Flanged Immersion Heaters
Tubular heaters or Mighty-Blade elements are brazed or welded into a standard pipe flange. 3″, 4″, 5″, 6″, 8″, 10″, 12″ and 14″ are standard sizes. Flanged immersion heaters are used in large capacity vessels, in high pressure applications and are installed by bolting the unit to a matching flange welded to the vessel wall.

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