An apparatus and method are provided for using logic to analyze the performance of a gas dryer system having dual dryer towers charged with desiccant. The apparatus and method utilizes sensors to sense the moisture content of gas entering into, discharging from, and recirculating within the dryer and also utilizes a flow meter to sense the flow rate of moisture remove from the desiccant during the regeneration mode. The apparatus and method determine when the dryer towers should be switched between their adsorption and regeneration modes and detects sensor malfunctions, desiccant problems, and water leaks.
