EVAPCO's 217-2H9 — an AT cooling tower, 323 nominal tons (1420 kW): rated to cool 972 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 38.5 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.

Baltimore Aircoil's CXVB-473-1224-20 — a CXVB evaporative condenser rejecting 2866 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 67.8 m³/s of the maker's own printed air, with a 14.9 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.

EVAPCO's 217-2I11 — an AT cooling tower, 407 nominal tons (1788 kW): rated to cool 1224 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 47.5 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 FXV-1212C-32Q-P — an FXV closed-circuit cooler, 265 nominal tons (1165 kW): rated to cool 798 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 51.5 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.
