A World of Quality

UNA-DYN dehumidifiers, distributed exclusively by Seedburo, remove moisture from air by forcing it through beds of dry desiccant, a compound that will attract a high percentage of its own weight in water. When a bed of desiccant has removed all the moisture it can hold, it is dried or "reactivated" by blowing hot air through it.  While one bed is drying, the other is adsorbing moisture. This shifting from bed to bed is automatic and works in a continual cycle.

Humid air enters the dehumidifier at the humid air inlet. This air is filtered, and then flows through the desiccant bed where it is dried. It is then forced out the dry air outlet. At the same time, air is drawn into the dehumidifier at the reactivation air inlet. This air is filtered, forced through the valve, across the heater and then through the desiccant bed that has become damp. Here, the heated air removes the moisture and thus reactivates the bed. This air then flows through the valve and is exhausted through the reactivation air outlet carrying the moisture with it in the form of a vapor.

The A Series of dehumidifiers are also used for drying the "pocket" of air in the top of a bin or storage silo. Typically the dehumidifier is located in the silo skirt area.  Duct work is connected to the dry air outlet and humid air inlet to transport the processed air to and from the top of the bin or silo. In this manner, the dehumidifier prevents condensation in the bin or silo and reduces the overall relative humidity of the entire mass.
