Product Overview

Oxygen scavenger and preservative for boiler water treatment.

Detailed Description

Sodium Sulphite supplier in Oman - Global Chemicals LLC provides sodium sulfite for boiler oxygen scavenging, dechlorination, and food preservation in Muscat, Sohar, Salalah. Our sodium sulfite removes dissolved oxygen from feedwater, preventing corrosion in boiler systems. Sodium sulphite (Na₂SO₃) is a widely used oxygen scavenger, reducing agent, and preservative in Oman's water treatment, food processing, and photographic/industrial sectors. In boiler water treatment, sodium sulphite is the most cost-effective oxygen scavenger for low- and medium-pressure boilers (below 40 bar) — reacting with dissolved oxygen in feedwater to form sodium sulphate, preventing corrosive oxygen pitting of boiler steel and feedwater lines. Oman has a large installed base of steam boilers in food processing plants, laundries, hospitals, and industrial operations, all requiring consistent oxygen scavenging chemical supply. In food processing, sodium sulphite (E221) is used as a preservative and antioxidant in wines, dried fruits, fruit juices, and seafood. Global Chemicals LLC supplies sodium sulphite in technical grade (for boiler treatment) and food grade (E221) in 25kg bags. Dosage calculations for boiler treatment available from our technical team.
