Screw Plug Immersion

Screw plug immersion heaters consist of tubular elements in a threaded hex plug. Some screw plug immersion heaters are provided with a thermowell for the temperature control sensor and a variety of electrical enclosures for electrical connections. Screw plug immersion heaters screw directly through threaded openings in tank walls to heat liquids, viscous fluids, forced air, and gases by direct contact.
