KeepRite's KEZA009H8, a one-fan air-cooled scroll condensing unit for a walk-in cooler, as this model runs it: the Copeland ZB08KAE 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 100 W EC fan that draws 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, 9 780 Btu/h): 823 cfm, air the printed fan could move through that coil. That same condenser holds all 216 cells the manual prints for this unit on R404A, R407A, R448A and R407C within −4.4 to +3.8 % (RMS 1.7 %). At 25 °F suction on a 95 °F day it gives 2.83 kW on R448A, against the 9 840 Btu/h (2.88 kW) printed. Modelled from the maker's published data — not verified by the manufacturer.
