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
