Working Principle
The Ducted Explosion-Proof Air Heater operates using tubular electric heating elements sealed within certified explosion-proof housings. High-temperature resistance wires are enclosed in metal tubes, with crystalline magnesium oxide powder providing electrical insulation and efficient heat transfer.
Air passing through the duct absorbs heat from the elements while the explosion-proof design prevents sparks or excessive surface temperatures, ensuring safe operation in flammable atmospheres. This makes it ideal for classified areas requiring controlled, heated air supply without ignition risks.
