BLOWDOWN VALVE PIPING

- The blowdown valve is piped back into the airend between the inlet valve

and air filter.

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.

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 19,
and Figure 2-6, page 19, 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 54 for more information on the water
system.

Figure 2-7 – SERIES PIPING

SERIES PIPING

(Figure 2-7, page 20) - Water flow must be through aftercooler first for effective cooling

of discharge air and is so piped on the standard water-cooled unit.
