NALFLEET™ Cooltreat AL™
NALFLEET™ Cooltreat AL™ is an extended-life organic corrosion inhibitor designed to protect marine cooling water systems, including systems containing aluminium components.
Advanced Corrosion Protection for Cooling Water Systems
NALFLEET™ Cooltreat AL™ is a high-performance organic corrosion inhibitor developed for closed recirculating cooling water systems. Using advanced aliphatic acid technology, the product forms a thin molecular protective layer on metal surfaces that prevents corrosion without creating heavy insulating deposits.
Unlike traditional nitrite and silicate-based treatments, Cooltreat AL™ is a stable, non-depleting formulation that provides long-term protection while helping maintain efficient heat transfer throughout the cooling system.
Amalgam Biotech supplies genuine marine water treatment chemicals across India for shipping companies, offshore operators, marine contractors, and industrial cooling system operators.

Key Benefits
Protects ferrous and non-ferrous metals
Safe for aluminium components
Reduces corrosion risks
Helps prevent cavitation damage
Maintains cooling efficiency
Requires less frequent testing
Supports long-term system reliability
Supports Efficient Heat Transfer
Traditional corrosion inhibitors can gradually create insulating deposits on heat transfer surfaces, reducing cooling efficiency over time.
NALFLEET™ Cooltreat AL™ protects metal surfaces using a thin molecular layer rather than heavy oxide deposits. This helps maintain efficient heat transfer throughout the cooling system while still providing long-term corrosion protection.
The result is improved cooling performance and greater operational efficiency for engines and auxiliary equipment.

Directions for Use
NALFLEET™ Cooltreat AL™ should be dosed directly into the cooling water system at a suitable dosing point with adequate circulation.
Typical initial dosage:
6% concentration for untreated systems
Up to 8% concentration when used with glycols for freeze protection
Regular monitoring is recommended to maintain optimum treatment levels and cooling system performance.
Why Choose Cooltreat AL™ Instead of Conventional Treatments?
Many conventional cooling water treatments rely on nitrites and silicates that gradually deplete during operation and require regular replenishment.
NALFLEET™ Cooltreat AL™ uses modern organic acid technology that remains stable for extended periods. Rather than building thick oxide layers on metal surfaces, the treatment forms a durable molecular barrier that protects against corrosion while preserving efficient heat transfer.
This approach helps improve cooling performance while reducing treatment maintenance requirements.
Ideal for Systems Containing Aluminium
Aluminium components require special consideration in cooling water treatment programs. Certain traditional corrosion inhibitors may not provide adequate protection for aluminium alloys used in modern engines and cooling equipment.
NALFLEET™ Cooltreat AL™ is specifically formulated to protect:
Aluminium components
Steel components
Copper alloys
Brass materials
Mixed-metal cooling systems
This makes it an ideal solution for modern marine engines and auxiliary equipment where aluminium protection is essential.
Protection Against Corrosion, Cavitation & Erosion
Marine cooling systems face several operational threats beyond standard corrosion. Cavitation and erosion can gradually damage pumps, cylinder liners, and cooling system components, leading to costly maintenance and downtime.
NALFLEET™ Cooltreat AL™ helps protect against:
Corrosion
Cavitation
Erosion
Acidic attack
Cooling system deterioration
The result is improved system reliability and longer equipment service life.
