MIL-HDBK-1003/7
The temperature of auxiliary cooling water from the heat exchangers should
be maintained constant by use of an automatic temperature control system which regulates
a control valve to bypass auxiliary cooling water around the cooling water heat
exchangers.
The auxiliary cooling water in the system is treated initially upon filling
with chemical additives to prevent corrosion throughout the system. Chemical
concentration of water contained in the system is maintained during plant operation by
periodic injection of chemicals. This is accomplished by means of a pot feeder located
on the discharge of the auxiliary cooling water pumps.
