Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Source: Baltimore Aircoil Product & Application Handbook volume VI, Nexus 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: the line, not this model — Baltimore Aircoil's Nexus (NXF Series) line is certified (validation C11Q-18R02), but this model is not named in the disclosure that covers it, so nothing is claimed for it here: the disclosure names the H1 and J1 fan designators of each NXF cabinet (and H2 on one variant) where the engineering data prints H1–H6 and J1–J6; the rest are not in it. What the model of it reads against the maker's published tables is a separate question.

BAC's NXF-0403N-CS2TT-H6 — a Nexus closed-circuit cooler, 120 nominal tons (526 kW): rated to cool 360 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 23.8 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. 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.
