A dryer assembly for drying compressed fluid received from a fluid compressor. The dryer assembly comprises a compressed fluid circuit and a refrigeration circuit associated with the compressed fluid circuit and configured to reduce the temperature of the compressed fluid and to remove condensate from the compressed fluid. The dryer includes means for manipulating the dryer to regulate the rate of heat transfer between the compressed fluid circuit and the refrigeration circuit. A first sensor senses the lowest temperature of the compressed fluid after the compressed fluid has passed the refrigeration circuit and a second sensor senses a reference temperature. A controller is configured to receive the lowest temperature and reference temperature from the sensors and to determine a relative humidity based on the lowest temperature and the reference temperature. The controller controls the means for manipulating the dryer in response to the determined relative humidity.
