The heat exchanger system is designed to operate with water inlet temperatures from 60° F to 90° F (16°
C to 32° C) and a water outlet temperature not to exceed 110° F (43° C). If water cooler than 60° F is
used, high water outlet temperatures (over 110° F, 43° C) will be experienced along with shortened heat
exchanger life caused by tube fouling and corrosion. If water warmer than 90° F (32° C) is used, higher
compressor oil inlet temperatures and high water usage will result.
Most water systems will require control of impurities: filtration, softening or other treatment. See Section
5, "Compressor Oil Cooler - Water-Cooled Heat Exchanger" for more information on the water system.

SERIES PIPING (Figure 2-7) - Water flow must be through aftercooler first for effective cooling of
discharge air and is so piped on the standard water-cooled unit.
