Abstract
An aftercooler through which a first fluid passes. A cooling fan applies a cooling fluid to the aftercooler. A variable speed motor is rotatably coupled to the cooling fan. A temperature sensor, in communication with the first fluid, is located downstream of the aftercooler. A controller controls operation of the variable speed motor based upon the temperature applied to the temperature sensor to prevent condensate freeze-up.
