It prevents pitting and galvanic corrosion. It does not harm the nature as it does not contain chromate and phosphate. It is easy to use and economical. It is a clear-looking corrosion inhibitor consisting of a nitrite-borate-azole combination. Does not contain chromate and phosphate. It is used to prevent pitting and galvanic corrosion in closed circuit heating-cooling systems. Since it does not contain chromate and phosphate, it can condition closed-circuit heating-cooling systems without any risk of contamination. There is no harm in giving bluffs directly in water sources such as rivers and lakes. It is especially designed to control pitting and galvanic corrosion in systems containing several metals.
