Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Source: Baltimore Aircoil Product & Application Handbook volume VI, Series 1500 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 C11F-92R20) ✓ 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 S15E-1218-11LN — a Series 1500 cooling tower, 653 nominal tons (2870 kW): rated to cool 1965 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 70.2 m³/s of air, the maker's own printed airflow, and drawn at those flows with an induced-draft fan on the leaving air, pulling through the fill. Open fill: the water meets the air directly — Braun's enthalpy-basis tower model. The model derives the machine's NTU from that one certified point, so it reproduces the rated leaving water 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.
