How KLVIN S.A.M.v3 devices, the SENTINEL IIoT platform and KAIROS AI reports detected a developing vibration anomaly on a critical rotating asset — enabling a planned maintenance intervention that prevented an unplanned breakdown at a continuous-process steel plant.
About the Plant
Our client operates a continuous-process steel plant in India. The plant runs around the clock, and any unplanned stoppage directly translates into lost production that cannot be recovered.
Prior to the KLVIN deployment in February 2026, condition monitoring across the plant's rotating equipment was carried out through manual periodic checks. Vibration and thermal anomalies in such assets can develop over days or weeks before catastrophic failure, making them ideal candidates for AI-powered condition monitoring.
KLVIN Deployment
KLVIN deployed S.A.M.v3 smart asset monitoring devices across the plant's critical rotating equipment in February 2026. Each device captures dual IR temperature (surface + drive-end bearing), triaxial gearbox vibration and triaxial motor vibration — feeding continuous data into the SENTINEL cloud platform and the KAIROS AI reporting engine.
Two Key Events — March to May 2026
Across the first three months of deployment, SENTINEL data and KAIROS reports surfaced two significant events. The first demonstrates what predictive maintenance intelligence delivers when acted upon. The second illustrates the financial cost of an unplanned breakdown in a continuous-process steel plant.
Critical Asset — Vibration Warning in March, Preventive Action in April
Mar–Apr 2026 · Failure Prevented
The March 2026 KAIROS monthly report flagged a critical rotating asset as WARNINGwith a HIGH-priority action item. SENTINEL data showed a clear vibration escalation across the first two weeks of operation: gearbox vibration climbed from 1.65 g RMS (Mar 1–2) to 3.32 g RMS (Mar 10–14), with a peak of 4.85 g — a doubling in less than two weeks of run time. Temperature remained within normal bounds, making vibration the sole but clear early indicator.
KAIROS issued the recommendation: "Vibration escalation trend (1.65→3.32 RMS) — schedule bearing inspection immediately to prevent developing failure." By the April 2026 KAIROS report, the asset was classified as HEALTHY — consistent with a successful maintenance intervention between the two reporting periods.
Main Drive Asset — CRITICAL Alert, Breakdown Followed
May 2026 · 8-Hour Breakdown
KAIROS daily reports began flagging a main drive asset as CRITICAL from 2 May 2026. SENTINEL data showed vibration and thermal readings escalating beyond warning thresholds on one of the plant's highest-criticality rotating assets.
The asset subsequently failed, resulting in an 8-hour unplanned production shutdown. KAIROS had been monitoring and reporting the developing anomaly in the days preceding the failure.
Financial Impact Estimate
The estimates below illustrate the financial impact of both events using publicly available steel market data and standard industry benchmarks for downtime cost components.
Event 1 — Preventive Maintenance (March warning → April action)
- Lost production — prevented stoppage
- Emergency repair premium avoided
- Spare parts at planned pricing
- Thermal recovery and ramp-up loss avoided
Event 2 — Main Drive Breakdown (May 2026)
- Lost production — 8-hour shutdown
- Emergency repair and mobilisation
- Replacement components at emergency procurement
- Thermal recovery and ramp-up loss
- Secondary asset inspection — downstream stress
Summary — 2-Event Financial Picture
Acting on the March KAIROS warning saved an estimated ₹33.8 lakh. If the plant had also acted on the CRITICAL alert from May 2, the 8-hour breakdown and its ₹36.3 lakh cost would also have been avoided — bringing total protected value to approximately ₹70 lakh across three months of deployment.
Deployment Timeline
KLVIN Deployment — S.A.M.v3 Devices Commissioned
Smart asset monitoring devices installed across the plant's critical rotating equipment. SENTINEL platform activated. KAIROS daily and monthly reporting commenced.
KAIROS Flags a Critical Asset — WARNING
Gearbox vibration on a critical rotating asset escalates from 1.65 g RMS to 3.32 g RMS in under two weeks, peaking at 4.85 g. KAIROS issues a HIGH-priority advisory recommending immediate bearing inspection.
Preventive Maintenance — Failure Averted
April KAIROS report confirms the asset restored to HEALTHY status — vibration and temperature within normal bounds. Estimated ₹33.8L downtime cost avoided.
Main Drive Asset — CRITICAL Alert
KAIROS daily reports flag a main drive asset as CRITICAL. Vibration and thermal readings exceed alert thresholds, documented across multiple daily updates.
Main Drive Failure — 8-Hour Shutdown
The main drive asset fails, resulting in an unplanned 8-hour production shutdown. Estimated combined cost ~₹36.3 lakh. KAIROS alerts preceded the failure by several days.
Key Learnings
This case illustrates two sides of predictive maintenance in practice: what happens when anomaly intelligence is available and addressed early — and what an unplanned breakdown costs at a continuous-process steel plant.
