Up to now, the combination of energy-saving functionality of refrigeration dryers with the exceptional low-pressure dew points of desiccant dryers has only been cost effective for applications requiring large to very large volumes of treated compressed air. The new Hybritec compressed air dryer range (photo) is now available for free-air deliveries from 20 m3 /min. A refrigeration dryer at the input side ensures a consistent pressure dewpoint of 3°C with minimal energy consumption. After passing through the refrigeration dryer, the air flows into a desiccant dryer. Less energy is required for this second treatment stage in order to dry the compressed air to a pressure dew point of below – 40°C. — Kaeser Kompressoren GmbH, Coburg, Germany
