EVAPCO's 424-2I28 — an AT cooling tower, 1155 nominal tons (5078 kW): rated to cool 3477 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 141.3 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 EVAPCO. Published as an example; the figures below are solved from this model.

A 600-ton counterflow Series V — centrifugal fans, forced draft, 1 800 USGPM cooled from 95 to 85 °F at a 78 °F entering wet bulb on 61.9 m³/s of air. Its liquid-to-gas ratio of about 1.6 is the highest of the five published here, which is why its derived NTU is the highest too: a counterflow tower works its fill harder per unit of air than a crossflow one. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.

EVAPCO's 424-2J24 — an AT cooling tower, 1323 nominal tons (5814 kW): rated to cool 3981 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 152.1 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.

BAC's VF1-288N-21Q — a Series V closed circuit closed-circuit cooler, 252 nominal tons (1108 kW): rated to cool 759 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 68.7 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.

Baltimore Aircoil's VCA-785A — a VCA evaporative condenser rejecting 3382 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 57.9 m³/s of the maker's own printed air, with a 33.6 kW fan. The heat comes from outside the drawing, because that is what this machine is: heat rejection, and the plant that sends it the heat is the customer's. Given exactly the rejection BAC certify, the model solves the condensing temperature the machine settles at — which is the reading, and the only figure here that is ours rather than theirs. The rating condition is an inference and the listing says so: BAC's sheets never define the condition of their Base Heat Rejection.
