Dehumidification

Dehumidification

A dehumidifier is a device that removes moisture from the air to reduce humidity. Reducing humidity promotes a faster dry out. Building materials such as drywall, flooring, carpets and furniture will dry faster.

Dehumidifiers are important to stabilize the environment after a water damage event. They are important tools especially in high humidity areas where the air usually carries a lot of moisture.

Refrigerant Dehumidifier
A refrigerant dehumidifier circulates moist air through cold coils that reduce the temperature to the saturation point where moisture condenses and then collected into a bucket. A high capacity refrigerant dehumidifier can remove about 5 gallons in 24 hours. The main disadvantage is that performance deteriorates as the air becomes cooler.

Desiccant Dehumidifier
This dehumidifier uses a desiccant to remove water from the air and reduce humidity. The desiccant is a material with high affinity to water vapor.
  • Absorbent desiccants absorb water as they go through chemical or physical changes.
  • Adsorbent desiccants do not change when absorbing water. These desiccants hold moisture on their surfaces.
