WATER QUALITY
It is the responsibility of the Owner or
End User to have the cooling water
analyzed and chemically treated as often
as is necessary so that it conforms to the
limits shown in Table 1. The water
quality in the chilled/hot water and the
cooling water circuits should not exceed
the following limits:
Note:
1.
Items shown in the Trend column: An
“O” mark indicates the potential issue should this line item go
out of acceptable range.
2.
When water temperature rises above 104°F
(40°C)
, the tendency for corrosion rises remarkably. As
such, there may arise a need for additional corrosion protection measures such as buffers and
inhibitors.
3.
For closed-loop cooling towers, use the Hot Water column data in the Circulating Water chart instead
of the Cooling Water column data. For make-up water, use the Chilled Water column data instead of
the Cooling Water column data.
