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.
- Immersion (Corrosive Liquids, Fry Kettles, etc.)
- Low Temperature Air Heating
Flat-Pressed after triangulation to increase
contact surface, improve heat conductivity.
Series Wiring — Two or more elements of
equal wattage may be connected in series on
line voltages up to 480 volts. For application
details see Tubular Heater Overview section.
Type 3 and 4 Terminals — Type 3 (3/8" dia.)
are Heliarc-welded to cold pin. Type 4 (7/16"
dia.) are threaded end of cold pin. See terminal
detail drawings in the Tubular Heaters Overview
Bending — Generally not recommended for
flat-pressed, triangulated elements.
