EVAPCO's 112-3N20 — an AT cooling tower, 696 nominal tons (3058 kW): rated to cool 2094 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 71.4 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.

BAC's VT0-19-G — a Series V cooling tower, 19 nominal tons (83 kW): rated to cool 57 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 2.9 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. 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.

EVAPCO's 12-4N36 — an ATWB closed-circuit cooler, 870 nominal tons (3825 kW): rated to cool 2182 USGPM of process fluid from 102 to 90 °F at a 75 °F entering wet bulb on 123.0 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. 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.

Baltimore Aircoil's VCL-073 — a Series V EC evaporative condenser rejecting 314 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 7.2 m³/s of the maker's own printed air, with a 3.7 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.
