Ammonium Sulphite Solution – 40%

Ammonium Sulphite Solution – 40% – Premium Oxygen Scavenger for Industrial Applications

Ammonium Sulphite Solution – 40% is a widely used oxygen scavenger chemical designed for medium-strength corrosion control in industrial water systems. Its carefully maintained 40% concentration ensures predictable performance, especially in applications such as boiler feedwater treatment, chemical processing, and pulp and paper operations.

With its effective oxygen-removal properties, Ammonium Sulphite Solution – 40% helps extend the life of your equipment by preventing oxidation and corrosion inside pipes, heat exchangers, and tanks. It is trusted across Australia in sectors including power generation, oil refining, and manufacturing.

What Is Ammonium Sulphite Solution – 40%?

Ammonium Sulphite Solution – 40% is produced by reacting sulphur dioxide with aqueous ammonia. This process results in a pale yellow, water-soluble liquid containing 40% active ammonium sulphite by weight. Though chemically different, some industries may refer to it as ammonium bisulfite (US spelling) in the United States.

The 40% strength formulation provides a reliable balance between stability and reactivity, making it a safer alternative to stronger reductive agents for oxygen control.

Key Industrial Applications

This solution is ideal for:

• Boiler feedwater treatment to eliminate dissolved oxygen before it causes scale and internal corrosion.
• Use as a corrosion inhibitor in cooling towers, pipework, and closed-loop systems.
• Bleaching and lignin breakdown in the pulp and paper industry.

The debate between sulphite vs bisulphite is often resolved in favour of sulphite when lower reactivity and thermal stability are key priorities. That’s why Ammonium Sulphite Solution – 40% is an ideal fit for moderate-risk systems needing controlled protection.
