The qualified AdBlue® is a high-purity transparent liquid composed of 32.5% high-purity urea and 67.5% deionized water. It has a light ammonia smell and is suitable for all Euro IV and Euro V emission diesel engine with SCR system.

The fertilizer urea prilled will cause the catalyst poisoning and damage parts of SCR tail gas processors by its excessive biurea , mechanical impurities , formaldehyde and metal ions . It is a big loss for the user if the unrecoverable damage occurs .

In addition , fertilizer urea is easy to crystallize at low temperature and can not guarantee the concentration of urea solution, resulting in low conversion of nitrogen oxides. And the loss of ammonia will damage the SCR system so that the vehicle can not meet the emission standards.

The harms of using the agricultural urea instead of industrial urea or using the water instead of AdBlue® are as follows:

1. Agricultural urea is easy to crystallize at low temperature.

2. Causing the damage of SCR systems .

3. High emissions of PM and NOx.

4. The vehicle can not meet the emission standards .

5. NOx will lead to acid rainpollution,photochemical smog pollution.

6. The contaminant will do harm to people’s health.

The characteristics of EverBlue industrial grade urea

1. Low content of biuret.
The content of biuret within 0.8%, thus the biuret of adblue entirely meet the
standard of 0.3%.
2. Low content of aldehydes.
The content of biuret within 1 ppm .
3. Low content of Insoluble.
4. Low content of metal ions.
Therefore, the urea is very pure and its color is snow white.
