Desiccant dehumidifiers have many commercial and industrial applications. Their ability to process large volumes of air gives them a huge advantage of over refrigerant style units. Desiccants can be used in oil refineries, manufacturing facilities, painting booths, food processors and many other applications.
Desiccants work by pulling air through an absorbent material that pulls the water out of the air and the dry air is then returned to the area you are wanting dry. Then the absorbent material will rotate through a heating element and once it is heated it will release the moisture it has collected. The warm humid air, or reactivation air, will need to be vented to the outdoors.
Sizing a desiccant dehumidifier to your specific application is important to its ability to perform as expected. When trying to figure out what size of unit you will need, you will first need to know how many cubic feet of air is in the area you want dried. You will then need to know how the space is used. By this I mean does it have high humidity constantly or only during a certain point in the manufacturing process. Also, what is the temperature and relative humidity when the area is at its most humid? Once you have all this information then you will be able to have a dealer help you figure out the type and size of equipment that will meet your needs. Depending on the application you might need to have anywhere from 2 – 5 air changes an hour through your dehumidifier to achieve the results you desire.
So when you are drying a large area or have specific drying needs consider a desiccant dehumidifier.
