Explosion-proof electric heaters are generally used in places where there is a risk of explosion. Due to the presence of flammable and explosive oils, gases, dust, etc. in the surrounding environment, contact with electric sparks can cause an explosion. Therefore, heating in such places requires the selection of explosion-proof electric heaters
The primary explosion-proof method of explosion-proof electric heaters is to have an explosion-proof device in the junction box of the heater to eliminate the risk of ignition by electric sparks. For different heating scenarios, the explosion-proof level requirements of the heater also vary, depending on the specific situation. Common application scenarios of explosion-proof electric heaters include:
1. Heating and temperature raising of chemical materials in the chemical industry, drying of certain powders under specific pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air), water gas, etc., which require temperature raising.
4. Due to the adoption of advanced explosion-proof design, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion protection.
