Atlas Copco offers a wide range of desiccant air dryers to meet various industrial and commercial needs. Desiccant air dryers are used to remove moisture from compressed air to prevent damage to pneumatic tools, machinery, and other equipment, especially in applications that require dry and clean air.

The Atlas Copco desiccant air dryer range typically includes the following types:

1. Heatless Regenerative Desiccant Dryers: These dryers use two towers filled with desiccant material. While one tower is drying the compressed air, the other is being regenerated using a portion of dried air or an external heat source. The drying process alternates between the two towers, ensuring a continuous supply of dry air.

2. Heated Regenerative Desiccant Dryers: Similar to heatless dryers, heated regenerative desiccant dryers use two towers filled with desiccant. However, they employ a heated purge air stream to regenerate the desiccant in one tower, which can improve energy efficiency.

3. Blower Purge Desiccant Dryers: These dryers use a blower to provide the purge air for regeneration instead of using compressed air, which can result in energy savings.

4. Heat of Compression Desiccant Dryers: These dryers integrate with the compressor and use the heat generated during compression to regenerate the desiccant, eliminating the need for additional energy for regeneration.

5. Externally Heated Desiccant Dryers: These dryers use an external heat source, such as electricity or steam, to regenerate the desiccant material.

The specific models and technical specifications within each type of desiccant air dryer can vary, depending on factors like capacity, pressure requirements, dew point, and the type of desiccant used.
