Air Compressor Sizing for High Ambient Temperatures

The approach temperature is a reference point on how close the compressed air discharge temperature is to the ambient temperature. Most air-cooled compressors have an approach to ambient temperature listed as 10°F (-12°C), 15°F (-9.4°C), or higher; it all depends on the size of the compressor and the rated design conditions.
