How Desiccant Dehumidifiers work
Click to Enlarge
Desiccant Rotor dehumidifiers remove the humid the air and provide the relative
dry air by a rotating desiccant silica-gel wheel, which is continuously re-dried
again. In this series, the most important component is the desiccant rotor. It is
formed as honeycomb, usually making of silica gel or molecular. When the process
air passes into the 3/4 flutes of the wheel, it is absorbed by the desiccant. At
the same time, a heated air stream， called the reactivation air, pass through the
1/4 flutes, warms the desiccant by evaporating the moisture within. Thus, the
desiccant rotor recovers the dehumidification capability.
How to select a suitable Desiccant dehumidifier?
The range of temperature of Desiccant dehumidifier can be applied is larger than
industrial refrigerate dehumidifiers. Greeme's Desiccant Dehumidifiers GMR Series
is in the range of -20℃ ~ 60℃.
To choose a suitable desiccant dehumidifier, you need to consider the following
Size & volume of your facility to calculate the required capacity.
Present humidity levels and the required humidity levels you need. We always
consider the base of on the worst case scenarios, also taking different climatic
conditions in different season into account.
Required humidity levels that you need to maintain regularly. This will depend on
the products being stored by you.
Any moisture source or temperature source is also needed to be concerned.
Any fresh air will transfer into the room
Any people will go into the facility
Based on the above data, we can calculate the required dehumidification capacity
and select accordingly. In some complicated cases, we need to know more details of
your facility and environment.
