DESICCANT DRYERS

DESICCANT DRYERS

Desiccant dryers use a granular absorbent chemical to take moisture out of the air. This chemical process produces air that is much dryer than air that from a refrigerant dryer. Typically desiccant dryers produce air with a dew point of -20°C to -40°C. Desiccant dryers are more costly to buy and operate and require larger compressors to be specified since there is a certain amount of air loss in the regeneration process of the absorbent chemicals. Zero loss dryers are available.

Air with a dew point as low as -20’C or -40’C is only required for specialist applications, such as certain food and pharmaceutical applications. Air of this quality is also sometimes needed for lab work and extreme paint spraying applications.

Desiccant dryers are usually required in applications where very high quality air is required, such as in food, electronics and pharmaceutical industries and sometimes in high quality paint spray applications.
