Product Name: Heatrex Tubular and Finned Tubular Heaters
Product Description
Heatrex Tubular and Finned Tubular Heaters provide a highly efficient,
reliable and low cost means of rapidly supplying heat directly to air, metals
and various types of liquids, depending on the application.
UL and CSA
Many Heatrex Tubular elements are recognized by Underwriters Laboratory (UL) and
certified by the Canadian Standard Association (CSA).
Construction
Nickel-chromium resistance wire is uniformly stretched and imbedded into
magnesium-oxide powder
Resistance wire is accurately centered within a copper, steel or alloy sheath.
Terminals are inserted into the heating coil, and welded.
Threaded terminal pin with hardware
Sheath Diameters: .250/.260, .315, .375, .430, .440, .475, .490, .625
Sheath Materials: Copper, Copper Clad Steel, Stainless Steel, Incoloy, Specials
Available
Benefits and Optional Features:
Element can be formed into almost any shape.
Other wattage/voltage combinations are available.
Various terminal configurations available.
Resistance welded terminals assure a strong mechanical and electrical joint.
Coil is sealed into position which eliminates \"hot spots\" and produces a long
life element with efficient heat transfer and positive electrical insulation.
Available in a wide range of wattage/voltages, watt densities, overall lengths,
heated lengths, diameters and sheath materials.
Heatrex Tubular and Finned Tubular Heaters may be clamped against or set into a
surface; immersed into liquids, molten salts or soft metal; used to heat air in
ducts or ovens; or cast in aluminum, lead, concrete or cast iron.
Finned Tubular Heaters
Heatrex Finned Tubular Heaters are used for natural or forced convection space
heating and industrial process air heating. Sheath temperatures are suitable for
drying, heat treating, annealing, curing in ovens or dryers and air heating in
ducts.

.430 sheath diameter with outside fin diameter of 1-5/16\" in straight lengths or
factory formed \"U\" bend or \"W\" bend
Choice of terminals (threaded stud and locknut, ceramic-to-metal seal, threaded
terminal and mounting bushing, ceramic-to-metal seal and mounting bushings)
11 watts per square inch of surface
75 watts per square inch of sheath
240v or 480v
Benefits and Optional Features:
Monel and other sheath and fin materials available
Special voltage/wattages available
Custom bend formations
Special terminations available
l/4\" and 5/16\" fins available
Other sheath diameters available: .250, .260, .315, .375, .490
Copper brazed fins help to provide corrosion resistance and superior
fin-to-sheath adhesion
Cooler internal element temperatures
