b.
FILTRATION
The WFS uses Pall or FSI X100 filters that use disposable filter cartridges for filtration of the process
water. The filters are arranged in two cascading sets, one set of three filters for the Internal
Recirculating Loop and one set of two filters
3
for the Process Loop. We recommend having
increasingly finer filtration as the water cascades through the filters.
i.
Filter Housings
The filter housings are manufactured from talc filled polypropylene and rated for 100 psi
maximum pressure and 110
o
F degrees maximum temperature.
ii.
Filter Elements
Each filter housing is designed to hold three cartridge type filter elements. The housings
accept filter cartridges of various composition and filtration rating. The customer must
determine the type of filter element to best satisfy their requirements.
iii.
Gauges
Each filter housing has a pressure gauge mounted directly on top. WFS. These gauges
provide indication of the filter condition. The filter elements should be changed when the
gages indicate a pressure increase in excess of 20 PSI.
NOTE: For detailed information concerning the filter housing see the link to manufacturer’s design data in
the appendix.
c.
CHILLER
WFS 1545 chiller unit is specifically designed and built for use with processing semiconductors.
However, it can be applied to any process that requires refrigerated and filtered water. The chiller
3
F6 Variant uses 3 filters on the process side
