Maintain stable cooling performance and significantly reduce maintenance costs.

By reducing dissolved Ca²⁺ (calcium), Mg²⁺ (magnesium), SiO₂ (silicon dioxide), and others in the cooling water at the (-) electrode through electrolysis, and precipitating them in the form of CaO (calcium oxide), it automatically discharges outside the circulation system, preventing the formation of scale inside and outside the cooling device's piping. The water with altered electrolyte structure replenishes the substances causing scale that were removed through the electrolysis reaction while circulating, maintaining a state of equilibrium. Therefore, it separates the substances causing scale from the existing scale attached to the inside of the cooling tower, circulation piping, heat exchangers, etc., and discharges them from the aqueous system through electrolysis. This can be applied to all locations using circulating water from cooling towers, allowing for the separation and discharge of scale within the circulating water and even the invisible scale inside the piping. It also prevents the proliferation of Legionella bacteria and aerobic microorganisms that occur during the summer through electrolysis. It can be applied to various cooling devices such as heat exchangers (evaporators, condensers) necessary for freezing during the production process of seafood processing/storage and food/beverage processing/storage, as well as in molding processes, die casting, compressors, pressing equipment, and indirect heaters.

Applications/Examples of results

It can be applied not only in the manufacturing sector but also in all places that require cooling circulating water, such as department stores, large shopping centers, general hospitals, hotels, condominiums, government buildings, and schools. It can be used in all locations that utilize circulating water from cooling towers, allowing for the separation and discharge of scale within the circulating water and even the invisible scale inside the circulating water pipes. It prevents the proliferation of Legionella bacteria and aerobic microorganisms that occur during the summer through electrolysis. It can be applied to various cooling devices, such as heat exchangers (evaporators, condensers) required during the production process of refrigeration units for seafood processing/storage and food and beverage processing/storage, as well as in molding processes, die casting, compressors, pressing equipment, and indirect heaters.
