Straight Tubular Heaters and Formed Tubular Heaters

• Straight Tubular Heaters and Formed Tubular Heaters
  Tubular heaters is capable of being formed into virtually any configuration. The basic design consists of a helical coil of nickel-chromium resistance wire precisely centered in a metal sheath. This 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 tubular heater adaptable to many industrial, commercial and scientific applications.
   
  The Hotwatt Tubular Heater has built-in resistance to shock, vibration, corrosion and temperature extremes.   
  The heater is swaged, reducing the diameter of the metal sheath and compacting the insulation. This insures rapid heat transfer and holds the coil in position for forming. Many formations are available.
  
  Steel, stainless steel, copper, or Incoloy sheathed elements.
  Element wire situated in proximity to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities.
  Pure magnesium oxide compressed to an optimum density for best heat transfer and electrical insulation at elevated temperatures.
  Weld connection.
  Cold pin.
  Insulator.
  Standard post terminal.
