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.

150 Ib. ASA carbon steel flange from 3" to 14" sizes .475" diameter copper, steel, stainless steel, Incoloy tubular elements, or .275" x 1" Incoloy Mighty-Blade elements 90, 45, 30, 22, 15, 13, 8 and 6.5 watts/square inch elements for various processes General purpose, moisture or explosion resistant terminal enclosures Thermowell for 3/8" diameter thermostat bulb Tubular element bends are repressed after forming to extend element life Instruction Manual with wiring instructions included with each unit

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.

Options

Special rating or immersion length 316 stainless steel or other sheath material Passivation Electropolishing 300 lb. or greater ASA flange Other material for flange Built-in thermostat Thermocouple attached to sheath for high-limit protection Baffles to increase material flow velocity Larger flange sizes Stand-off terminal enclosure to isolate terminals and wiring from flange in high temperature process .625" diameter elements to lower watt density or increase wattage ASME Certification

Flange Size	Standard No. of Tubular Elements	Can Be Increased To:	Number of Mighty-Blade Elements
3	3	6	--
4	6	--	6
5	6	12	--
6	12	15	15
