NALFLEET™ Cooltreat AL™ 25 LTR – Organic Corrosion Inhibitor for Engine Cooling Systems
NALFLEET™ Cooltreat AL™ is a biodegradable, organic corrosion inhibitor designed for closed engine cooling systems. Provides long-lasting protection for all common metals, including aluminium.
- Category: Engine Coolant Protection, 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
-
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.
-
1] Reduced Maintenance – Extended system life with minimal upkeep.
2] Improved Efficiency – Superior heat transfer improves performance.
3] Versatile Use – Suitable for various marine and industrial applications.
4] Environmentally Responsible – Eco-friendly formulation that meets modern marine standards.
5] Tested and Approved – Approved by major engine manufacturers.
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.
