desiccant dryers are designed to remove moisture vapour from compressed air.
The dryer comprises of an inlet and outlet manifold joined together by an aluminium column. The column has two internal chambers filled with
desiccant material. During operation one chamber is on-line (drying), whilst the opposite chamber is regenerating. This process is known as
Pressure Swing Adsorption (PSA).
Pressure Swing Adsorption (PSA)
A small percentage of dried air is taken from the dryer output flow and is used to regenerate the saturated chamber by expanding the dried air from
line pressure to atmospheric pressure. During this process, the moisture is physically removed from the regenerating chamber and vented to
atmosphere through the exhaust silencers.
Dewpoint Dependent Switching (DDS)
DDS will adjust the dryer’s cycle in line with the moisture loading placed upon it, by constantly monitoring the processed air moisture
content.
