Heatless Desiccant Dryers Handle Demanding Industries And Applications
Atlas Copco's three new high-performance desiccant air dryer ranges were designed for efficiency with low-pressure drops, delayed dryer cycles and a guaranteed constant pressure dew point -- even at full load -- under any condition.
The new products include two ranges of heatless desiccant dryers: the CD 25+-145+ and the CD 110+-300+. The CD+ range is engineered for reliability in harsh conditions. The third new range is the blower purge dryer, BD 100+-300+, which is built for energy efficiency and endurance. By using heated ambient air for regeneration, this dryer range can help reduce energy costs.
A desiccant air dryer protects production equipment and the quality of the end product by using desiccants to absorb moisture from the compressed air. These three new desiccant air dryer ranges are suitable for demanding industries and applications, such as electronics, food and beverage, pharmaceuticals, oil and gas and others.
The new CD+-BD+ series reduces energy consumption by optimizing the regeneration cycle. The CD+-BD+ series contains a pressure dew point sensor that 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. The Dew Point Dependent Switching delays dryer cycles, resulting in energy savings up to 90% when compared to more traditional switching systems, according to Atlas Copco.
