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

о

(

REGENERATION 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 

(

MOIST AIR

) 

which is discharged outside the dehumidified loop.

· 

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

.

о

· 

The rotor is reactivated by another air flow preheated to 

120 C. 

The moisture is removed from the room 

in the form of moist air.
