Ammonium Bisulphite - 70%
Highest concentration (70% w/w) Ammonium Bisulphite aqueous solution. Engineered for maximum efficiency as an industrial reducing agent and dissolved oxygen scavenger.
Ammonium Bisulphite - 65%
Industrial grade 65% concentration Ammonium Bisulphite solution. Widely favored for oilfield deoxygenation, dye manufacturing, and wastewater dechlorination.
Ammonium Bisulphite - 60%
Standard 60% active Ammonium Bisulphite solution. Highly stable, reliable, and cost-effective for general industrial reducing and water processing needs.
Ammonium Bisulphite Food Grade
Ultra-pure food-grade Ammonium Bisulphite compliant with food safety regulations. Critical additive for caramel color production, sugar processing, and preservation.
Ammonium Sulphite Solution - 40%
High-purity neutral-alkaline Ammonium Sulphite 40% solution. Key formulation for photographic developers, pulp pulping, flue gas desulphurization, and chemical synthesis.
Oxygen Scavenger
Engineered liquid Oxygen Scavenger for complete elimination of dissolved oxygen in boiler feed water, oilfield waterflood lines, and deep-well injection fluids.
