Industrial cartridge heaters are compact solutions for inserting into small industrial furnace openings. They are known by various names, such as bayonet heaters, candle heaters, and radiant heaters, and they are available in diverse designs to meet specific needs.
These heaters are typically used with a protective tube that shields the heating element from the furnace atmosphere. This design enables indirect heating of the furnace through radiation.
