Dryer ranges maintain pressure dew point

January 10, 2011

Atlas Copco has launched three desiccant air dryer ranges designed for efficiency with low-pressure drops, delayed dryer cycles, and a guaranteed constant pressure dew point—even at full load—under any condition.

A desiccant air dryer protects production equipment and the quality of the end product by adsorbing moisture from the compressed air. These three new ranges are suitable for demanding industries and applications, such as electronics, food and beverage, pharmaceuticals, and oil and gas.

According to the company, the new series reduces energy consumption and lowers the carbon footprint by minimizing pressure drops and optimizing the regeneration cycle. A pressure dew point sensor measures the remaining humidity in the compressed air, detects when the active tower is completely saturated, and then switches the functions of the two dryer towers at the optimal moment. Because of the dew point-dependent switching feature, dryer cycles are delayed, which may result in energy savings up to 90 percent.

The products include two ranges of heatless desiccant dryers: the CD 25+-145+ and the CD 110+-300+. The CD+ range is designed to be reliable even in harsh conditions. The third range is the blower purge dryer, BD 100+-300+, built for energy efficiency and endurance. By using heated ambient air for regeneration, this dryer range helps to minimize energy costs, the company states.
