25Ltr Nalfleet Cooltreat Al Organic Corrosion Inhibitor

NALFLEET™ Cooltreat AL™ is a premium, organic liquid corrosion inhibitor designed for closed engine cooling water systems. Unlike traditional inhibitors, it forms a thin, durable protective layer on metal surfaces, preventing corrosion while maintaining excellent heat transfer efficiency.

This innovative solution is based on aliphatic acid technology, making it non-depleting and requiring less frequent testing. Its environmentally friendly, biodegradable formulation ensures compliance with modern marine regulations.

Ideal for protecting materials such as aluminium, steel, and brass, NALFLEET™ Cooltreat AL™ is perfect for use in:
Diesel Engines
Compressors
Central Heating Systems
Auxiliary Machinery Cooling Systems

Key Features:

• Effective Corrosion Protection – Guards against cavitation, erosion, and scaling.
• Superior Heat Transfer – Prevents insulating layer build-up on heat transfer surfaces.
• Environmentally Friendly – Fully organic, biodegradable, and low toxicity.
• Stable and Long-Lasting – Non-depleting formula reduces the need for frequent testing.
• Aluminium Safe – Compatible with aluminium components.
• Compatible with Glycols – Ensures effective frost protection when mixed with glycol solutions.

Benefits:

• Reduced Maintenance – Extended system life with minimal upkeep.
• Improved Efficiency – Superior heat transfer improves performance.
• Versatile Use – Suitable for various marine and industrial applications.
• Environmentally Responsible – Eco-friendly formulation that meets modern marine standards.
• Tested and Approved – Approved by major engine manufacturers.

Directions for Use:

1. System Preparation:

For new systems, clean the system with UNITOR™ Commissioning Cleaner before applying Cooltreat AL.For contaminated systems, degrease using UNITOR™ Seaclean Plus followed by descaling with UNITOR™ Descalex.

2. Dosing Method:

Add 60 litres of Cooltreat AL™ per 1,000 litres of untreated distilled water (6% concentration).
For systems with aluminium components, ensure Cooltreat AL is used rather than traditional inhibitors.

3. Maintenance and Testing:

Regularly test the system using the Spectrapak Test Kit to ensure optimal inhibitor levels.
Maintain pH levels between 7.0 and 9.0 and ensure chloride levels are below 50 ppm.

4. Make-Up Water:

Always dose 6% Cooltreat AL™ in any make-up water added to the system.
Use distilled water to minimize chloride levels and maximize corrosion protection.
