Reference
• The "O" mark for corrosion and scale means that there is
possibility of occurrence.
• When the water temperature is 40 °C (104 °F) or above or when
uncoated iron is exposed to the water, it can result in corrosion.
Therefore adding anti-corrosion agent or removing the air can be
very effective.
• In case of using the closed type cooling tower, the cooling water
and supplementing water must satisfy the water quality criteria
of closed type system in the table.
• Supplementing water and supplied water must be supplied with
tap water, industrial water and underground water excluding
filtered water, neutral water, soft water etc.
• 15 items in the table are general causes of corrosion and scale.

- • Use 2 belts of at least 8 m (26.2 ft) long.
-
• Place extra cloth or boards in the locations where the casing
-
comes in contact with the sling to prevent damage.
