The main aim of a cooling system is to remove heat from a piece of equipment or process. This result comes from using cold water, which gets heated as a result of the process. The water can then be cooled, reused, or discharged into a receiving body.NCH Asia Pacific’s cooling water treatment is trusted and available to industrial, infrastructure, and hospitality industries. Water treatment solutions from NCH Chem-Aqua protects your cooling water systems from deposits, corrosion and microbiological growth. We’ve worked hard to ensure that our solutions save water, maintenance and energy costs as low as possible, while maximizing the lifespan of your cooling water system.

Preventing corrosion is very important if you want to avoid the premature deterioration of your cooling tower. Deposits of minerals and biological sources like microbes can cause metal corrosion. The efficiency of the equipment will, over time, deteriorate, and the system can fail if corrosion is not prevented.

Scale and deposits
Scale deposits will form an insulating barrier on the heat exchange surfaces, reducing the efficiency of the heat transfer in your cooling system. These deposits will also cause problems such as under deposit corrosion within the system.

Microbiological growth
Microorganisms can build up in cooling systems and lead to the formation of biofilms. These biofilms cause a number of problems, including slime and fouling. Fouling affects equipment performance and promotes metal corrosion. In some cases bacterial growth can lead to health risks.

The growth of the harmful Legionella bacteria is frequent in cooling towers as they provide the ideal conditions for it to survive and multiply. Legionella can cause serious health risks, such as respiratory infections. It is crucial to prevent legionella in facilities where many people can be affected, such as hospitals, hotels, and schools.

Effective water treatment is a critical part of the preventive maintenance program for a water system. System repairs or replacements are expensive and can be avoided with regular maintenance.
