Pipe Plug Immersion Heaters - Screw Plug Immersion Heaters
 Pipe plug immersion heaters are generally used in small to medium size containers at pressures up to 3000 psi and are screwed directly through a threaded opening in the tank wall. Tubular heating elements are brazed or welded in a brass, steel or stainless steel pipe plug. Ratings from 350 watts to 38kw and numerous variations and options are available.

Pipe Plug Immersion Heaters Applications:
-
Copper Sheath: Clean Water, freeze protection, hot water storage, boiler and water heaters, cooling towers, heating of solutions not corrosive to copper
-
Stainless Steel Sheath: Process water, soap and detergent solutions, soluble cutting oils, demineralized or deionized water (passivation recommended)
-
Incoloy Sheath: Solution water, corrosive solutions, steam super heating, air or gas
-
Steel Sheath: Asphalt, wax, paraffin, tar, fluid heat transfer medium, petroleum, degreasing and solvent oils, machine oil, fuel oils, alcohol
Be certain that the sheath material and watt density selected are compatible with the material being heated and the operating temperature.
