Are you sure you dont mean Windrock recip compressor piston analysis, we have used this to measure the pressure and swept volume on recip compressors to give us a health heck on valves and ring problems. I was not aware that they did vibration analysis aswell, for vibration analysis on recip compressors theres so much vibration wwe tend to use independents such as TTI.
If you mean the piston analysis our experience is it is a good tool to decide what maintenance is needed upcoming on recips.
