RXSOL Triazole-Based Corrosion Inhibitor

For Closed and Open Cooling Water Systems

Brand: RXSOL
Product Category: Industrial Water Treatment Chemicals
Chemical Base: Tolyltriazole (TTA) / Benzotriazole (BTA)
Application: Cooling Towers, Chilled Water Systems, HVAC Circuits, Heat Exchangers and Industrial Cooling Water Networks

Supplementary corrosion inhibitor - open or closed cooling systems

RXSOL-40-4028 is an innovative, supplementary corrosion inhibitor developed specifically for use in open or closed cooling systems. 

Application

In particular, RXSOL-40-4028 creates an insoluble polymeric surface complex on copper and its alloys, and also reacts with copper in solution. RXSOL-40-4028 also works synergistically with other inhibitors to effectively control the corrosion of steel and aluminium in the system.

Control and dosage of RXSOL-40-4028 - The dosage of RXSOL-40-4028 required varies widely with different applications.

Dose

Recommended Dosing

These values refer to active triazole concentration in circulating water, not the amount of commercial product.

Application

Indicative Active Triazole Target

Open cooling tower – initial treatment

10–20 ppm

Open cooling tower – maintenance

1–3 ppm

Closed cooling water system

2–10 ppm, according to metallurgy and program

Aggressive water conditions

Determine from corrosion testing

Typical open-tower passivation and maintenance ranges are supported by published cooling-water treatment guidance. Closed-loop requirements can vary significantly, particularly with mixed metallurgy.

 

For a product containing 19.8% active triazole, a theoretical 5 ppm active treatment in 100,000 litres requires approximately 2.53 kg of product, excluding consumption and system losses.

Typical initial dosage for an untreated system is 8 liters of product per 1000 liters of water.

Remarks / Precaution

Key Advantages

  • Excellent corrosion inhibition for copper and copper alloys.

  • Helps minimize copper corrosion and metal-ion release.

  • Suitable for open and closed cooling water systems.

  • Compatible with many phosphate, phosphonate, molybdate and polymer-based treatment programs, subject to testing.

  • Helps protect copper tubes in condensers and heat exchangers.

  • Available as a concentrated liquid formulation.

  • Can be formulated as a nitrite-free product.

  • Suitable for integration into multi-metal corrosion inhibitor programs.

Important: Triazoles primarily protect copper and copper alloys. For carbon steel, cast iron and aluminium, additional corrosion inhibitors are generally necessary.

Note

Product Description

RXSOL Triazole-Based Corrosion Inhibitor is a specialized corrosion-control treatment designed to protect copper, brass, bronze and copper-alloy components in industrial cooling water systems.

The product utilizes triazole chemistry to form a protective film on copper-containing surfaces, minimizing metal dissolution, corrosion and copper-ion release.

 

It can be incorporated into both open recirculating and closed-loop cooling water treatment programs.

RXSOL-40-4028-025 is water treatment chemicals and cleassified as a cooling water treatment chemicals. RXSOL-40-4028-025 principally works as corrosion inhibitors in cooling water treatment chemicals.

RXSOL-40-4028-025 most commonly used as a corrosion inhibitor for open closed cooling water systems.
