Also known as cartridge heaters, insertion heaters install into drilled and reamed holes in metal parts for quick heating through direct contact.

A bonded-graphite coating acts as a dry lubricant to ease insertion and removal for cleaning.

These heaters require a separate temperature switch or controller to regulate heat output.

For more durability than other adhesive-mount heaters, a thick layer of fiberglass-reinforced silicone rubber encases the heating element.

These heaters are rated for environments where hazardous material is present.

Nonstandard-size containers are no problem—use the hook-and-loop closure to adjust these heaters to fit a range of diameters.

Also known as heat blankets, these heaters completely surround containers for fast heating and increased heat retention in unheated and drafty areas.

Attach to flat metal surfaces.

Install these heaters into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.

Heat water through direct contact in sanitary areas such as food, cosmetic, and pharmaceutical plants.

Also known as circulation heaters, these install directly into pipelines.

Sized to fit drums, these heaters have a bracket to hook on the side of drums and in bung openings.

A replaceable fuse cuts off power if the heating element reaches 190° F to prevent burnout and premature failure. Bolt the flange to the top of containers.

Use these heaters to efficiently heat liquid in small containers.

Form these heaters into any shape and install them through container walls with the attached bulkhead fittings.

These heaters install through threaded container openings or pipe couplings.

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.
