Explosion-proof Principle
Explosion-proof heaters are generally used in hazardous situations where explosions may occur. Due to the presence of flammable and explosive oils, gases, dust, etc., in the surrounding environment, contact with electrical sparks can cause explosions. Therefore, explosion-proof heaters are required for heating in such situations. The main explosion-proof measure of explosion-proof heaters is that there is an explosion-proof device in the junction box of the heater to eliminate the risk of ignition by electrical sparks. For different heating situations, the explosion-proof level requirements of the heater vary, depending on the specific conditions.
Application Range
Typical applications of explosion-proof electric heaters mainly include:
1. Heating of chemical materials in the chemical industry, drying of some powders under certain pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
