[NOTES]
(1) The circle marks in the columns for corrosion or scale to develop.
(2) Corrosion has a tendency to occur when water temperature is high (104°F(40°C) or higher), and if metals with no protective
coating whatever are directly exposed to water, it is advisable to take eective measures against corrosion such as adding
a corrosion inhibitor or deaeration treatment.
(3) In a condenser water circuit that uses a closed cooling tower, the closed circuit circulating water and makeup water must
satisfy its water quality standards for the hot water system, and passing water and makeup water must satisfy those for the
circulation type cooling water system.
(4) Supply or makeup water should be tap water (clean water), industrial water, and underground water except for puried
water, neutral water and softened water or the like.
(5) The fteen items in the table above represent typical causes of corrosion and scale.
(6) Passing water may cause corrosion.
Do not use passing water.
