Operation principal

The dehumidifier works with two air flows.

 

The

 

volume of the dehumidified air is bigger. The

 

air 

flow of a smaller volume is used for moisture removal from the dehumidifier rotor

The rotor is 

subject  to  the  action  of  different  oppositely  directed  air  flows  by  sectors.  The  air  flow  to  be 
dehumidified 

(

PROCESS AIR

)

 passes through the biggest sector

The moisture from the air is 

trapped (adsorbed) by the rotor material. The air leaves the rotor in dehumidified condition 

(

DRY 

AIR

and  is  directed  to  a  certain  part  of  the  building  or  a  technological  process  where 

dehumidified air or a certain air humidity levels are required

Since the rotor rotates slowly the 

incoming  air  always  contacts  with  the  rotor  active  part,  thus  a  continuous  dehumidification 

 

process is assured.
The air flow used for the rotor matrix regeneration is called regeneration air

 (

AIR

). 

It is heated up to 

120 С 

and when passing through a small sector it removes the moisture 

trapped by the rotor material. The moisture is removed from the rotor in the form of humid air 

(

The air to be dehumidified passes through the rotor. Water molecules are absorbed by the rotor

The rotor is reactivated by another air flow preheated to

The moisture is removed from the room 

in the form of moist air.
