In industries such as petrochemicals, pharmaceuticals, military, and grain storage, humid air not only affects production efficiency and product quality, 

but also may cause serious safety accidents due to electrical short circuits, metal corrosion, or dust explosions. Ordinary dehumidifiers cannot be used 

in these high-risk environments, while explosion-proof dehumidifiers, with their special design and safety certification, have become the ideal choice 

for these places. 

What is an explosion-proof dehumidifier?

The explosion-proof dehumidifier uses explosion-proof motors, explosion-proof electrical components, and special structural design to ensure safe 

operation in flammable and explosive environments. Its core features include:

Explosion-proof certification: Complies with international explosion-proof standards such as ATEX, IECEx, or China's explosion-proof electrical 

equipment standards (such as GB3836).

Anti-static design: Prevents sparks generated by the equipment from igniting flammable gases or dust.

Corrosion-resistant materials: Suitable for corrosive environments such as those in chemical and marine industries.

Intelligent control: Can be equipped with humidity sensors, remote monitoring functions, etc., to achieve automated management. 

Which places must use explosion-proof dehumidifiers?

Petrochemical industry

Raw material warehouses and solvent storage areas in refineries and chemical plants may contain volatile gases (such as benzene, methanol), and ordinary 

dehumidifiers can easily cause explosions.

Areas around natural gas pipelines and LNG storage tanks need to prevent equipment corrosion and static electricity accumulation due to moisture.

Pharmaceutical and biological laboratories

The use environment of organic solvents such as alcohol and ether has a high concentration of flammable gases in the air, and must be equipped with 

explosion-proof dehumidifiers.

Sterile workshops and drug warehouses need to strictly control humidity, but electrical equipment must meet explosion-proof requirements.

Military and aerospace

Storage warehouses for gunpowder and ammunition are sensitive to humidity, but the environment is prone to explosive dust or gases, so explosion-proof 

dehumidification equipment is required.

In aircraft maintenance hangars, aviation fuel steam may accumulate, and explosion-proof dehumidifiers are needed to ensure safety.

Food and grain processing

When the dust in flour mills and sugar factories reaches a certain concentration, it may explode upon contact with sparks (such as dust explosion), and 

explosion-proof dehumidifiers are needed to control humidity and suppress dust.

The concentration of ethanol vapor in wine cellars is high, and traditional dehumidifiers have safety hazards.

Underground mines and tunnel projects

Methane gas in coal mines is prone to accumulate in damp environments, which accelerate equipment damage. Explosion-proof dehumidifiers can reduce the 

risk of gas explosion.

During tunnel construction, high humidity affects the solidification of concrete, but it is necessary to avoid electrical equipment causing combustible gas explosions.

Electronic and semiconductor manufacturing

The electrolyte vapor in lithium battery production workshops is flammable, and explosion-proof dehumidifiers are needed to maintain a low humidity environment.

Semiconductor clean rooms need to control humidity and prevent static electricity, but some processes involve flammable chemicals, and equipment must be 

designed with explosion-proof features. 

How to choose an explosion-proof dehumidifier?

Determine the explosion-proof level: Select the corresponding explosion-proof standard (such as Ex dⅡBT4) based on the hazardous substances (gases/dust) 

present in the location.

Calculate the dehumidification capacity: Choose the appropriate capacity (such as 30L/day, 100L/day) according to the space volume, target humidity, and 

environmental temperature.

Additional features: Do you need a drainage pump, remote monitoring, automatic defrosting, etc.? 

Conclusion

Explosion-proof dehumidifiers are an important guarantee for the safe production in high-risk industries. They can precisely control humidity and eliminate the 

risks of fire and explosion. When purchasing, enterprises need to strictly verify the explosion-proof qualifications of the equipment and conduct regular maintenance 

to ensure long-term reliable operation.
