WFS 101545 Operations Manual
The system provides two (2) separate cooling circuits. One is specifically for cooling the dicing
or sawing process. The other provides cooling water to the spindle or drive motors. Used
process water is cooled by refrigeration, filtered and deionized. Used spindle cooling water is
cooled by refrigeration in a separate circulating loop.
In addition to the built-in filtering and refrigeration capabilities, the WFS has provisions to accept three
(3) customer supplied 2.5 cubic foot (70.8 liter) resin tanks for additional filtering and/ or deionization.
The system has three water circulating loops:
Process Loop
Spindle Loop
Internal Recirculating Loop.
Additionally, a separate Lift Station pump is provided to return process water back to the WFS.
a.
Process Loop
The Process Loop recirculates temperature controlled, filtered and deionized water for
dicing and grinding. It is rated to provide 15 GPM at 45 PSI.
b.
Spindle Loop
This loop recirculates water cooled by refrigeration for the dicing spindle motors.
