EVAPCO's 29-4J21 — an AT cooling tower, 545 nominal tons (2397 kW): rated to cool 1641 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 52.2 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 VCA-623A — a VCA evaporative condenser rejecting 2684 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 53.3 m³/s of the maker's own printed air, with a 22.4 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.
