EVAPCO's 112-3I14 — an AT cooling tower, 343 nominal tons (1507 kW): rated to cool 1032 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 36.2 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.

BAC's NXF-0603N-CS2TT-J2 — a Nexus closed-circuit cooler, 60 nominal tons (263 kW): rated to cool 180 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 12.2 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. 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.

EVAPCO's 12-3O20 — an ATWB closed-circuit cooler, 486 nominal tons (2137 kW): rated to cool 1219 USGPM of process fluid from 102 to 90 °F at a 75 °F entering wet bulb on 72.8 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.

Baltimore Aircoil's PCC-0117-0709N7.5 — a PCC evaporative condenser rejecting 711 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 16.9 m³/s of the maker's own printed air, with a 5.6 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.
