Screw Plug Immersion Heaters

Screw Plug Immersion Heaters, Screw, Plug, Immersion, Heaters, screwplug, heatingScrew plug immersion heaters are ideal for are ideal for direct immersion heating of liquids, including all types of oils and heat transfer solutions where space and connections are a problem. Screw plug immersion heaters can have from 1 to 3 elements, or blades, either welded or brazed into the screw plug.

 

Screw plug immersion heaters are installed in medium to small size containers at pressures up to 3000 PSI. Watt densities from 90 Watts/sq. inch, Explosion Proof (NEMA 7), Corrosion Resistant (NEMA 4X), and General Purpose Terminal housings are available.

 

A number of sheath materials like Titanium, Incoloy, Stainless Steel, Steel, and Copper can be used as required for specific applications. To guarantee sheath material and watt density compatibility with material or process being heated consult HCS.
