Applications Dehumidification by cooling or dessication has a variety of applications, including: Preventing moisture regain. Nearly all materials have some affinity for moisture based on surface characteristics and the amount of surface exposed to humid air. Moisture regain occurs when moist particles stick together. Preventing condensation. Air holds water vapor in proportion to its temperature. Cold...
