ABSTRACT:
A system and method for controlling the temperature of the compressed fluid flowing through a compressor aftercooler. The system includes a compression module flow connected to an aftercooler and at least one repositionable fluid flow regulating member upstream from the aftercooler for modifying the volume of ambient fluid supplied across the aftercooler. The system further includes a temperature sensor for sensing the ambient temperature, and an actuator connected to the at least one fluid flow regulating member. A controller is in signal receiving relation with the temperature sensor and is in signal transmitting relation with the actuator. If the sensed ambient temperature is outside a predetermined range, a repositioning signal is sent by the controller to the actuator, extending or retracting the actuator the amount required to achieve the required fluid flow rate across the aftercooler and thereby maintain the desired aftercooler fluid discharge temperature for the ambient operating temperatures.
