Product Highlights
- Dual-function integrated formula that realizes simultaneous corrosion inhibition and scale prevention for power plant cooling water systems.
- Stable performance under harsh working conditions including high water hardness, high alkalinity and high concentration multiple of thermal power plants.
- Effectively protects carbon steel, copper and alloy heat exchangers, lowering equipment corrosion rate significantly.
- Suppresses the formation of calcium carbonate, calcium sulfate and silicate scales on heat transfer surfaces.
- Low required dosage cuts total water treatment cost; low-foam property will not interfere with system circulation.
Good compatibility with conventional circulating water biocides and other auxiliary water treatment chemicals.
