WATER PIPING (Water-Cooled Heat Exchanger Models Only)
- On machines equipped with water-
cooled heat exchangers, the water inlet and outlet connections are located in the unit base flange on the
left side of the unit.
WARNING
It is mandatory that any water cooled unit be installed in a shelter heated to
temperatures above freezing (32
°
F., 0
°
C).
The water source should be capable of supplying up to the maximum flow shown in Figure 2-5, page 14,
and Figure 2-6, page 14, at a minimum pressure of 40 psig (2.8 bar); maximum allowable water pressure
is 150 psig (10.3 bar). The water flow rates shown are approximate and a guide to sizing piping, cooling
tower and other water system equipment.
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.
