Their products are known for reliability and performance in the most demanding marine environments.
Whether you’re treating water, managing fuel systems, or maintaining onboard hygiene, this brand offers a solution tailored to your needs.
A Trusted Name in Marine Chemical Solutions
From cruise liners to commercial vessels, reliable chemical treatment can mean the difference between smooth sailing and costly delays. With a reputation for quality, it has earned the trust of vessel operators, engineers and fleet managers across the globe.
Developed to meet tough maritime challenges, the products not only support sustainability and regulatory compliance but also help reduce system downtime, extend equipment lifespan, and ensure safety at sea.
Engineered for Real-World Marine Applications
Imagine a vessel forced into unscheduled maintenance due to undetected corrosion in the cooling system, it’s an unavoidable situation, if the right chemicals are in place. This is where NALFLEET’s advanced formulations come into play, addressing the most common risks across key systems like the boiler water, cooling water, potable water and fuel.
Without regular treatment, these systems are vulnerable to scale, corrosion, microbial growth and contamination, which leads to costly repairs, safety hazards and service interruptions
Protecting Boiler Performance with the Right Treatment
Picture boiler pressure dropping mid journey Boiler systems are essential for energy transfer on many vessels, but untreated boiler water can quickly degrade performance fast. There are a range of chemical and conditioners available that helps protect boiler systems, reduce downtime, cut operating costs and maintain consistent steam quality.
Keeping Cooling Systems Safe from Corrosion and Bacteria
Did you know that untreated cooling systems can foster Legionella bacteria? Marine cooling systems are vulnerable to scaling, fouling, and corrosion which can compromise safety and performance. To prevent this, they offer corrosion inhibitors, cleaning treatments, alongside monitoring solutions to help crews manage risk and maintain efficiency.
Protecting Drinking Water Quality Onboard
Access to clean drinking water isn’t just about comfort, it’s compliance. Hygiene lapses can lead to outbreaks of harmful bacteria onboard. The brand’s potable water stabilisers and corrosion inhibitors are designed to maintain cleanliness in pipes and tanks, supporting safety standards and system longevity.
Improving Fuel System Efficiency and Preventing Contamination
Contaminated fuel can reduce engine performance and increase maintenance costs. To combat this, a selection of cleaning and conditioning chemicals is available to boost fuel efficiency and protect sensitive systems. These are complemented by cleaning products that help maintain vessel interiors and exteriors.
Popular Products Trusted by Marine Professionals
One of our most popular items is NALFLEET 2000, a liquid treatment that combines film-forming corrosion inhibitors with scale suppressants. It’s highly soluble and chromate free, it protects a wide range of metals, including ferrous metals, copper and aluminium. Its versatility and ease of use makes it a favourite among marine engineers.
Another essential product is the NALFLEET Water Test Kit, which allows crew members to monitor the quality of potable water onboard. Poorly managed water can be a route for infectious diseases like E. coli or other coliform bacteria. This kit includes everything needed to test for harmful bacteria, chlorine levels, and pH, alongside tools like a UV lamp and incubator for on-the-spot analysis.
