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.
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.
304 stainless steel heating elements are more corrosion resistant than copper heating elements.
316 stainless steel heating elements are more corrosion resistant than 304 stainless steel and copper heating elements.
Incoloy heating elements have the best corrosion resistance.
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.

Compact Screw-Plug Immersion Heaters for Water


Efficiently heat liquid in small containers. These immersion heaters install into threaded container openings or pipe couplings. All require a temperature switch or controller (sold separately) to regulate heat output. The heating element is 316 stainless steel for excellent corrosion resistance.
Note: Fully immerse the heating element in liquid to prevent heater failure.

Sanitary Screw-Plug Immersion Heaters for Water



Heat water through direct contact in sanitary areas such as food, cosmetic, and pharmaceutical plants. Made of 316 stainless steel, these immersion heaters won’t corrode from harsh cleaners and sanitizers. To minimize bacteria growth and make them easier to clean, the heating element has an electropolished finish that’s free of crevices. Rated NEMA 4, their housing is protected against dirt and washdowns.
These heaters have screw plugs for mounting to threaded container openings or pipe couplings.
Heaters with an adjustable thermostat automatically turn on when the water drops below a set temperature and turn off once it reaches that temperature. Heaters without an adjustable thermostat require a temperature switch or controller (not included) to control heat output.
Note: Fully immerse the heating element in liquid to prevent heater failure.

Screw-Plug Immersion Heaters for Oil and Coolant
To heat oil and coolant without creating hot spots and damaging the heating element, these heaters have a lower watt density than heaters for water or chemicals. They install into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.
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.
Incoloy heating elements are more corrosion resistant than steel heating elements.
Note: Fully immerse the heating element in liquid to prevent heater failure. These heaters install through threaded container openings or pipe couplings.

Compact Screw-Plug Immersion Heaters for Chemical Solutions


Use these heaters to efficiently heat liquid in small containers. They install into threaded container openings or pipe couplings. All are designed to heat chemical solutions at much higher watt densities than other immersion heaters without damaging the heating element. Heaters require a temperature switch or controller (sold separately) to regulate heat output. The heating element is Incoloy for excellent resistance to harsh chemicals.
Note: Fully immerse the heating element in liquid to prevent heater failure.
