Abstract

See full text

A compressed air system includes an air dryer which includes a desiccant for drying compressed air passed through the desiccant before the compressed air is received in a storage reservoir. A humidity sensor is installed in the system downstream of the desiccant for measuring the relatively humidity of the air after it passes through the air dryer. A control module is programmed such that if the humidity level increases above 80%, a timer is started. If a time period of several hours elapses without the humidity level decreasing below 50%, a depleted desiccant and/or a system malfunction is indicated, and an appropriate warning device is actuated.
