🔵 What is AdBlue?

AdBlue is a high-purity, colorless liquid made from deionized water and pharmaceutical-grade urea (32.5%). It is used in diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology to reduce harmful nitrogen oxide (NOx) emissions. When injected into the exhaust system, AdBlue reacts with exhaust gases and converts NOx into harmless nitrogen and water vapor — helping diesel engines meet Euro 6 emissions standards.

🚛 Why AdBlue is Essential for Modern Diesel Engines

With tightening environmental regulations across the UK and Europe, AdBlue has become essential for the efficient and legal operation of diesel vehicles. It not only helps reduce environmental pollution but also improves engine performance and fuel efficiency in SCR-equipped engines. Using certified AdBlue ensures optimal SCR function, prevents system damage, and avoids costly repairs.

🧪 Purity Matters: Why Quality AdBlue is Critical

Poor-quality AdBlue or improper handling can damage the SCR system, clog injectors, and lead to increased emissions or vehicle downtime. That’s why DEolizet Water Company provides high-purity, ISO 22241-compliant AdBlue, manufactured under strict quality control using ultra-pure deionized water and urea.
