Atlas Copco CD Series Heatless Desiccant Air Dryer

The Atlas Copco CD Series Heatless Desiccant Air Dryer includes a constant pressure dewpoint of -20 °C/-5 °F or -40 °C/-40 °F as standard. The pressure dewpoint can be adjusted for seasonal or application changes. The large pipe diameter minimizes pressure drop to save energy. An electronically-operated 3/2 valve reduces the risk of breakdowns and provides control during airflow fluctuations. The strainer design minimizes pressure drop, regeneration times and energy consumption. 

The control panel includes a 4-line display in 23 languages, with service alarms and general alarm relay. The control system allows for synchronization with the compressor, turning on and off when the compressor does, and includes service indications (4,000, 8,000, and 40,000 hours) and warnings. Desiccant bags allow for quick replacement without spilling adsorbent material. A spring covers the bags to prevent damage by desiccant moving due to pressure pulsations. 

A PD pre-filter prevents oil contamination to increase desiccant lifetime and is included for installation in the air piping. A DDp after-filter protects the airnet from desiccant dust and network contamination and is included for installation in the air piping. The nozzle purge set offers flexibility in optimizing regeneration pressure for lowest purge air consumption. Standard is 7 bar.
