Adsorption Dryer

Atlas Copco’s CD+ heatless desiccant dryers protect your systems and processes. Their robust design ensures they operate with total reliability and deliver a constant, stable dewpoint in full load conditions and even during a temporary overload. The result is dry and clean compressed air for a broad range of industrial applications.

Technological innovations ensure that air is produced reliably and cost-effectively. Our CD+ dryers are available in a range of sizes with a guaranteed dewpoint down to -40°C/-40°F (optionally -70°C/-100°F), and come in an IP54 protected cubicle.

Customer benefits


High reliability

Atlas Copco’s CD+ desiccant dryers eliminate system failures, production downtime and costly repairs by removing moisture from compressed air with a pressure dewpoint as low as -70°C/-100°F. Up to 30% desiccant overfill and the long lifetime of the desiccant further enhance reliability.


Maximum energy savings

CD+ dryers incorporate energy-saving features that cut your carbon footprint. A low pressure drop below 0.2 bar/2.9 psi drives down energy costs. Dewpoint sensing and control adapts the energy consumption to the real load of the dryer.


Easy installation

Your CD+ dryer is delivered ready for use with silencers, sensors and the control unit already wired and connected.


Advanced control and monitoring

The advanced Elektronikon® control and monitoring system takes continuous care of your CD+ dryer to ensure optimal efficiency.


Minimum maintenance

All internal components are easily accessible to facilitate maintenance. The use of high-grade desiccant and durable valves extends maintenance intervals beyond the standard three years.



A proven, rugged design for the switching valves, the most important moving components in the dryer, significantly improves the lifetime of your CD+ dryer.
