    Wholesale Urea Adblue Manufacturing in Diesel Tank Adblue ...
    AdBlue® (also known as DEF or AUS 32) is a 32.5% high-purity urea solution used in Selective Catalytic Reduction (SCR) technology to treat diesel exhaust fumes. It reduces harmful nitrogen oxides (NOx) into harmless nitrogen and water vapour, helping engines comply with Euro 5/6 and modern emission standards. 
    Key Aspects of AdBlue/AUS 32 for SCR Systems 
    • Composition: Composed of 32.5% synthetic urea and 67.5% demineralized water.
    • Function: It is injected into the hot exhaust gas, where it decomposes into ammonia and breaks down NOx in the SCR catalyst.
    • Compliance: Required for most modern diesel vehicles (trucks, cars, tractors) fitted with SCR.
    • Standards: Manufactured to comply with ISO 22241 standards to ensure purity and prevent damage to the SCR catalyst.
    • Storage & Handling: Non-toxic and non-flammable, but can corrode certain materials and freeze at
      -11.5∘Cnegative 11.5 raised to the composed with power cap C
      −11.5∘𝐶
      .
    • Consumption: Generally consumed at a rate of roughly 1 liter per
      100100
      100
      kilometers, though this depends on the vehicle and driving conditions.
       
    SCR Technology Summary
    Selective Catalytic Reduction (SCR) is an active emissions control system that adds a gaseous or liquid reducer—specifically, the AUS 32/AdBlue urea solution—into the exhaust stream of a diesel engine. This system is considered the most cost-effective solution for reducing nitrogen oxides to meet stringent environmental legislation. 
    Common Names 
    • AdBlue: Registered trademark (common in Europe).
    • DEF (Diesel Exhaust Fluid): Common in North America.
    • AUS 32 (Aqueous Urea Solution 32.5%): Technical name.
    • ARLA 32: Common in Brazil. 
    Note: If the AdBlue tank is exhausted, modern engines cannot be restarted.

    Are SCR and AdBlue the same?
    SCR stands for selective catalytic reduction, which is a technology used for reducing nitrogen oxides (NOx) from the exhaust gas of diesel engines. It's based on AdBlue® - also called diesel exhaust fluid - a 32.5% urea solution in purified water, which is injected into the exhaust pipe.

    Is SCR the same as DEF?
    The SCR system substantially lowers the NOx emissions in the exhaust through a catalytic reduction process. An SCR system spreads an aqueous solution that contains 32.5% urea in the exhaust stream. This solution is known as Diesel Exhaust Fluid (DEF).Jul 19, 2024
