| 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. |

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. |

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. |
