Cooling towers are heat-transfer units, used to remove heat from any water-cooled system. The cooled water is then re-circulated back into the system. Since the process water is re-circulated, the mineral concentration increases as a result of the evaporation.
Performance of this unit is critical for efficient and economical operation. The heat transfer surfaces must be kept as clean as possible to assure maximum heat transfer. As the mineral content in the cooling water increases, the potential for scaling and corrosion increases, threatening efficient operation of the heat exchanger.
Corrosion can be minimized by the addition of a corrosion inhibitor. Which is a chemical compound that, when added in small concentration stops or slows down corrosion of metals and alloys. Inhibitors are chemicals that react with a metallic surface, or the environment this surface is exposed to, giving the surface a certain level of protection.
CoastalZinc® Zinc chloride as an effective corrosion inhibitor with good properties that is more environmentally friendly than the current common phosphonate corrosion inhibitors, particularly for use in cooling water treatment chemicals. The increasing use of zinc chloride from industries such as power, steel, mining and metallurgy, petrochemicals, oil & gas, and food & beverages is driving the growth of the market for corrosion inhibitors. In these industries, the corrosion inhibitors are injected into water cooling systems in specified doses to prevent scaling, corrosion, and growth of bacteria in water.
CoastalZinc Group has mastered the research and manufacturing technology of zinc chloride, the core product of water treatment application, and solved many problems and market pain points encountered in the process of water treatment, so as to provide high-quality products and services for industrial customers.
