Atlas Copco CD 2-32 Heatless desiccant-type air dryers 

For critical applications where air quality is paramount, the Atlas Copco CD 2-32 range of heatless adsorption air dryers provides the perfect solution.

The outstanding installation flexibility of the Atlas Copco CD 2-32 range ensures that, regardless of the application, there is no solution more convenient. Perfect for both point-of-use and regular compressor room installations, these small units deliver a high performance with minimal maintenance.

The principle of the heatless desiccant dryers(reactivation by purge air) is based on the physical property of the desiccant to adsorb and adsorb water vapor. The dryer consists of two drying towers, one of which is in drying service while the other is under reactivation treatment.

All dryers are manufactured in accordance with Atlas Copco's Quality and Environment Management System. This system complies fully with ISO 9001 and ISO 14001. All Atlas Copco dryers are tested to perform under the most demanding conditions

Control and Monitoring

Timer-based control systems

The drying and regeneration process is controlled by a pre-set timer, which fixes the drying, regeneration and re-pressurization times so that the dryer works reliably under a wide spectrum of conditions.

To save purge air, the controller is equipped with a purge saver function, which allows the purge process to be interlocked with the compressor load/unload cycle
