Composition of AUS32
AUS32 is the urea catalyst especially used for diesel engine. It is harmless, tasteless and having no danger. It is very safe and can be operated conveniently.
The active material of AUS32—urea, is made by natural gas.

Urea is a kind of white crystal power. It is existed commonly in the environment. It is a kind of stable and harmless material, having no limit on storage and transportation.

The density of the urea is required to be 32.5%.

Such high-pure urea solution has several different names, such as in North America, it is called DEF, in Europe, it is usually called AdBlue. And AdBlue is the trademark entrusted with protecting and enforcing and has been established a licensing system by VDA. While DEF is the official trademark owned by API. And we are the first as well as the only enterprise who has gained the API DEF certificate in China.

Using of AUS32

The most important part in SCR converter is AUS32. Before it is transported into the catalyzing converter, it has been transformed into ammonia by hot exhaust gas. The ammonia and nitrogen oxide which is of the catalyzing converter generate the chemical reaction, transforming into nitrogen and water, so as to reduce the emission of nitrogen-oxidation compounds and particles. At the same time it can also prevent the further global warming.

Packing Types
10kg, 18kg, 200kg, 1000kg

Product Performance
1.It is the NOx selective catalytic reducer, composed by 32.5% ultra-pure urea and water. It is suitable for all SCR systems of European IV and V emission diesel engines. It is the standard equipment of SCR technology.
2. It is transformed into nitrogen and water by generating the selective catalytic reducing reaction with Nox, so as to reduce the emission of nitrogen-oxidation compounds.
3.The SCR technology can effectively decrease the oil consumption as well as the emission of nitrogen-oxidation compounds.
