ABSTRACT:
A compressed air system includes an electronic control which controls enabling and disabling of the compressor in response to pressure level variations in the system storage reservoir. A humidity sensor is installed in the system reservoir and generates a signal which varies as a function of the humidity of the compressed air in the reservoir. The control unit includes a comparator which compares the signal generated by the humidity sensor with a reference signal and generates a humidity control signal when the humidity of the air in the reservoir exceeds the reference level. The control unit responds to compressor disabling by causing the system air dryer to regenerate or purge for a predetermined time period, even if the compressor is unloaded for time periods greater than the predetermined time period.
