BRINE CORROSION INHIBITOR
High-performance corrosion inhibitor for brine cooling systems. Provides reliable multi-metal protection and enables safe replacement of chromate-based treatments in marine refrigeration systems.
Description
NALFLEET Brine Corrosion Inhibitor – Advanced Protection for Brine Cooling Systems
NALFLEET Brine Corrosion Inhibitor is a high-performance corrosion protection chemical specifically developed for brine cooling systems operating under both low and high temperature conditions. The formulation delivers reliable, long-term protection for carbon steel and most other metals without the need for supplementary additives.
In addition, the product is fully compatible with systems containing chromates and can be introduced without causing precipitation or operational disruption. This makes it an ideal solution for vessels and installations transitioning away from traditional chromate-based corrosion protection.

Application & Dosing Instructions
The recommended dosage of NALFLEET™ Brine Corrosion Inhibitor is 17.5 litres per tonne of brine in the system. The product may be added directly to the system either neat or diluted with water.
For dilution, evaporated or demineralised water should always be used.
When using a chemical dosing pump, all wetted parts should be manufactured from compatible materials such as mild steel, stainless steel, Teflon, polyethylene, PVC, polypropylene, or rubber.
Conversion from Chromate-Based Systems
NALFLEET™ Brine Corrosion Inhibitor is fully compatible with chromate-treated systems, meaning system flushing is not required prior to conversion. Existing chromate levels should be allowed to deplete naturally.
During conversion:
-
Maintain a minimum boron concentration of 70 ppm
-
Introduce the inhibitor gradually, starting with 5–10% of the total dosage
-
Monitor the system for foaming and increase the feed rate progressively
At normal operating concentrations, the product does not cause foaming. However, rapid overdosing may result in temporary foam formation.
Monitoring, Testing & Control
System control is carried out by measuring boron concentration, which should be maintained within the range of 70–100 ppm.
Because brine density varies with concentration, boron levels must be corrected using the following calculation:
Corrected Boron (ppm) = Measured Boron (mg/L) ÷ Brine Specific Gravity
Refer to the attached boron reference table for accurate interpretation.
