Source: Baltimore Aircoil Product & Application Handbook volume VI, Series V closed circuit engineering data — the model's own row (nominal tonnage, airflow in CFM, fan motor, dimensions) and the sheet's own rating note: a nominal ton is 3 USGPM of water cooled from 95 °F to 85 °F at a 78 °F entering wet-bulb temperature (docs/bac-source.json). The figures below come from this model run against that data; the manufacturer has not reviewed them. Are you Baltimore Aircoil? Claim this page.
CTI STD-201 (validation C11K-00R03) ✓ verified — this model is named in the certification programme's own public register. It certifies the manufacturer's machine against their published ratings; it says nothing about the model of it that runs here, which is validated separately.

BAC's VF1-144N-31R — a Series V closed circuit closed-circuit cooler, 148 nominal tons (648 kW): rated to cool 444 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 36.0 m³/s of air, the maker's own printed airflow, and drawn at those flows with a forced-draft fan on the leaving air, where its nameplate cannot be counted twice against a certified point. The process fluid runs inside a coil under the spray — the evaporative wet-coil model, its two conductances split as the range's own coil volumes say. The model derives the machine's NTU from that one certified point, so it reproduces the rated leaving process fluid exactly and predicts nothing else — one point per model is an input, not a validation. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.
