Notes

Application Procedure

1. Water Analysis: Test makeup and circulating water for pH, conductivity, total hardness, calcium hardness, alkalinity, chloride, silica and other relevant parameters.

2. System Inspection: Evaluate existing corrosion, scaling, fouling and microbiological conditions.

3. Initial Dosing: Introduce the calculated amount of inhibitor into a suitable turbulent section of the circulating water system.

4. Continuous Dosing: Use a chemical metering pump to maintain the required treatment residual.

5. Water Chemistry Control: Maintain appropriate cycles of concentration through conductivity monitoring and blowdown.

6. Performance Monitoring: Monitor corrosion rates, deposit formation, inhibitor residual and heat exchanger performance.

7. Programme Adjustment: Adjust treatment based on operating data and changes in water quality.

9. Cooling Water Parameters to Monitor

The operating limits must be established for the specific cooling system.

10. Compatibility with Other Cooling Water Chemicals

RXSOL Cooling Water Corrosion and Deposit Inhibitor may be used as part of a comprehensive cooling water treatment programme incorporating:

• Oxidizing or non-oxidizing biocides

• Biodispersants

• Scale control polymers

• pH adjustment chemicals

• Cooling tower cleaning products

• Antifoaming agents

Compatibility should be confirmed before combining treatments.

Do not mix concentrated chemicals directly, particularly inhibitors and oxidizing biocides, unless compatibility has been verified.

Precautions

Corrosion Inhibition Mechanism

Corrosion in cooling water systems is commonly caused by dissolved oxygen, aggressive ions, unfavorable pH and electrochemical reactions on metal surfaces.

RXSOL Cooling Water Corrosion and Deposit Inhibitor is designed to reduce corrosion by supporting the formation and maintenance of protective conditions at compatible metal surfaces.

Depending on the selected formulation, corrosion protection may involve phosphate, phosphonate, zinc, molybdate, polymeric or other inhibitor technologies.

An appropriately selected treatment programme can help reduce corrosion of:

• Carbon steel pipelines

• Mild steel equipment

• Compatible heat exchanger components

• Cooling tower circulation equipment

• Other metals approved for the treatment chemistry

Copper and copper alloys may require a dedicated azole inhibitor. Aluminium and galvanized steel require additional compatibility assessment.

6. Scale and Deposit Control Mechanism

Cooling water contains dissolved calcium, magnesium, bicarbonate and other mineral ions.

As water evaporates in a cooling tower, dissolved mineral concentrations increase, creating conditions favorable for scale formation.

RXSOL Cooling Water Corrosion and Deposit Inhibitor is intended to control scale through mechanisms such as:

Threshold Inhibition: Helps delay mineral precipitation at concentrations below those required for stoichiometric sequestration.

Crystal Modification: Interferes with the formation and growth of certain scale crystals.

Dispersion: Helps maintain fine mineral particles in suspension, reducing their tendency to adhere to equipment surfaces.

Deposit Control: Supports cleaner heat-transfer surfaces when combined with suitable filtration, blowdown and water chemistry management.

Actual performance depends on the inhibitor formulation and the types of scale present.

Frequently Asked Questions

Q1. What is RXSOL Cooling Water Corrosion and Deposit Inhibitor used for?

It is intended to control corrosion, mineral scale and deposits in compatible industrial cooling water systems.

Q2. Can the product be used in cooling towers?

Yes, it is intended for selected open recirculating cooling tower applications.

Q3. Does the product prevent calcium carbonate scale?

A suitable inhibitor formulation can reduce calcium carbonate precipitation and deposition within its validated operating range.

Q4. Can it protect carbon steel and copper alloys?

Carbon steel corrosion inhibition is a principal application. Copper alloys may require additional corrosion inhibitor chemistry, such as azoles.

Q5. Can it be used in closed chilled water systems?

Not automatically. Closed chilled water systems generally require a different treatment strategy and may require a dedicated closed-loop corrosion inhibitor.

Q6. How frequently should the product be dosed?

Continuous dosing is commonly used in open recirculating systems, with the feed rate adjusted according to blowdown losses and monitored inhibitor residual.

Q7. Does this product replace biocides?

No. Corrosion and scale inhibitors do not necessarily provide microbiological control. A separate biocide programme may be required.
