Technology: How does a Desiccant Dehumidifier work?

Consorb - DC units

More traditional system commonly used by other manufacturers because of its simplicity. This principle is best used at lower regeneration temperatures typically where waste heat is available or where the air inlet moisture content is very high.

Used in balanced ‘closed’ type systems where the dry process air is recirculated.

Aquasorb - A30 units

Aquasorb basically functions as a Consorb but moisture in the wet air is condensed through an air cooled condenser. One centrifugal fan is used for both the dry air and the condenser cooling air, so all energy released during the process accumulates in the dry air outlet.

Commonly used where it is impractical to use ducting for the reactivation air system.

Recusorb - R, RL & RZ units

Complete with internal heat recovery to improve operating efficiency. Heat transferred to the rotor during regeneration is effectively recovered by the incoming regeneration air, thus reducing the amount of energy required by the regeneration heater. The process air outlet is both cooler and drier when compared to other desiccant dryers. Most of our dehumidifiers operate on this principle.

Can be used on both ‘open’ and ‘closed’ type systems.

Recusorb - DR units

With internal heat recovery, DR is similar to the Recusorb R. For simplicity, both the process and reactivation airflows are provided by one pushing fan.

Used for introducing dry fresh air into a process or to an ‘open’ or ‘total loss’ system where the dehumidified air is ducted into the object.
