heat output and should be installed with Dow Corning 736 silicone sealant (both not included).
Note: Do not cut, crease, or overlap these heaters—this will damage the heating element. Use a roller during installation to remove air pockets and ensure direct surface contact. Once heaters have been applied to a surface, they cannot be removed and reused.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Constant-Wattage Heaters for Pipes and Tubes



Since these heaters continually supply the same wattage regardless of the surrounding temperature, they’re less prone to power surges than self-regulating heaters. 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. It also includes adhesive, an end cap, and a power-connection cover.
Termination kit (sold separately) includes adhesive, an end cap, and a power-connection cover.
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.
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.

Self-Regulating Heaters for Pipes and Tubes



Also known as self-regulating heat cable, these heaters automatically adjust heat output in response to surface and surrounding temperatures without the need for a separate temperature-control device. 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 (sold separately) include a junction box and a three-point DIN-mount terminal. They also include adhesive, an end cap, and a power-connection cover.
Termination kits (sold separately) include adhesive, an end cap, and a power-connection cover.
LED termination kits (sold separately) 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.
Splice kits (sold separately) include adhesive, splice-connection covers, and wire-splicing connectors.
T-splice kits (sold separately) 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. To prevent heat loss and protect heaters from moisture and corrosion, wrap them with fiberglass insulation.
