PRODUCT NAME: RTW-120

TYPE: Zinc-Phosphonate Based Organic Corrosion & Scale Inhibitor

For Open Recirculating Cooling Water Systems

PRODUCT DESCRIPTION

RTW-120 is a high-performance corrosion and scale inhibitor formulated for open-loop recirculating cooling systems. It offers comprehensive protection against corrosion, scale formation, and fouling, particularly in low hardness, low alkalinity, and corrosive waters. The formulation incorporates zinc, organophosphonates, and polymeric dispersants for superior protection of ferrous and non-ferrous metal surfaces.

This environmentally responsible formulation is effective across a range of operating conditions and is especially beneficial where long-term system reliability and efficiency are critical.

KEY BENEFITS

Exceptional Corrosion Protection: Effective against pitting, galvanic, and general corrosion of ferrous metals.

Scale & Fouling Control: Polymer blend minimizes under-deposit corrosion and maximizes heat exchange efficiency.

Stability at High Temperatures: Performs reliably even at elevated skin temperatures.

Versatile Compatibility: Compatible with mixed-metal systems and yellow metals.

Single-Package Convenience: One product addresses corrosion, scaling, and fouling reducing handling and dosing complexity.

APPLICATIONS

RTW-120 is ideal for:

Open recirculating cooling towers

Low hardness and low alkalinity water systems

Industrial cooling systems in power plants, refineries, and process industries

FEEDING & DOSAGE

Start-up / Pre-treatment Dose: 50–100 ppm (for 2 weeks)

Maintenance Dose: 30–60 ppm in recirculating water

Maintain:

- Zinc concentration: >1 ppm
- System pH: Between 6.5 and 8.3
- Avoid use if Langelier Saturation Index (LSI) > 1

FEEDING METHOD:

Continuous dosing using a proportioning pump

May be fed as received or diluted

Use only PVC, polyethylene, or polypropylene dosing equipment

COMBINATION USE:

For enhanced scale inhibition, RTW-120 can be used with RTW-179 / RTW-170

STORAGE & SAFETY

Store in a cool, dry place, avoid direct sunlight, avoid contact with skin, eyes, and clothing. Use appropriate personal protective equipment.
