Compressed air dryers that use desiccants to get rid of moisture work well in a variety of situations. Compared to refrigerated air dryers, they can draw out more water vapor molecules from the air. In addition, they can perform well at a low dew point and are essential for high air quality in an industrial setting. Here is more information on why you should choose an air compressor desiccant dryer.
Desiccant Air Dryers VS Refrigerated Air Dryers
Although refrigerated air dryers can successfully take away water vapor from compressed air, they rely on a lower dew point. On the other hand, desiccant air dryers can perform in colder temperatures. Therefore they are more suitable for industrial processes that are highly sensitive to moisture.

They have over 25 years of experience in the air drying systems market and can match your needs with the best possible industrial equipment. Visit www.superdrysystems.com for more information.
Desiccant Materials Eliminate Moisture
Desiccant is a type of material that absorbs moisture extremely well. Desiccants contain hygroscopic properties that attract and retain water. Using these materials, air dryers can create a moisture-free environment. There are many types of desiccant materials. This includes calcium sulfate, calcium chloride, aluminosilicate minerals, silica gel, and activated charcoal. The latter two are common in these types of dryers, and they are chosen depending on unique industrial needs.
Silica Gel Desiccant Dryer
Most people are familiar with silica gel. Small silica gel packets are often included in dried food packages and other non-edible goods too. The moisture in the air that flows through the silica gel sticks to the surface. The water then absorbs into the silica gel until it becomes fully saturated.
Activated Carbon Desiccant Dryer
Activated carbon is incredibly porous and features a huge surface area that can retain moisture. Rather than silica gel, activated carbon is resilient and can be reused and regenerated. Activated carbon desiccant dryers with two towers are able to regenerate in one tower while the other continues to absorb moisture in compressed air. This regeneration process goes on continuously, making activated carbon desiccant dryers more efficient to run.
Regeneration
As mentioned previously, air dryers with two towers can regenerate once one tower has become fully saturated with water. The tower that isn’t in operation then goes into regeneration mode and begins to regenerate by using hot air, dry compressed air, or by using special drying systems.
Achieve Supremely Dry Air
Air compressor dryers that use desiccant materials can help you achieve ultra-dry air, including ISO quality classes 1, 2, and 3. They can also be used in below-freezing conditions for intermittent and continuous flow applications.
