Applications of Dehumidifier
Preair's dehumidifier adopts the principle of freezing and dehumidification, and the dehumidification technology is mature. The dehumidifier produced adopts the international brand compressor, which has high energy efficiency, good heat exchange, reasonable configuration and strong dehumidification. We mainly solve people's humidity troubles in four aspects.
1.The problem of dehumidification after the flood.
2.The humidity problem of green planting in greenhouses.
3. People are troubled by dehumidification in industry, such as warehouses, factory workshops, large real estate buildings and other places that need dehumidification.
4. Commercial dehumidification. Our dehumidifiers are widely used in underground garages, archives, conference rooms, power distribution rooms, swimming pools and many other industries, so that items can avoid major losses due to humidity during storage.
