– AFTERCOOLER APPROXIMATE WATER FLOW
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 enclosure flange on
the end of the unit opposite the control box.
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 17,
and
, page18, 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.
