NALFLEET™ ROCOR NB LIQUID™ Supplier in India
ROCOR NB Liquid™ is a high-performance corrosion inhibitor designed to protect marine engine cooling water systems from corrosion, cavitation, erosion, and scale-related damage.
Corrosion Protection for Marine Cooling Water Systems
ROCOR NB Liquid™ is a highly effective cooling water treatment formulated to protect ferrous and non-ferrous metals found in marine cooling systems. The treatment forms a stable protective oxide film on metal surfaces, preventing corrosion caused by electrolytic action between dissimilar metals and helping maintain long-term system reliability.
The product is widely used in diesel engine cooling systems, centralized cooling systems, auxiliary machinery cooling circuits, compressor cooling systems, and hot water heating systems.
Amalgam Biotech supplies genuine marine water treatment chemicals across India for ship operators, offshore facilities, marine contractors, and industrial cooling system operators.

Directions for Use
ROCOR NB Liquid™ should be dosed directly into the cooling water system at a suitable dosing point with adequate circulation.
Regular testing is recommended to maintain optimum treatment levels and ensure continued corrosion protection.
Dosage requirements vary depending on system volume, water quality, and operational requirements.
Why Cooling Water Corrosion Protection Matters
Marine cooling systems contain a variety of metals that operate under demanding temperature and flow conditions. Without proper treatment, corrosion can lead to:
Pitting damage
Reduced heat transfer efficiency
Equipment deterioration
Increased maintenance costs
Premature component failure
ROCOR NB Liquid™ creates a stable protective barrier on metal surfaces, helping prevent corrosion before damage occurs while maintaining proper cooling system performance.
Protection Against Corrosion, Cavitation & Erosion
Cooling systems face multiple threats beyond conventional corrosion. Cavitation and erosion can gradually damage metal surfaces, particularly around pumps, cylinder liners, and high-flow areas.
ROCOR NB Liquid™ helps protect cooling systems by:
Preventing electrolytic corrosion
Reducing cavitation damage
Limiting erosion effects
Controlling acidic conditions
Maintaining stable pH conditions
This comprehensive protection helps improve cooling system reliability and reduce costly repairs.
Compatible with Modern Cooling Systems
ROCOR NB Liquid™ is designed to work safely with materials commonly found in marine cooling systems.
The treatment is compatible with:
Seals
Gaskets
Hoses
Packing materials
Glycol-based freeze protection systems
This compatibility allows operators to maintain corrosion protection without affecting common system components.
Note: ROCOR NB Liquid™ is not recommended for cooling systems containing aluminium components. Where aluminium is present, Cooltreat AL™ is the recommended alternative.
