Immersion Heaters
Screwplug
Screwplug Immersion heaters include one, two or three hair-pin bent tubular element(s) joined to a threaded hex plug. Screwed into tank walls, this UL Listed/CSA Certified direct contact heat source heats liquids, viscous fluids, forced air and gases with maximum energy efficiency. In addition, elements can be bent in many configurations to suit a variety of applications. Most screwplug heaters come with a thermowell (for temperature control sensor) and a completely wired terminal box for electrical connection. Certain models available with a patented 360° rotatable screwplug housing to facilitate easy conduit connections. Select from a wide variety of sheath materials. Various element lengths, plug sizes and ratings from 0.5 kW and up, for 120 to 600 volts.
Flanged
Flanged Immersion heater construction is similar to the screwplug immersion heater with elements joined to a flange (36" max. dia.) that mates with a matching companion flange in a vessel wall. Ideal for generating steam or heating gases and liquids for use in pressure vessels and tanks. Factory designed with a wide selection of ANSI and custom sized flanges for industrial and OEM applications. Element lengths to 240" long and rated up to 500 kW with watt densities to suit many applications. Most units are UL Listed and CSA Certified.
