Features

• Elements are designed for maximum: Watt density, temperature, heat transfer, and heater life.
• The Superwatt cartridge heater accelerates the transfer of heat from the resistance wire to the sheath. This is accomplished by relocating the wire so that it is closer to the sheath; and swaging the outside diameter of the heater, thereby compressing the magnesium oxide filler so that it becomes an improved conductor of heat from the wire while maintaining its dielectric properties. (See diagram below). By improving the heat transfer rate, it is possible to manufacture elements of higher densities because the differential between the wire temperature and the sheath temperature has been minimized.
• Long, trouble free service.
• Made in U.S.A

Construction

• Heliarc welded end seal.
• Series 300 stainless steel sheath of precision dimensions and tolerances for intimate, stable, non-oxidizing contact with cavities machined for them.
• Pure magnesium oxide compressed to an optimum density for best heat transfer and electrical insulation at elevated temperatures.
• Element wire situated in close proximity to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric qualities.
• Ceramic cap.
• Fiberglass insulated leads.
