The present study examines the cooling system of an air compressor, aiming to reduce the overheating of the machine. Due to this warming, it was required a new design for the cooling system with an increased power water pumping and energy consumption of the process. Nevertheless, the purpose of this study was to analyze the current process, to identify the causes of the overheating of the compressor and evaluate the design of the cooling system. A preliminary hypothesis was established and necessary tests were carried out. From the preliminary hypothesis, the analysis led to a change in the current installation, it means, to the addition of a control valve on the water pipe of the dryer, parallel to the compressor pipe. Thus, the compressor started to operate within the recommended temperature range, eliminating the risk of failure due to overheating, with improved life expectancy. This modification also led to reduction in energy demand water pump cooling and thus reducing the power consumption of the whole process.
