How to Distinguish Between Qualified and Unqualified Urea Solution

The concentration of the urea solution is one of the key factors. The concentration of urea solution directly affects the catalytic efficiency of NOx and the freezing point of the urea solution, and also affects the parameter setting of the aftertreatment system. The concentration of the high-quality automotive urea solution must be within the specified range.

Here is the our product test report from SGS and we strictly follow ISO22241 standard to produce the AdBlue . 

The impact of the quality of urea solution on the spray accessories of the SCR system. The combustion of insoluble impurities produces carbon deposits, which affects the spray accessories of the post-processing system, which will block the catalyst framework and reduce the efficiency and service life of the catalyst. The impurities will cause damage to the air pump.

The quality of vehicle urea affects the SCR system catalyst. SCR catalyst is the core of SCR reduction technology, and SCR catalyst is one of the core of SCR catalyst. The activity of the catalyst is very important to improve the conversion efficiency of the entire SCR system. The index of aldehydes in urea for vehicles is stipulated to be below 5ppm. Aldehydes may affect the coating of the catalyst in the SCR system.

The generation of deposits is a common problem in the use of urea solutions. The production of sediments has seriously affected the operation of the SCR system, and even caused blockage of the pipeline, corrosion of the deposition area, and blockage of the catalyst channel, which ultimately made the SCR system ineffective. 

High-quality urea solution will greatly reduce the generation of sediments.
