Product Name: Cooling Water Corrosion and Deposit Inhibitor Brand: RXSOL Product Category: Industrial Water Treatment Chemicals Application: Cooling Towers, Industrial Cooling Water Systems, Heat Exchangers and Recirculating Water Circuits
RXSOL Cooling Water Corrosion and Deposit Inhibitor is a specially formulated liquid water treatment chemical designed to provide combined corrosion inhibition, scale control and deposit management in industrial cooling water systems.
Cooling water systems are continuously exposed to dissolved minerals, oxygen, suspended solids and varying operating temperatures. These conditions can lead to corrosion, mineral scale formation and deposit accumulation on heat-transfer surfaces, pipelines and equipment.
RXSOL Cooling Water Corrosion and Deposit Inhibitor is designed to address these problems through a balanced treatment programme that helps protect compatible metallic surfaces while controlling the precipitation and accumulation of scale-forming minerals.
The product is suitable for use in open recirculating cooling towers and compatible industrial cooling water circuits, subject to water quality, system metallurgy and operating conditions.
Cooling Towers: Used in open recirculating cooling water systems to control corrosion and mineral scale.
Heat Exchangers: Helps reduce mineral deposits on compatible heat-transfer surfaces.
Industrial Cooling Circuits: Supports corrosion and deposit control in process cooling systems.
Condensers: Helps minimize scaling and corrosion in compatible cooling water condensers.
Power Plants: Used as part of cooling water treatment programmes for suitable power generation cooling circuits.
Petrochemical and Refinery Cooling Systems: Supports corrosion and scale management in industrial cooling water networks.
HVAC Cooling Systems: Suitable for selected central air-conditioning cooling tower applications.
Manufacturing Facilities: Used in cooling water circuits serving chemical plants, steel processing, plastics, textile and other industrial operations.
The required dosage depends on circulating water quality, hardness, alkalinity, chloride concentration, operating pH, cycles of concentration and system metallurgy.

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.
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.
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.

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.
