Atlas Copco has introduced a new line of portable desiccant air dryers designed to deliver clean, dry air in challenging environments. The lineup includes six models: three twin tower dryers (CDR 850, CDR 1200, CDR 1700) and three versions incorporating solid desiccant technology (CDR+ 980, CDR+ 1350, CDR+ 1700).
These dryers are built to support a variety of mobile applications by delivering a steady flow of moisture-free compressed air. The systems are suited for use across rental fleets and in industries such as pipeline maintenance, offshore drilling, shipyard sandblasting, and construction.
Each unit offers a stable dew point of -40°C/-40°F to help protect downstream tools and equipment from damage caused by corrosion, freezing, or contamination. Operating pressures range from 7 to 16 bar (100 to 232 psi), with air delivery capacities between 24 and 48 m³/min (850–1700 cfm).
Two Technologies for Varied Needs
The CDR series uses traditional activated alumina desiccant, with pneumatic controls that eliminate the need for external power—an advantage in remote locations or on temporary job sites.
The CDR+ series incorporates Atlas Copco’s solid ceramic desiccant, Cerades™, designed to reduce pressure drop and energy consumption while extending service intervals. These models also come equipped with features like an integrated water separator, inlet filter, purge flow control, and a digital controller for monitoring system performance.
Built for Tough Conditions
All models are housed in corrosion-resistant frames and are designed to perform in temperatures ranging from -25°C to 50°C (-10°F to 122°F). The compact and mobile design supports quick setup and operation without specialized training or tools.
With the addition of the CDR and CDR+ dryers, Atlas Copco expands its portfolio of mobile compressed air solutions to include air treatment systems that complement existing compressors, boosters, and nitrogen generators.
