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.
Versatile tubular elements can be designed for
use in most applications. See guidelines in the
Tubular Heater Overview section.
The metal sheath isolates and protects the
resistor wire from the environment. At the
same time it maximizes heat transfer capability
to the work. Tubular elements can be bent to
put the heat where it works best.
Type 4 Terminals — Integral parts of the element are of high strength to resist bending during tightening of the wiring connections. Type 4 is threaded extension of the cold pin. See terminal detail drawing in the Tubular Heater Overview section.
