Oxygen Scavenger Boiler Oxy Control

RXSOL-42-1524-030 is a easy to handle liquid solution that can be used as both a powerful oxygen scavenger for low and medium pressure steam boilers and also a neutraliser for removing chlorine and other biocides to protect sensitive systems such as RO plants or prior to discharge to the environment. RXSOL-42-1524-030 is intended for applications such as the food industry where formulations including heavy metal catalysts cannot be used.

Application and Dosage

As Boiler Water Oxygen Scavenger

Rapid reaction with oxygen ensures efficient protection of feedlines and boilers from corrosion. RXSOL-42-1524-030 is intended for those applications such as the food industry where heavy metal catalysts cannot be used. RXSOL-42-1524-030 reacts with oxygen to form bi-products which have no adverse effect on boiler integrity. One of these bi-products enhances protection against caustic embrittlement.

RXSOL-42-1524-030 should be dosed at the rate of 18ml/m3 for every ppm of dissolved oxygen. A reserve of approximately 50ppm of sulphite should be maintained in the boiler water.

As Biocide Neutralizer

RXSOL-42-1524-030 is an effective neutraliser of halogens, particularly chlorine, and a wide range of other biocides. It can be used to neutralise excess chlorine following disinfection of water systems, including cooling water systems and the feed to RO systems. RXSOL-42-1524-030 can also be used to prepare waste streams for disposal to treatment services, including public utility services, by conditioning residual biocide including, but not limited to, C/MIT, DBNPA and THPS.

RXSOL-42-1524-030 is dosed at the rate of 7 – 10 ml/m3 per mg/l of free chlorine

Features and Benefits

• Reacts with oxygen to produce compounds that do not harm boiler integrity. One of these compounds further improves protection against caustic embrittlement.
• Suitable for loq and medium pressure boilers
• Catalysed product to ensure efficient protection from corrosion

How Oxygen Scavengers Increase Boiler Efficiency

1. Prevents Corrosion of Internal Components

Dissolved oxygen causes pitting corrosion on boiler tubes and metal surfaces. This leads to:

• Oxygen scavengers eliminate O₂ before it can damage metal, maintaining smooth heat transfer surfaces.

2. Reduces Blowdown Frequency

Corroded systems need frequent blowdowns to remove scale and sludge.

• With corrosion minimized, the system stays cleaner, reducing blowdown frequency — saving water, energy, and chemical treatment costs.

3. Improves Heat Transfer Efficiency

Corrosion creates deposits and scale, which:

• Oxygen-free systems stay deposit-free, ensuring optimal thermal conductivity and lower fuel consumption.

4. Extends Equipment Life

• Corrosion damages critical parts like:
  Using scavengers increases the lifespan of boiler systems, reducing capital expenditure and maintenance.

5. Protects the Entire Steam Loop

Not just the boiler, but the entire steam-condensate loop benefits:

• Oxygen scavengers continue to work in condensate lines
• Protects downstream equipment and piping
