Selecting an Insertion Heater

Insertion Heaters for Plates, Molds, and Dies

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

Insertion Heaters with Internal Temperature
Sensor for Plates, Molds, and Dies

The built-in thermocouple eliminates the need for an external temperature sensor.

Easy-Maintenance Insertion
Heaters for Plates, Molds, and Dies

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

Compact Screw-Plug Immersion Heaters for Water

Efficiently heat liquid in small containers.

Screw-Plug Immersion Heaters for Water

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

Sanitary Screw-Plug Immersion Heaters for Water

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

Hanging Immersion Heaters for Water

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

Flange-Mount Immersion Heaters for Water

Bolt the flange to a matching flange welded on a container wall.

Drop-In Immersion Heaters for Water

Often used for temporary heating in sinks and pails, these heaters have a circular base that sits at the bottom of containers. Remove them from the container after heating its contents.
