Oxygen Scavenger for Pharmaceutical‑Grade Boiler Feedwater
Product Overview
Our oxygen scavenger for pharmaceutical grade boiler feedwater is a high‑purity, water‑soluble additive designed to protect steam‑generating systems used in drug manufacturing, sterile processing, and biotech facilities. By chemically binding dissolved oxygen, it prevents corrosion, scale formation, and microbial growth that could compromise product integrity or equipment lifespan. Formulated to meet the strict limits of USP pharmaceutical and EP, it delivers consistent performance even under high‑temperature, high‑pressure conditions.
Available in granular and liquid formats, the product can be dosed directly into the feedwater loop or introduced via a metered injection system, offering flexibility for both new installations and retrofit projects.
How It Works
The scavenger contains a proprietary blend of sulfite‑based chemistry and chelating agents. When introduced into boiler feedwater, the sulfite reacts with dissolved oxygen according to the equation:
2 SO₃²⁻ + O₂ → 2 SO₄²⁻
This reaction removes oxygen faster than traditional sodium sulfite alone, while the chelators bind trace metals that could otherwise catalyze corrosion. The result is a stable, low‑conductivity water environment that meets the rigorous purity standards required for pharmaceutical steam generation.

Safety data sheets (SDS) are provided with every shipment, and the product is classified as non‑flammable, non‑corrosive to metal, and safe for handling with standard PPE (gloves, goggles).
Frequently Asked Questions
What is the minimum order quantity (MOQ)?
MOQ is 500 kg for granular bulk, or 250 L for liquid concentrate. Smaller batches can be arranged through our custom‑mix service, subject to a setup fee.
Can the scavenger be tailored to my system’s dosing strategy?
Yes. We offer dosage‑rate optimisation, particle‑size adjustment for granular products, and concentration tweaks for liquid formulations to match specific feedwater flow rates and oxygen load profiles.
What is the typical lead time?
Standard production runs ship within 15–45 days after order confirmation, depending on volume and any required customisation.
Is there a warranty or performance guarantee?
We provide a 12‑month performance warranty covering oxygen removal efficiency when used according to the supplied dosing guidelines. Replacement or credit is issued if specifications are not met.
