Explosion Proof Heater
Explosion-proof heater is generally used in the presence of a possible explosion of dangerous occasions, due to the existence of flammable and explosive oil, gas, dust and so on in the surrounding environment, once exposed to sparks will cause explosion, so in this occasion heating will need to use explosion-proof heater. The main explosion-proof measure of the explosion-proof heater is that there is a explosion-proof device in the junction box of the heater to eliminate the hidden danger of electric spark detonation. For different heating occasions, the explosion-proof grade requirements of the heater are also different, depending on the specific situation.

The main application fields of explosion-proof electric heater are:
1, chemical industry of chemical materials heating, some powder drying under a certain pressure, chemical process and spray drying.
2, hydrocarbon heating, including petroleum crude oil, heavy oil, fuel oil, heat conduction oil, lubricating oil, stone wax, etc
3, process water, superheated steam, molten salt, nitrogen (air) gas, water gas and other fluid heating heating.
4, due to the use of advanced explosion-proof structure, the equipment can be widely used in chemical industry, military industry, oil, natural gas, offshore platforms, ships, mining areas and other explosion-proof sites.
