The second, condensing coil,drenched by recirculated water spray, condenses by evaporation, transferring to the air 1,000 BTU for every pound of water evaporated. This done at low temperature, oo scale forms on coodenser tubes to clog air passage. Between the two coils is the MOilout", which purges the system of crankcase oil , and dirt, keeps'll always at full capacity. The "BalancedWet Bulb"control holds head pressure at the practical minimum. It automatically proportions the fresh air stream to tho condensing load with the full benefit of power-saving on cool days, providing full capacity for peak toads. Niagara Aeropass design results from over fifteen years' experience condensing by air. It is completely trustworthy for year 'round operation. Users say,"It saves half the difficulties and labor of running a refrigeration plant."
