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.
