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

.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

current information

Instruction Manual with wiring diagrams are 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.

2" NPT - 5-1/8"

1-1/4" NPT - 4-3/8"
2-1/2" NPT - 5-1/8"

Change "M1" or "M7" catalog designation to "M5"

.
To determine "G" dimension, to the catalog "B" dimension, add:

1" NPT - 5-3/8"
2" NPT - 6-1/4"

1-1/4" NPT - 5-1/2"
2-1/2" NPT - 6-1/4"
