Tubular heating elements perform exceptional industrial heat transfer by conduction, convection, or radiation to heat liquids, air, gases, and surfaces. In most commercial heater assemblies, tubular element design configurations vary: round, triangular, flat press, and formed. Bends are made to customer requirements: custom built from 0.200" to 0.475" diameters, a multitude of sheath materials with sheath temperature capabilities up to 1600°F, and watt densities to fit many applications up to 600 volts. Available with over 20 optional terminations and many stocked accessories.

Type 8 Terminals- Standard with threaded clip to facilitate wiring.

Type 3 Terminals- Heliarc-welded to the cold pin. See terminal detail drawing in the Tubular Heater Overview Section.

Retaining Rings- Locate elements in radiant heater assemblies.

Work Temperatures- See Tubular Heaters Overview Section.

Bending- Lengthwise only. See bending requirements Tubular Heater Overview Section.
