Centrifugal Compressors

Centrifugal compressor monitoring, built on the data you already collect.

TruPrognostics AI diagnoses process and mechanical faults across centrifugal compressors and forecasts remaining useful life where the data permits. Process-domain analytics from your historian on day one. Frequency-domain analytics with a single vibration sensor where you need them.

Fault Coverage

Four example high-impact fault modes from our compressor coverage.

Loss of Efficiency (by stage)

Tracked against the expected operating map.

Polytropic efficiency degrades as internal clearances open up and seals wear. TruPrognostics AI tracks per-stage efficiency against operating point and produces a remaining useful life forecast at every tier.

Bearing Wear

Detected before mechanical damage.

One of the most common precursors to centrifugal compressor failure. Catchable in the process domain at Base; resolved with frequency-domain precision at Plus and Premium. Remaining useful life forecast at every tier.

Leakage (by stage)

Diagnosed from process data alone.

Worn or damaged seals let gas recirculate from the high-pressure side to the low-pressure side, reducing effective stage work. The signature shows up as a specific pattern of efficiency loss on the affected stage.

Oil Whirl

A precursor to bearing failure, diagnosed precisely.

Sub-synchronous vibration patterns characteristic of fluid-film bearings approaching their stability limit. Diagnosed with frequency-domain analytics on raw vibration waveforms at the Plus and Premium tiers.

The Approach

Process data first. Vibration where it earns it.

Centrifugal compressors are well suited to process-domain analytics. The relationships between pressures, temperatures, flows, and stage performance are well understood, and your historian already has the data.

TruPrognostics AI starts there. Detected anomalies are diagnosed against a library of fault-specific models, each calibrated to the physics of how the failure mode shows up in process variables. Where the data permits, the system also produces a remaining useful life forecast.

Each diagnosis ships with a recommended action, drawn from OEM manuals, customer SOPs and FMECAs, and prior work-order history. Every recommendation cites the source it draws from. Engineers keep decision authority; TruPrognostics AI does the analytical heavy lifting.

For mechanical and bearing-specific faults that don't surface cleanly in process data, a single high-frequency vibration sensor unlocks the frequency-domain analytics. One sensor, substantial diagnostic uplift.

The Tiers

Day-one value at Base. Mechanical precision at Plus and Premium.

Base

PI / historian process data. Stage efficiency, compression ratios, hydraulic performance. Catches efficiency loss, seal degradation patterns, and broad bearing decline.

Plus

Add one high-frequency vibration sensor on the bearing housing. Resolves bearing wear, oil whirl and whip, and mechanical signatures to fault-specific diagnoses.

Premium

Multiple high-frequency sensors. Maximum diagnostic precision on the most critical assets in your fleet.
