210 TON York air conditioning chiller

Vibration data was taken at the free end of the motor and at the gearbox end of the compressor. The data was collected in all
three axis- axial, radial (vertical) and tangential (horizontal), over two frequency ranges. A low, narrow band range from 0 to 600 Hz provides a good resolution of the first 10 harmonics of the motor shaft rate and the first three harmonics of the compressor shaft.
