Absorption Dryers

The right desiccant dryer for your application

A dry compressed air system is essential to maintain the reliability of production processes and the quality of your end products. Untreated air can cause corrosion in pipe work, premature failure of pneumatic equipment, and product spoilage. An Atlas Copco desiccant dryer produces dry compressed air in a reliable and energy-efficient way while protecting your systems and processes.


Desiccant dryers or twin tower dryers consist of two towers filled with desiccant such as activated alumina or silica gel. While one tower is drying compressed air, the other is being regenerated. Desiccant dryers can achieve dewpoints of down to -40°C/-40°F and -70°C/-100°F.
