Refrigerant Dehumidifiers

These are the most popular dehumidifiers in today’s market, which work through drawing moist air to the dehumidifier and passing it over the cold evaporator coil.

This coil cools the air past the dew point, which is the atmospheric temperature below in which water droplets start to form.

This causes condensation and this water may be removed manually or can be purged through the hose to the dehumidifier. Then, newly dried air is released back to the room.

Desiccant Dehumidifiers

Desiccant is basically a hygroscopic substance that’s widely used for drying. These dehumidifiers work through running moist air through the rotor that has moisture absorbent desiccant material.
