Required drying performance can only be achieved when following the defined operating
conditions!
Drying performance will decline and the achieved dew point will drop if the dryer is operated
at any pressure below the minimum working pressure!
Dryer operation at a pressure of 0.5 Bar below the minimum working pressure can lower the
dew point at the outlet by more than 10°C!
Drying performance will decline and the achieved dew point will drop if the dryer is operated
at any temperature above the maximum working temperature!
2. PRODUCT DESCRIPTION
A pre-filter and micro-filter are installed in front of the membrane dryer in order to capture solids and condensate
and prevent the membranes from being contaminated and to deliver compressed air of the expected quality. The
clean compressed air enters the membrane dryer and the module comprised of the bundles of membrane fibres.
As the compressed air is circulated against the hollow fibres, the water molecules are compressed against the
walls of the membrane and the outlet air is dry. Water vapour molecules that form of the walls of the membranes
must be removed. This is performed using some of the dry air exiting the module. This regeneration air is then
expanded to atmospheric pressure, removing the water vapour away from the dryer.
