What can occur if the pH level in water becomes too low in a cooling system?

When the pH level in water becomes too low in a cooling system, it leads to an increase in acidity, which can result in corrosion of metal components. A low pH environment causes the protective oxide layer on metals to break down, making the underlying material more susceptible to corrosion. This can accelerate the degradation of pipes, fittings, and other structures within the system, ultimately leading to leaks, structural failures, and costly repairs.

In cooling systems, proper pH levels are crucial not only to maintain water quality but also to ensure the longevity and functionality of the equipment. Regular monitoring and adjustment of pH levels can help prevent these damaging effects and ensure efficient operation. The other factors, such as fouling and scaling, are usually associated with high pH levels or the presence of specific contaminants, while overheating is generally a result of operational issues rather than water chemistry.
