  • Heat transfer oils - Molding dies and platens, closed loop heat transfer systems for heat sensitive materials
  • Fuel oil heating - Pre-heating for delivery to burners, pre-heating to pumping viscosity
  • Water - Dishwashing and rinsing, hot water storage tanks, process water, jacketed kettles.
  • Air, gasses, steam- Process air, boosting temperatures of gasses, steam superheating


Tubular heaters or Mighty-Blade elements are brazed or welded into a standard pipe flanged. 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 flanged welded to the vessel wall.

  • 150 Ib. ASA carbon steel flanges 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

Ogden Flanged Immersion Heaters

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.


Ogden Pipe Plug Immersion Heaters

Tubular heaters or Mighty-Blade elements are brazed or welded in a brass, steel or stainless steel pipe plug. Ratings from 350 watts to 38kw and numerous variations and options are available. Pipe plug immersion heaters are generally used in small to medium size containers at pressures up to 3000 psi and are screwed directly through a threaded opening in the tank wall.  

  • 1", 1-1/4", 2" and 2-1/2" NPT pipe plug in brass, steel or stainless steel
  • 0.312" diameter tubular element(s) on 1" and 1-1/4"; .475" diameter elements on 2" and 2-1/2" or .275" x 1" Mighty-Blade element(s)
  • Copper, steel, stainless steel, or Incoloy sheath material. Mighty-Blade sheath material is Incoloy
  • High, medium and low watt densities for various processes
  • General purpose or explosion and moisture resistant terminal enclosures
  • Tubular element ends are repressed after forming to extend element life
  • Element supports on larger size units maintain element spacing
  • Single and double pole thermostats in several temperature ranges
  • Many items are available from stock. Request a Stock List for most current information
  • Instruction Manual with wiring diagrams are included with each unit


Used in tanks where through-the-wall heaters cannot be installed, portability is required, or where heaters must be removed for cleaning without emptying the tank. Suitable for freeze protection, for heating viscous materials to improve flow, or most open tank applications with proper sheath and watt density selection.
