Chilled Water Treatment Corrosion Inhibitors
For Chilled Looped Systems, less then 45 degrees F, a nitrite/borate/silicate inhibitor (Closed Loop Chemical 338) is preferred. Sodium nitrite is a good metal passivator to minimize system corrosion. It is important to note, sodium nitrite is a food source for bacteria development, so it is important to monitor the system for bacteria growth. Since nitrite is a food source for bacteria growth, for Chilled Loop Systems systems over 45 degrees, a sodium molybdate chemical should be used to minimize system corrosion. Bacteria monitoring is recommended because of the higher water system temperatures.
Bacteria monitoring is recommended for all systems. Bacteria growth may lead to underdeposit corrosion and localized corrosion pits. This condition may lead to water leaks and early system failure. Bacteria that develops as slime may decrease the cooling system heat transfer efficiency and increase your energy costs.
Improper treatment may lead to excessive corrosion. In this case, excessive iron corrosion may also lead to iron build up on heat transfer areas and decrease the systems efficiency. This condition will decrease your heat transfer efficiency and may increase your energy costs.
