KeepRite's KEZA150H8, the largest unit of its KEZ cooler range — a two-fan air-cooled scroll condensing unit — as this model runs it: the Copeland ZB114K5E its manual names — the catalog's own map — on R448A, an air-cooled condenser on the cabinet's face, its fins louvered for the enhanced tube and fin the manual names, and the two fans (1 560 W) that draw air through it. The condenser's airflow is the one figure fitted, on the manual's R404A cell nearest AHRI 1250's rating point (25 °F suction on a 95 °F day, 135 000 Btu/h), and it stands for the condenser's conductance, not for air: the 16 450 cfm it comes to takes about four times the air power the printed fans could give through that coil, so the fans could not move it — read at the compressor's own rating basis, the tables ask more of the condenser than this model's coil gives behind those fans. That same condenser holds all 214 cells the manual prints for this unit on R404A, R407A, R448A and R407C within −6.9 to +5.7 % (RMS 2.4 %). At 25 °F suction on a 95 °F day it gives 38.22 kW on R448A, against the 135 000 Btu/h (39.56 kW) printed. Modelled from the maker's published data — not verified by the manufacturer.
