AUS 40 – High-Quality Marine Urea Solution by BlueOne®

At BlueOne, we specialize in providing high-purity liquid solutions tailored for modern emissions control technologies. Among our flagship marine-grade products is AUS 40 (Aqueous Urea Solution 40%), a vital additive used in reducing NOx emissions from large marine engines operating with SCR (Selective Catalytic Reduction) systems.

AUS 40 is not just a chemical product – it’s part of our commitment to cleaner oceans, regulatory compliance, and operational efficiency for your vessels. Manufactured in compliance with ISO 18611, our solution ensures maximum performance, minimal emissions, and complete safety for marine diesel applications.

Unlike conventional urea solutions, AUS 40 is formulated with ultra-pure raw materials and deionized water, achieving a consistent 40% urea concentration with extremely low levels of impurities such as biuret, aldehydes, and heavy metals. Every batch is strictly tested to meet international maritime emission control standards.

BlueOne’s AUS 40 is developed and packaged in Vietnam, close to major shipping ports and export hubs, helping you reduce lead times and logistics costs. Whether you’re managing a shipping line, offshore supply vessel, or a bulk carrier fleet, we ensure seamless supply with professional service.
