8457 | Nalco

In the demanding world of industrial water treatment, the battle against corrosion, scaling, and fouling is constant. Among the arsenal of specialty chemicals designed to protect critical assets, stands out as a benchmark product. Manufactured by Ecolab’s Nalco Water division, Nalco 8457 is a high-performance liquid corrosion inhibitor specifically engineered for open recirculating cooling water systems.

Before implementing Nalco 8457, always perform a comprehensive water analysis and consult with an Ecolab/Nalco representative or a qualified water treatment professional. Proper application, monitoring, and safety protocols will ensure that your cooling water system delivers maximum reliability at minimum total cost of ownership. Nalco 8457

Nalco 8457 is a multi-metal corrosion inhibitor formulated to protect yellow metals (copper and its alloys), steel, and other ferrous components commonly found in cooling towers, heat exchangers, and chiller systems. Unlike traditional phosphate-only programs, Nalco 8457 utilizes a synergistic blend of azoles, organic phosphonates, and dispersant polymers. In the demanding world of industrial water treatment,

Specifically formulated for steam-generating systems to maintain water quality and prevent acid-driven metal degradation. PEW systems) Safety and Handling

Dissolved oxygen is the primary driver of corrosion in boiler systems. Nalco 8457 contains an oxygen scavenger—typically sulfite-based (common in formulations for low-pressure boilers)—which chemically reacts with dissolved oxygen to render it inert. By removing the oxygen, the chemical prevents the electrochemical reaction known as rusting or pitting.
