Description of the Related Art Generally, in a compressor used for dry gas other than an air compressor, leakage of cooler cooling water is detected by monitoring a dew point at a cooling device outlet. In the case of an air compressor, the water contained in the air is condensed by compression and comes out as a drain, so it is difficult to detect the leakage of cooling water from the cooler tube due to the dew point using only this water. However, automatic detection of cooling water leakage has not been performed.
