What the report shows

Pages from a real CAS ASSiST assessment of a week of logged data. Every number, check and chart below was worked out by CAS ASSiST from the logs and the equipment register.

The plant is Sample Plant, a simulated three-compressor plant built from patterns seen in real assessments. No customer data.

The answer on page one

Scores for performance, efficiency, responsiveness and health, the key figures, and what to fix, ranked by what it saves. Savings that act on the same waste are counted once, never twice.

Executive summary: overall score 50, average demand 737 scfm, specific power 18.9 kW per 100 scfm, leaks 327 scfm, identified savings $30,590 a year, and a ranked list of what to fix by savings.

Every entry checked against the logs

Setpoints, nameplate data and ratings are checked against what the equipment actually did. Entries the data contradicts are flagged, and where the data settles it, the measured value is used. Here a setpoint and a nameplate rating didn't match the logs.

Entries Checked Against the Data: each entry, what the logs show, and whether it agrees or should be checked.

The system mapped step by step

The system is worked out in order, each step building on what has already been confirmed, from the logged readings through to demand and leaks. Every result says whether it holds, is worth a look, or is flagged, and why.

System Map, Each Compressor: each check marked holds, worth a look, or flagged, with the reason.

Problems no one entered

Problems that aren't in the equipment list still show up in the data. Here a dryer recorded as shutting down with the compressors kept running after they stopped, wasting stored air every shutdown.

System Map, Dryers, Purge and Drains: a dryer flagged for running with the compressors stopped.

The evidence behind each finding

Every recommendation points back to the logged minutes that prove it, so you and your customer can see it for yourselves.

Evidence from the Logs: pressure and power charts around each top recommendation.

Pressure lost on the way

The pressure each compressor loses on the way to the far end of the system, against what the installed equipment should lose, and what the difference points to. Every psi made only to be lost is energy that delivers nothing.

False Loading: each compressor's pressure loss to the far end of the system.

Which units should run at each demand

The arrangements of the compressors compared against the plant's real demand, with what each would save and what it asks of the machines.

Staging Ladder: the arrangements of the compressors compared, and which units run at each level of demand.
