1. A compressed air dryer system, the system comprising:
a plurality of dryer modules, each of the plurality of dryer modules configured to direct a portion of a cooling medium through a heat exchanger, the heat exchanger configured to transfer heat from a portion of compressed air to the portion of the cooling medium, each of the plurality of dryer modules including:
a temperature sensor in thermal communication with the portion of cooling medium, and
a chiller configured to reduce a temperature of the portion of cooling medium when the sensed temperature exceeds a temperature set-point; and
a controller communicatively coupled with the plurality of dryer modules, the controller operable to monitor a plurality of run-times, each of the plurality of run-times associated with a corresponding one of the plurality of dryer modules, the controller operable to regulate each of the plurality of run-times by modifying the temperature set-point of the corresponding one of the plurality of dryer modules.
