Atlas Copco Introduces CD Heatless Desiccant Dryers

Atlas Copco is introducing the CD+ 25-260 and the CD 25-260, two new dryer ranges designed for flexible compressed air solutions. The heatless desiccant dryers increase efficiency and reliable operation, even in harsh conditions.

 Atlas Copco CD+25

The CD+ 25-260 and CD 25-260 are available in inlet capacities from 50 cfm to 550 cfm.


The CD+ delivers the highest efficiency for applications requiring a constant supply of dry compressed air. It offers minimal purge loss and pressure drop at a constant pressure dew point of -40 °F or as low as -100 °F with standard configurations. The CD 25-260 provides a constant pressure dew point of -40 °F.

The new CD+ and CD are available in inlet capacities from 50 cfm to 550 cfm so customers can select an option meeting their specific needs. While most dryers only work at 70% to 80% of their capacity, the CD+ and CD are designed to reliably perform at 100% airflow.

The CD+ and CD come with a revolutionary type of manifold. Its electronically operated 3/2 valve ensures dependable tower switching, even during changing flow conditions. With large flow paths, the units offer a very low-pressure drop – below 2.9 psi for most models. Its novel strainer with “swirl” technology distributes optimal airflow from the manifold and decreases uneven wear of the desiccant. 

A state-of-the-art digital control system is included with optional Pressure Dew Point Control (PDP Control), able to synchronize the dryer and air compressor. With PDP Control, a dew point sensor can delay switching towers until necessary, generating energy savings up to 90%. 

Built for ease of use and flexibility, the CD+ and CD are suited for applications with a high inlet air temperature and outdoor weather-protected installations. They come with desiccant bags allowing for quick replacement and outside service panels for easy maintenance. The CD+ and CD also also include optional nozzles for optimizing the regeneration pressure to a customer’s process.

The CD+ 25-260 and the CD 25-260 are available worldwide and will replace the CD+ 25-145, CD 32-190.
