DMD MODULAR REGENERATIVE DRYER
INTRODUCTION
The DMD range of compressed air dryers are
designed to remove moisture from compressed air
by utilising state of the art technology to obtain
dewpoints of -40°F PDP and by appropriate de-rating
-100°F PDP.
DMD dryers have been designed to require minimal
maintenance and can be installed virtually anywhere.
The DMD dryer consists of upper and lower head
assemblies joined together with an aluminium
extrusion containing twin internal chambers. The
upper head assembly contains inlet and outlet
manifolds. The lower head assembly contains two
exhaust valves and a passive shuttle ball valve.
During operation one chamber is on-line (drying)
while the other is regenerating, using the Pressure
Swing Adsorption (PSA) process.
P
RESSURE SWING ADSORPTION (PSA)
A small percentage of dried air is taken from the
dryer outlet 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.
