Product Description
Diesel Exhaust Fluid (DEF) is a non-toxic solution used in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. Its a mixture of 32.5% urea and 67.5% deionized water. When injected into the exhaust stream, DEF decomposes into ammonia, which then reacts with NOx in the SCR catalyst, converting it into harmless nitrogen and water vapor.
Main FeaturesThis DEF is specifically formulated to AUS 32 Grade and ISO 22241 standards, ensuring optimal engine compatibility and emission reduction. It maintains a neutral pH (9.010.0), has negligible ash content (<0.02%), and is fully soluble in water. Its clear appearance and odorless nature set it apart as a premium-grade solution for all diesel exhaust systems.
Storage and HandlingStore DEF in a cool, dry area away from direct sunlight to maintain its quality. It should be kept at temperatures between -11C and 30C to prevent degradation or freezing. Ensure containers are tightly sealed and made of compatible plastic materials (can, drum, or IBC) to avoid contamination and preserve shelf life.
Application and BenefitsDEF is used in diesel vehicle Selective Catalytic Reduction (SCR) systems to significantly reduce NOx emissions, aiding vehicles in meeting environmental standards. Its high purity and precise chemical composition safeguard engine components, enhance operational efficiency, and contribute to cleaner, compliant automotive operations.
FAQs of Diesel Exhaust Fluid:
Q: How should Diesel Exhaust Fluid be properly stored?
A: Diesel Exhaust Fluid must be stored in a cool, dry location away from direct sunlight, ideally between -11C and 30C. Use compatible plastic containers such as cans, drums, or IBCs to prevent contamination and ensure product integrity.
Q: What is the key use of AUS 32 Grade Diesel Exhaust Fluid?
A: AUS 32 Grade Diesel Exhaust Fluid is used in the Selective Catalytic Reduction (SCR) systems of diesel vehicles to convert harmful NOx emissions into harmless nitrogen and water, thereby reducing environmental impact and ensuring compliance with emission norms.
Q: When does Diesel Exhaust Fluid expire, and how can you tell if it remains effective?
A: DEF generally has a shelf life of 12 to 24 months, depending on storage conditions. It should appear clear and odorless; any change in color or smell may indicate contamination or degradation, signaling that the product should not be used.
Q: Where can Diesel Exhaust Fluid be applied?
A: This fluid is suitable for all diesel vehicles equipped with SCR systems, including commercial trucks, buses, and non-road machinery, making it versatile for a wide range of automotive applications.
Q: What is the chemical composition of this DEF, and why is purity important?
A: The fluid contains 32.5% urea and 67.5% deionized water, in compliance with ISO 22241 standards. High purity is crucial to prevent SCR system damage, ensure consistent emission reduction, and maintain vehicle warranty.
Q: How does Diesel Exhaust Fluid benefit vehicles and the environment?
A: By reducing NOx emissions, DEF helps vehicles meet strict environmental standards, prolongs engine and emission system life, and improves air quality by lowering pollutants produced during diesel combustion.
