Abstract
A control system for an air dryer that switches the flow and counter flow of air through each of two desiccant towers in response to a drying cycle period that is proportional to the saturation partial pressure of water vapor in the inlet air stream as determined by the temperature of the stream of air in the inlet of the air dryer. The system may also include a proximity sensor positioned in the back flow check valve between the first main reservoir and the second main reservoir to further adjust the regeneration cycle period according to the flow rate through the air dryer.
