Superior Power Output
Bundle rod elements, with a higher power output, leads to major saving in cost and maintenance. Also when combined with radiant tubes, they give highest power rating (up to 100 kW) as compared to any other heater. 

Easy installation
Due to its ruggedness and versatility, bundle rod elements are easy to install and replace. Compatibility with radiant tubes allows installation to be either horizontal or vertical depending on the application. Easy repair and high temperature performance gives it an edge over others.

Custom designed for the voltage and wattage required, bundle rod heaters are used in heat treat furnaces and die casting machines to molten salt baths and incinerators. With radiant tubes they can be used in high velocity convection furnaces and sealed quenched furnaces. They are also useful in converting gas-fired furnaces to electric heating.

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. Is longer than the terminal rods.
  • Ceramic Disc : Used to encompass all the heating elements to form a bundle. Made of Alumina. Usually flower shape.
