Predictive Maintenance

ML models predict remaining useful life for critical components -- bearings, seals, motors, and impellers. Know what will fail, when it will fail, and what to do about it.

Maintenance Strategy ROI

Predictive maintenance cuts total cost of ownership by 55% compared to reactive.

Reactive

Cost Index: 100%
Downtime: Unplanned, 8-24 hrs
Parts: Emergency pricing (+40%)
Risk: High risk of secondary damage

Preventive

Cost Index: 75%
Downtime: Scheduled, 2-4 hrs
Parts: Standard pricing
Risk: Over-maintenance of healthy parts

Predictive (TwinEdge)

Cost Index: 45%
Downtime: Planned, 1-3 hrs
Parts: Pre-ordered (-10%)
Risk: Replace only what needs replacing

Core Capabilities

Days of Lead Time

Predict failures 7-60 days in advance. Enough time to order parts, schedule crews, and minimize production impact.

RUL Estimation

Remaining Useful Life displayed as days, confidence interval, and health score. Track degradation trajectory over time.

Failure Mode ID

Models identify the specific failure mode -- bearing inner race, seal face wear, insulation breakdown -- not just "something is wrong."

Maintenance Windows

Algorithm recommends optimal maintenance windows that balance remaining life, production schedules, and crew availability.

Predict Failures Before They Cost You

Cut maintenance costs by 55%, eliminate unplanned downtime, and extend equipment life with ML-driven predictions.
