How does a crawl dehumidifier work?

A crawl space dehumidifier extracts moisture from the crawl space and maintains the air dry. Air is sucked into the dehumidifier and passed over coolant coils. Here the moisture condenses and it is collected in the tray. The dry air is then pulled back to the crawl space. This process is done till the levels of humidity are below 50%.

Is there a difference between a normal dehumidifier and a crawl space dehumidifier? - Yes, the crawl space dehumidifier is designed to keep operating fully even at very low temperatures. In the winter when it is very humid the temperatures fall drastically. The crawl space dehumidifier is equipped with de-freezing features that allow it to keep operating even at 10 degrees.
