EVAPCO's 112-4L12 — an AT cooling tower, 452 nominal tons (1989 kW): rated to cool 1362 USGPM of water from 95 to 85 °F at a 78 °F entering wet bulb on 43.6 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-J6 — a Nexus closed-circuit cooler, 179 nominal tons (789 kW): rated to cool 540 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 36.5 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. 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 12-5M40 — an ATWB closed-circuit cooler, 913 nominal tons (4014 kW): rated to cool 2291 USGPM of process fluid from 102 to 90 °F at a 75 °F entering wet bulb on 117.9 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-0130-0709N7.5 — a PCC evaporative condenser rejecting 790 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 15.6 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.
