6Heatless Desiccant Dryers |Instruction Manual
Function of the Dryer
The dryer is designed to provide a smooth, controlled and
uninterrupted delivery of dry compressed air. Wet air passes
through a pre-lter and travels down to the bottom valve
assembly. The air is then fed through the bottom of the
desiccant bed and moves through the high performance
desiccant until it becomes dry. On exit from the desiccant
cartridge, the air is passed through the outlet valve assembly.
During this process, the dryer control system cycles the process
air between the two desiccant towers. While one chamber is
on stream removing water vapor, the other is being carefully
depressurized in preparation for regeneration. The desiccant
bed is regenerated by expanding a small amount of dry
process air, or purge air, through the saturated desiccant.
Purge air passes to atmosphere through the silencer, which is
tted to an exhaust valve. The chamber is then repressurized,
with the control system assuring each chamber is at full
operational pressure prior to changeover.
This ensures a reliable and efcient operation. The air stream is
switched and the cycle repeats on a continuous basis.
