Corrosion Scale Inhibitor Boiler Treatment is a high-performance liquid treatment, specially engineered with phosphate polymers for application in steam boilers.
Formulated for systems utilizing softened make-up water, AquaShield B64 effectively disperses iron and phosphate sludge, ensuring clean and efficient boiler operation.
The advanced polymer blend promotes the transport of calcium, magnesium, iron, phosphate, and silica through the boiler system, preventing the formation of stubborn deposits.
By minimizing scale and sludge buildup, AquaShield B64 helps extend steam production cycles, enhances heat transfer efficiency, and reduces the risk of tube overheating and associated maintenance downtime
Corrosion Inhibitor OPEN Cooling System scientifically formulated to keep clean open recirculating systems and also prevent from scale formation . Chemically Corrosion Inhibitor OPEN Cooling System will disperse scale and corrosive products, silt etc and can be used as an anti-foulant along with other treatments.
Excellent scale inhibition for a variety of applications including cooling circuits, boilers and RO units.
It is widely used in Boilers, cooling water and membranes
Dosage (ppm) = (Feedwater Hardness × F) + (Feedwater Iron × 20)
Select Factor F based on boiler pressure:
Use F = 23 for boilers up to 30 bar.
Most industrial and utility boilers globally operate between 10–40 bar (low to medium pressure steam production).
F = 23 works well for boilers using softened feedwater, which is very common internationally.
Even for pressures slightly above 35 bar (up to 45 bar), using F = 24 still keeps treatment safe and effective without under- or overdosing.
Manage Phosphate reserve after dosing the product as per below:
| Boiler Pressure | Phosphate Reserve |
|---|---|
| 0–20 bar | 30–70 ppm |
| 21–40 bar | 20–50 ppm |
| 41–60 bar | 20–40 ppm |
| 61–70 bar | 15–30 ppm |
Maximum pressure limit for this product is 60 bar.

Simpler Direction for use
RXSOL Boiler Corrosion Scale Treatment should be dosed continuously to ensure effective boiler protection. It may be applied neat or diluted with soft water or cooled condensate and must be injected using a dedicated dosing system. The product must not be mixed in concentrated form with oxygen scavengers or condensate corrosion inhibitors.
The treatment is normally used together with RXSOL Alkalinity Control as part of a conventional alkaline phosphate programme for high-pressure boilers, where separate control of phosphate and alkalinity is required.
Dosage depends on feed-water quality, boiler design and steam load, and is controlled by maintaining the required phosphate (PO₄) level in boiler water using a standard test kit. As a general guide, dosing at 0.25 litres per tonne typically increases the phosphate reserve by approximately 10 mg/L, depending on water quality.
Frequently Asked Questions about Boiler treatment
Answer:
A corrosion scale inhibitor is a chemical solution designed to prevent rust, corrosion, and scale formation inside boiler systems. It protects metal surfaces from degradation and ensures smooth heat transfer, ultimately extending the lifespan of the boiler and reducing energy costs and maintenance downtime.
Answer:
Choosing the right inhibitor depends on:
Boiler pressure and temperature
Feedwater quality (e.g., hardness, pH, oxygen content)
Type of scaling or corrosion (e.g., calcium carbonate vs. oxygen pitting)
Look for inhibitors that are multi-functional, offering both scale and corrosion protection, and ensure they’re compatible with your boiler material (carbon steel, copper alloys, etc.).
Answer:
The frequency of dosing depends on your boiler’s operating conditions, feedwater quality, and the type of inhibitor used. Typically, dosing is done continuously through a dosing pump or daily during boiler operation. Regular water testing and monitoring (pH, conductivity, hardness) is essential to maintain the correct inhibitor levels and ensure optimal protection against corrosion and scale.
