We engineered, design, and supply aluminum immersion heater system for aluminum holding furnace or other furnace type requirements. The radiant heater tube is made from high purity and high density Silicon Nitride. This tube will protect the heater from direct contact to the molten aluminum. This is a very critical application, in which the heating system cannot fail. Failure of heating system will cause the molten aluminum to froze and the Silicon Nitride tube to be broken. Once that happen, furnace cannot continue the operation. That is why it is very important to use only the highest quality Silicon Nitride tube and Immersion heater from KANTHAL. Supported with good engineering design and superior material, KANTHAL aluminum immersion heater system can last up to more than 7 years in operation.
