What is cooling tower scale? 【Basic Knowledge】
Does it become concentrated enough to evaporate water? An explanation of the nature of cooling tower scale.
■What is scale? Cooling towers can develop scale over long periods of use. Scale is the accumulation of "minerals" such as calcium and magnesium. Specifically, it includes calcium, magnesium, silica, and iron. ■Why does scale form? Cooling towers operate by evaporating a portion of the water, using the heat of vaporization to cool the remaining water. Only water molecules evaporate, leaving the minerals behind, which increases the concentration of minerals in the water as the cycle repeats. This "evaporation concentration" causes the minerals to become insoluble, resulting in the crystallization that forms scale. ■Where and what kind of damage occurs? Scale can attach not only inside the cooling tower but also to heat exchangers, copper pipes, and plumbing. If not detected early, the damage could become significant. Scale issues can severely reduce the cooling tower's efficiency and corrode metals. ■What are the key points for countermeasures? As long as cooling towers are in use, scale removal is essential. Regular water quality management and periodic inspections and cleaning are crucial to prevent efficiency loss and corrosion. Please feel free to consult us first.
