WATER TREATMENT
Proper water treatment is a specialized industry . We recommend
consulting an expert in this field to analyze the water for
compliance with the water quality parameters listed in Table 1
below . The material used in the ClimaCool chiller exposed to the
water are type 316 stainless steel, pure copper, and carbon steel .
Other materials may exist external to the ClimaCool chiller . It is
the users responsibility to ensure these materials are compatible
with the treated water . Failure to provide proper water quality
will void the ClimaCool module’s warranty . NOTE: For warranty,
proof of monthly water testing results showing compliance to
Table 1 Water Quality Parameters is required . Failure to provide
proper water quality will void the ClimaCool module’s warranty .
It is further recommended to seek an experts advice to specify
the appropriate water treatment required . Typical additives to
hydronic systems include rust inhibitors, scaling preventative,
antimicrobial growth agents, and algae preventatives . Anti-freeze
solutions may also be used to lower the freezing point .
Heavily-Contaminated Water
In such instances whereby the particulates in the water are
excessive it is recommended to install an intermediate plate &
frame heat exchanger to isolate the ClimaCool chiller from the
building water system .
Other Considerations
The following considerations are listed to help achieve system
longevity .
Cooling Tower
The cooling tower should be located away from sources of
external contaminates such as trees, dust, or grass cuttings . Insect
infiltration can be reduced by eliminating lights near the tower .
A periodic visual inspection of the tower system should be made
and contaminates removed as required .
