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.
