Bundle Rod Heater

Bundle Rod Heaters are premium industrial heating elements specifically engineered for high-temperature furnaces and heavy-duty thermal processing applications. These advanced rod type heating elements feature a sophisticated construction comprising multiple terminal rods, a central support rod, and precision-engineered ceramic discs that form an efficient heating bundle capable of withstanding extreme operational demands.

Construction

Terminal Rod: Carries the power supply wiring. Usually made of FeCrAl, SS310 or INCOLOY. Number of rods depend upon the supply connection.
Center Rod: Used to provide central support to the heater. Usually made of FeCrAl, SS310 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.
Top Plate: Holds and supports terminal rods and central rod. Provides structural stability and secure mounting of the heater assembly.
