Product Highlights
Integrated dual-function formula tailor-made for petrochemical cooling water, achieving simultaneous corrosion inhibition and scale control.
Stable performance under harsh petrochemical working conditions with high hardness, high alkalinity and high concentration multiple.
Restrains calcium carbonate, calcium sulfate and silicate scaling, and forms anti-corrosion protective films on carbon steel, copper and alloy heat exchangers.
Low-foam liquid formulation prevents cooling tower foam overflow and will not hinder system circulation and heat transfer efficiency.
Good compatibility with oxidizing & non-oxidizing biocides and other petrochemical water treatment chemicals without negative reactions.
Low effective dosage cuts chemical operating costs, adapts well to fluctuating raw water quality of refineries and chemical plants.

Performance:
This product, developed through extensive laboratory testing and field application improvements, is a high-efficiency scale and corrosion inhibitor. When used in recirculating cooling water systems, it provides excellent corrosion inhibition for metals such as carbon steel, stainless steel, and copper. It strongly inhibits scale deposition and has outstanding dispersing properties for foulants.
Application:
As a scale and corrosion inhibitor, it can be widely used in open recirculating cooling water systems in petroleum refineries, deep petroleum processing plants, and deep natural gas processing plants.
Usage Method:
Dosage varies depending on the water quality indicators and process parameters of the application system. Generally, based on the makeup water volume, the dosage concentration should be controlled at around 20-50 mg/L. Suitable for pH range 7.0 – 9.5.
Packaging, Storage & Transportation:
Packed in 25 kg, 200 kg, or 1000 kg plastic drums. Store in a cool, dry place. Shelf life is twelve months. Handle with care during transportation to prevent impact.
