Rapidly heat water in small containers to prevent freezing or generate steam. Compact in size, these heaters fit in openings that are 1 ¼ NPT or smaller. With a high-watt density, they heat liquids up quickly. Inside the sheath is a heating element made of Incoloy or 316 stainless steel that won’t corrode when exposed to water and moisture.

Both ends of the fitting are threaded, so one side fits into your tank and the other can be threaded into conduit to protect the wiring. For the most even heat distribution, choose the largest length of heater that will fit in your container. All require a temperature switch or controller (sold separately) to regulate the heat output and power the heater.

Note: Fully immerse the heating element in liquid to prevent heater failure.

Install these heaters into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact. The heating element is Incoloy for excellent resistance to harsh chemicals.

Heaters without temperature control require a temperature switch or controller (sold separately) to regulate heat output.

Heaters with an adjustable thermostat automatically turn on when the temperature drops below the set temperature and off when it rises above the set temperature. Adjust the set temperature with the dial.

Note: Fully immerse the heating element in liquid to prevent heater failure.
