Rectangular Flange Heaters
Rectangular Flange Heaters
Large Diameter Elements provide extra electrical insulation for superior dielectric strength. Element insulation is compacted to insure uniform heat transfer from coil to sheath and all bends are repressed to insure insulation integrity in this critical area. Special sheath materials and alternate flange designs are available for special needs.
Standard Features
Tubular ElementsElements are .475” diameter, and suitable for line voltages up to 600 volts. In addition, element insulation is compacted to insure uniform heat transfer from coil to sheath and all bends are repressed to insure insulation integrity in this critical area.
FlangesFabricated from 3/16” minimum plate. Copper sheathed elements are silver soldered into brass flanges. Steel, Incoloy and stainless steel sheathed elements are welded into flanges of like materials.
Element SpacersMade from 304 stainless steel, spacers maintain a uniform distance between elements, thus preventing hot spots where elements may otherwise touch.
Moisture-Resistant Epoxy SealsEpoxy seals are available if the maximum fluid temperature will not exceed 250° F.
Agency ApprovalCSA labeled units are available with construction modifications.
Special Features
Alternate Flange DesignNon-standard flange sizes and bolt hole locations are available to match existing installations in the field.
Companion FlangesA companion flange, made from the same material as the heater flange, is available with drilled and tapped openings matching the heater mounting holes. The companion flange is welded or brazed to the vessel, and the gasket installed between the heater flange and the companion flange.
