Refrigerated air dryers typically work well when they are new. However, for a variety of reasons, over time their effectiveness diminishes. These reasons are dust collecting on condenser coils, It's not unusual to find dewpoints in the 50-60F range or higher, especially during the summer months. Our customers have complained of moisture contamination. Most factories live with this problem, thinking that nothing can be done. "Our air lines just have water in them. There is nothing that can be done."
Enter the Parker Membrane air dryers. These dryers are rated for a +35 pressure dewpoint with a 100F saturated feed stream. If these dryers are placed after a refrigerated air dryer, the dewpoint remains a steady +15 and often lower.
