Medical and Operating Rooms, Industrial and Food Process Dehumidifiers, Corrosion Prevention Dehumidifiers, and Low and Ultralow Depoint Dehumidifiers
Desiccant dehumidifiers provide a highly effective solution for removing moisture from the air in low temperature and low humidity environments. Desiccant dehumidifiers use a desiccant material that attracts and absorbs water vapor, removing moisture from the air.
Desiccant dehumidification systems are commonly used for applications below 45% RH down to 1% RH. They are well suited for applications where there is a need to independently control the temperature of the space and the moisture level or humidity of the space.
