Description
NALFLEET™ Cooltreat AL™ – Organic Corrosion Inhibitor for Closed Cooling Water Systems
NALFLEET™ Cooltreat AL™ is an advanced organic liquid corrosion inhibitor designed for use in closed cooling water systems, including systems with aluminium components.
It does not contain fast-depleting components such as nitrite or silicate and is based on aliphatic acid technology.
The product provides long-term protection, reduces testing frequency, and is fully biodegradable.
Features
-
Effective protection against corrosion, erosion, and cavitation in metal cooling circuits
-
Compatible with hoses, gaskets, seals, and common glycols for freeze protection
-
Maintains efficient heat-transfer performance by preventing deposits and scaling
-
Environmentally friendly – fully organic, low toxicity, and biodegradable
Benefits
-
Extends the life of cooling systems and machinery
-
Reduces downtime and maintenance costs
-
Suitable for all types of closed recirculating systems, including diesel engines, compressors, hot-water heating, and auxiliary machinery
-
Safe for aluminium and other sensitive metals
-
Ideal for both marine and industrial applications
Applications
Cooltreat AL™ is designed for:
-
Marine engines and auxiliary cooling systems
-
Offshore installations and industrial plants
-
Closed water circuits in compressors and heat exchangers
-
Systems containing aluminium or mixed metal components
Dosage and Control
For untreated or new systems, use approximately 6 % (60 L per 1000 L of untreated distilled water) to achieve long-term protection.
Cooltreat AL™ is the preferred inhibitor where aluminium is present.
Use an approved cooling water test kit to monitor inhibitor concentration and maintain the correct protection level.
| Concentration | Protection level |
|---|---|
| 5 % | Standard protection |
| 6–10 % | Enhanced protection for demanding systems |
