Design and Construction

Marathon makes a Bundle rod heater that consists of a circular ceramic disc that holds the heating elements. In combination with the radiant tubes which deliver high power, avoid refractory corrosion and avoid the gas impurity in process materials. These are designed for long life and maintenance-free operation. The element can be provided in Ferritic alloys up to 1250° C and NiCr alloy up to 1100°C materials.

Components of Bundle Rod Heaters

Terminal Rod:

Carries the power supply wiring. Usually made of SS 310 or INCOLOY. The number of rods depends 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.

The design and construction of these heaters are meticulously engineered to ensure optimal performance and durability.
