Protection of equipment for water circulation systems


Inhibitor “B 9320” is dosed into the water circulation system constantly using a dosing pump. Dosing can be carried out directly from product drums or from working plastic containers. The joint supply of a corrosion inhibitor with bioscale inhibitors and dispersants is carried out to various places in the system (pump suction, cold water chamber, cooling tower bowl).


The dosage of the B 9320 inhibitor depends on the composition of the water. As a general recommendation, the working concentration of the inhibitor in the circulating water should be 20-50 g / cm3. At the initial application of the inhibitor, a shock dosage of about 30-50 ppm per volume of circulating water is recommended to form a protective film.
