SD 407 is an inhibitor used as an anti-scale and anti-corrosion water treatment program for cooling systems.
SD 407 is recommended for open circulating cooling and air conditioning systems. The product is most effective in the pH range from 7.5 to 9.0.
SD 407 is a concentrated liquid inhibitor based on phosphonates, polymers and dispersants.
SD 407 is an effective corrosion and scale inhibitor, acting by dispersion and complexation, washing away old, hardly soluble scale deposits, and promoting the formation of a protective film on the surface of equipment to prevent the appearance of new deposits.
SD 407 is resistant to temperature and hydrolytic decomposition.
SD 407 is dosed in concentrated form or diluted with soft water using a dosing pump in proportion to the amount of additional water. At the initial dosing stage, a dose is required to saturate and passivate the system with the product. If the system has been previously contaminated with biological deposits, biological cleaning of the system is mandatory before the initial dose of SD 407 inhibitor is administered.
Corrosion and scale inhibition is achieved by maintaining the system, depending on the water, evaporation rate and stability indices. Control is carried out in the salt transport system. Compatible with many non-oxidizing biocides used for biological control in cooling systems.
