AD Series Dehumidifying Dryers
AEC dryers force hot, dry air through the resin in the drying
hopper, where the air picks up moisture from the material and is
drawn back to the dryer.
In the dryer, a desiccant bed strips moisture from the air. The dried
process air is then re-heated and delivered back into the drying
hopper to regenerate and cool the desiccant.
A small amount of ambient air is introduced into the process air
stream to make up for the air lost during the bed regeneration.
Because the process air is typically much drier than the ambient
air, the air mixture maintains drying efficiency at a consistently
high level. To compensate for the humidity content in the air, this
dryer is supplied with the proper amount of desiccant.
