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.
