ABSTRACT:
An air-cooled multi-stage compression system using centrifugal compressors is disclosed. It is packaged in a comparable volume to a water-cooled unit having the same driver horsepower. The performance is comparable and opportunities for use of the waste heat are available. Existing water-cooled units can be retrofit to run in an air-cooled mode. Special applications such as combined air compression and nitrogen compression useful in air separation applications are presented. The circulating cooling air can make the unit into an air filter of its surrounding space. Cooling air is drawn through the enclosure before being forced through the coolers above. This air movement can cool compressor housings, the control panel and the drive motors mounted in the enclosure.
