Desiccant Air Dryers

Desiccant air drying entails running moisture saturated compressed air over a bed of desiccant – typically made of activated alumina. During regeneration moisture is purged from the desiccant bed using the compressed air. Moisture adheres to the surface of the desiccant. Heated dryers use heat and ambient air instead of compressed air to regenerate.


The energy efficiency of the types of desiccant dryers varies based on purge air consumption. Typically, blower purge is 2.5%, heated is 7%, and heatless 15%.
