American Cooling Tower ACC-66C cooling tower (55 tons, 241 kW) — modelled
Modelled from the manufacturer's published data — not verified by American Cooling Tower. Source: American Cooling Tower ACC Series catalog, page 5 — the model's own row (nominal tons, fan motor HP, airflow in CFM, length and height) and the sheet's own note: nominal tons are 3 gpm cooled from 95 °F to 85 °F at a 78 °F wet bulb. Its second condition is the line's own CTI 49-point table, which the model reads at 0.12 K RMS over 538 points with the line's own fill-loading exponent (docs/american-cooling-tower-source.json). The figures below come from this model run against that data; the manufacturer has not reviewed them. Are you American Cooling Tower? Claim this page.
CTI STD-201 (validation C38E-25R00) ✓ 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.

American Cooling Tower's ACC-66C — an ACC cooling tower, 55 nominal tons (241 kW): rated to cool 165 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 9.0 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 American Cooling Tower. Published as an example; the figures below are solved from this model.
