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 |
