What is Predictive maintenance?
Predictive maintenance schedules repairs from trends in equipment condition data, such as vibration, temperature or current draw, so work happens before a failure rather than on a fixed calendar or after a breakdown.
Where it pays back
The approach suits critical rotating and refrigeration equipment where an unplanned stop is expensive: chillers, compressors, pumps, fans and air handlers in hospitals, data centers, airports, manufacturing lines and dairy cold chains. Reliability engineers and facility managers use it to move discretionary work to the moment the data says it is needed.
Savings reported by DOE
The DOE FEMP Operations and Maintenance Best Practices Guide, Release 3.0, estimates that predictive maintenance saves 8 to 12 percent over preventive maintenance, and 30 to 40 percent where a site relies heavily on reactive repair. The industry surveys it cites for working programs report 25 to 30 percent lower maintenance cost, 70 to 75 percent fewer breakdowns and 35 to 45 percent less downtime.
Signals Aqueduct trends per asset
aQ Core onboards anything that emits telemetry, now including vibration and acoustic sensors next to power meters. aQ PredictIQ trends those signals per asset, and the electrical twin adds a second view: a motor drawing more kVA for the same duty, or a feeder whose power factor slips, can show wear before a breakdown.
