Both issues were found through use of vibration analysis, which is an essential tool in predicting wear in chiller compressors and motors. We recommend taking vibration samples on chillers at least once a year, if not every quarter. Over time we can discover a trend of the life of wear components, preventing unscheduled down time and making repairs before major failure occurs. This is especially important in the Orlando, Central Florida market due to an almost constant heat load where unscheduled down time for a chiller can result in an uncomfortably hot environment.
