Case Study: York International Agency achieves early chiller bearing fault detection with SymphonyAI ExpertALERT

ExpertALERT™ automated diagnostics performance 210 TON York air conditioning chiller

York International Agency needed a reliable way to monitor a 210-ton York air conditioning chiller under a service agreement for the University of Pennsylvania power plant. To support this machine condition analysis, York selected SymphonyAI Industrial and used its ExpertALERT™ automated diagnostics performance service to assess vibration data from the motor, gearbox, and compressor assembly.

SymphonyAI Industrial’s ExpertALERT™ system identified serious compressor journal bearing wear and recommended inspecting the compressor bearings for proper clearances, assigning a Medium priority. The diagnosis was validated by manual analysis, and the chiller failed three weeks later on September 22, with technicians finding worn journal and thrust bearings plus badly damaged gears, showing SymphonyAI Industrial’s early warning capability and accurate fault detection.
