Abstract
Compressor controls in a compressed gas system provide a variable frequency controlled refrigerant compressor in a dehydrator for compressed air or other gases. The system detects changes in a demand on the pneumatic air supply by monitoring a pressure of a refrigerant system associated with the air supply. Based on the changes in the refrigerant system pressure, a motor speed controller generates and sends a control signal to the variable speed compressor to adjust the speed of the variable speed compressor based on the demand in the air supply.
