CDR 850, CDR 1200, CDR 1700
Ideal for pipeline work, offshore and shipyard operations, drilling, backup air, and rental applications
Atlas Copco’s CDR series delivers robust compressed air treatment for industrial, offshore, and remote applications. These twin tower desiccant air dryers ensure reliable moisture removal with a consistent dew point of -40°C/-40°F, safeguarding your equipment from corrosion, freezing, and water-related failures.
Operating within a pressure range of 7–16 bar (100–230 psi) and flow rates up to 80 m³/min (2754 cfm), the CDR dryers are engineered to perform under pressure—literally. Whether used in pipeline purging or remote drilling, they provide a consistent supply of dry air essential for high-performance air treatment solutions.
