Desiccant Dryers

Compressed air machines and air dryers go hand in hand. If your company uses compressed air, you are probably already aware of the importance of a reliable air dryer. What you might not be sure about is what type of air dryer you need. If you are trying to determine whether or not desiccant air dryers are what you need, read on.

What Do Desiccant Air Dryers Do?

Like other air dryers that companies use with compressed air, the purpose of a desiccant air dryer is to remove moisture from the compressed air in your facility. Air compression tends to create moisture and cause the air to reach its dew point faster. The result is condensation and unwanted liquid which can contaminate your work field. Desiccant air dryers remove this moisture and prevent contamination from occurring.

How Do Desiccant Air Dryers Work?

Unlike the more common refrigerated air dryers, desiccant air dryers do not work by cooling down the compressed air. Instead, they operate on a principle called adsorption. The desiccant air dryer contains an active desiccant material such as silica gel or activated alumina. This material actively pulls the moisture out of the air through adsorption, so it cannot condense and become liquid.

Desiccants regenerate their ability to adsorb moisture after use either through a heated purge (heated or blower purge dryer) or through a pressure-swing system (heatless dryer).

What Are Desiccant Air Dryers Used For?

You will want to use desiccant air dryers rather than refrigerated air dryers for highly-sensitive environments where the presence of any moisture could damage your equipment or product. Some examples may include the pharmaceutical industry when working with drugs that need to be extra-pure or when working in chemical manufacturing.

A few other areas you may also find desiccant air dryers include the food and beverage industry, naval operations and petrochemical businesses.
