Screw-Plug Immersion Heaters, Tubular Bushing Heaters

Screw-Plug Immersion Heater Screw-Plug Heater Enclosures Common Nema Enclosure Types Screw-Plug Immersion Heater (without Thermostat) Screw-Plug Immersion Heater (with Thermostat)		Screw-Plug Immersion Heaters - Description Screw-Plug Immersion Heaters consist of tubular heating elements which are brazed or welded into a threaded brass, steel or stainless steel screw plug. Screw-plug heaters or bushing heaters as they are sometimes referred to, can then be inserted into a threaded opening in a tank wall or through a mating full of half coupling. Screw-Plug Immersion Heaters are used to heat fluids such as water, oil, chemical solutions, mild acids, electroplating and salt solutions. Listed below are some of the recommended watt densities to heat various fluids and gases. 90, 60 & 45 Watts/Square Inch For industrial water heating of many acqueous solutions which accept heat easily. 23 Watts/Square Inch Industrial process heating of many light oils and cooling fluids for some corrosive solutions along with air and gas heating. 15 & 12 Watts/Square Inch For industrial heating of medium viscosity oils, high temperature air and gas heating. 8 Watts/Square Inch For heating of #5 and #6 fuel oil, viscous materials, raw crude oil and residual oils. 6 Watts/Square Inch For heating #6 fuel oil, very viscous materials and fluids that do not accept heat readily.
