Baltimore Aircoil's PCC-1244-2420N080 — a PCC evaporative condenser rejecting 7557 kW at a 40.6 °C condensing temperature and a 25.6 °C entering wet bulb, on 115.1 m³/s of the maker's own printed air, with a 59.7 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.

BAC's PFI-1218N-3D3ES-O1 — a PFi closed-circuit cooler, 248 nominal tons (1091 kW): rated to cool 747 USGPM of process fluid from 95 to 85 °F at a 78 °F entering wet bulb on 57.0 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. Modelled from the manufacturer's published data — not verified by Baltimore Aircoil. Published as an example; the figures below are solved from this model.

Open fill: the water meets the air directly — Braun's enthalpy-basis tower model.

A closed-circuit cooler from BAC's Series V range: the loop fluid runs inside a coil under a recirculating spray and never touches the air, which is what a process loop or a heat-pump condenser loop wants. Rated on the same basis as the open towers — 168 USGPM cooled from 95 to 85 °F at a 78 °F entering wet bulb — on 13.8 m³/s of air from a centrifugal fan, with a 1 hp spray pump and 111 gal of coil. Run as an evaporative wet coil: air against the falling spray, the fluid against the air, the two conductances derived from the rating at the split and fluid-side flow exponent BAC's own Series V closed-circuit performance table picks — 4 and −0.6, the spray film outside the tube being much of the fluid side's resistance.
