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
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.

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
