Desiccant compressed air dryers (also known as Regenerative
Desiccant Dryers) run the compressed air through a chamber
filled with desiccant, usually activated alumina or silica gel. The
desiccant adsorbs the moisture in its millions of pores, trapping
it. If the air dryer is using a smart controller the compressed air
dryer changes chambers when the dew point downstream begins to
change, indicating the desiccant is wet. Other models change on a
set timer. The wet desiccant is regenerated, or dried, by the
compressed air dryer's hot purge air. The hot air drives off the
moisture preparing the desiccant for its next cycle.
