BUNDLE ROD HEATER


Our firm is counted amongst the acclaimed manufacture and trader of an exclusive collection of Bundle Heating Element. Our rendered heaters are broadly used in all sorts of heat treatment furnaces including horizontally and vertically up to 1050° c. In addition, these also find application in sealed quench furnaces. The offered elements with hairpin bends are well supported with the high level of temperature. These bundle rods are available at the competitive prices.


COMPONENTS OF BUNDLE ROD HEATERS


  • • Terminal Rod: Carries the power supply wiring. Usually made of SS 310 or INCOLOY. Number of rods depend upon the supply connection.
  • • Center Rod: Used to provide central support to the heater. Usually made of SS 310 or INCOLOY. It is longer than the terminal rods.
  • • Ceramic Disc: Used to encompass all the heating elements to form a bundle. Made of Alumina. Usually of flower shape.
  • • Fiber Disc: Used to hold the terminal rods and central rod together. Inserted in the cold zone of the heater. Made of ceramic fiber.
