Immersion Heaters
Tubular heating 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.

Tubular Heaters (Formed or Straight)
The most versatile of all electric heating elements, the tubular heater is capable of being formed into virtually and configuration. The basic design consists of a helical coil of nickel-chromium resistance wire precisely centered in a metal sheath. THe coil is surrounded by magnesium oxide powder which is vibration loaded to insure even density throughout the length of the heater. This entire assembly is then reduced to the finished diameter, compacting the MgO and "freezing" the coil in the center of the heater. The range of ratings, sizes, materials and terminations available makes the tubualr heater adaptable to many industrial, commercial and scientific applications.
Sheath Materials:  
Copper Sheath: Water heating, water solutions non-corrosive to copper
Stainless Sheath: Immersion in oils, molten salt baths, alkaline cleaning solutions, tars and asphalt. Also suitable for clamping to metal surfaces and casting into aluminum
Stainless Steel Sheath: Corrosive liquids, food processing equipment
Incoloy Sheath: Air heating, radiant heating, cleaning and degreasing solutions, plating and pickling solutions, corrosive liquids.
Other sheath materials are also available for application considerations. Commonly specified are 316 stainless steel, sopper clad steel for metal casting, Inconel for high temperature applications, and titanium for severely corrosive solution heating.

Ceramic Heaters
Ceramic fiber heaters intergrate a high temperature iron-chrome-aluminum (ICA) heating element wire with ceramic fiber insulation. Numerous stock, standard and/or custom shapes can be provided, acheiving the "heated insulation" concept for your high temperature, non-contact applications. The ceramic fiber insulation isolates the high temperatures inside the heated chamber from the outside. The heaters are low meass, fast heating, with high insulation values and slef-supported heating elements that offer some of the highest temperature heating capabilities within the Hampton family of heater designs.
