| CLEARPOINT® Housing model: O Compressed air runs through the core pipe, and is then diverted to the membrane element in the ground area. The compressed air, which is still humid, flows through the sharply selective hollow fiber membranes of the membrane element inside. © The purge air, required for drying, diverges continuously at the outlet area of the membrane element, and is expanded atmospherically using a defined nozzle orifice. Due to this expansion, the purge air becomes significantly dryer, as humidity contained in the compressed air now fills the expanded volume. The dry purge air passes the exterior of the membrane fibers. © As a result, two air flows with a different moisture content move in reverse flow through the membrane element, separated only by the membrane wall. Inside the membranes, humid compressed air flows and dry purge air passes outside. On account of the varying moisture content, moisture from the compressed air diffuses into the purge air. As regards the drying procedure, use of the TWIST 60 technology results in maximum efficiency. O Compressed air is dry when leaving the membrane element. © Humid purge air is released into the environment. |
