Desiccant 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.
