57AbstractABA railway air dryer that switches the flow and counter flow of air through each of two desiccant towers (46, 48) in response to the actual humidity of air being dried by the air dryer. The air dryer includes a humidity sensor (68), a temperature sensor (72) in the outlet air, and a temperature sensor (50) in the inlet air stream to determine when to initiate the regeneration of the desiccant. The air dryer system is generally specified to provide some minimum drying performance, for example 40 °C dew point suppression.
