Unit size 21 corresponds to a nominal airflow of roughly 10,000 CFM in Carrier's 39M range. The cabinet is double-wall galvanized construction with hinged, latched access doors on each section. Per the unit nameplate, the air handler is arranged (A) mixing box, (B) flat filter section with (6) 20x25 pre-filters and (6) 20x25 main filters, (C) chilled water and hot water coil section with plenum, (D) blow-thru supply fan section, and (E) discharge plenum. The chilled water coil (28MCV038DAA065BRNC) and hot water coil (28MHV238FAA065BRNC) are each rated 300 PSIG maximum operating pressure at 200 F. The supply fan section uses two 7.5 HP, 1800 RPM motors on 460V/3-phase/60 Hz power, 9.7/12.1/20 FLA/MCA/MOCP each, 23.0 maximum continuous amps. The unit is photographed as installed, with factory-supplied ABB HVAC variable frequency drives and unit-mounted service switches, Eaton heavy duty safety switches (60 A and 100 A, 600 V) for unit and ancillary power, and Belimo-style actuated outside air and mixing dampers.
