3-6 Connecting Aftercooler/Precooler Cooling Water (Optional)

Support both sides of the fitting when making the cooling water connections to prevent damage to the aftercooler coil. See Figure 9.

Connect 85°F water to the inlet closest to the exiting air side of the aftercooler coil. This will cool the process air about 100°F and raise the water-out temperature about 10°F. The table below lists available aftercooler models and their flow rates.
