Predictive Maintenance (PdM)

Predictive maintenance uses sensor data and analytics to predict when equipment will fail, so maintenance happens just before failure — not on a fixed schedule and not after a breakdown. It cuts unplanned downtime and avoids unnecessary scheduled work.

Predictive maintenance (PdM) monitors the actual condition of an asset — through vibration, temperature, oil, ultrasound or process data — and uses analytics or machine learning to forecast failures before they happen. It sits between reactive maintenance (fix after failure) and preventive maintenance (fix on a calendar). The payoff is fewer surprise breakdowns and less wasted maintenance labour, focused on critical and high-cost assets such as pumps, motors, fans and compressors.
