Which typical consequence may arise from using untreated water in cooling systems?

Using untreated water in cooling systems can lead to mineral buildup, which is a common consequence. Untreated water often contains various minerals and impurities that can precipitate and accumulate over time within the cooling system. This buildup can lead to scaling on heat exchange surfaces, which reduces the efficiency of heat transfer. As the scale forms, it acts as an insulating layer, making it more difficult for the system to effectively transfer heat. Consequently, this can cause the system to work harder to maintain desired temperatures, potentially leading to overheating and diminished performance.

In contrast, lower operating costs, improved thermal exchange, and extended equipment lifespan are generally associated with the use of properly treated water. Treated water minimizes the risks of corrosion, scaling, and fouling, thus optimizing system performance and prolonging the life of the equipment while ensuring operational efficiency.
