BLOWDOWN VALVE PIPING
- The blowdown valve is fitted with a muffler for operation indoors. If the
installation requires, the muffler may be removed and the blowdown valve piped to the outside with a pipe
size the same as the blowdown valve outlet connection.
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.
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 15,
and Figure 2-6, page 15, 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
“Compressor Oil Cooler - Water-Cooled Heat Exchanger”, page 51 for more information on the water
system.
