SCR Urea

1) Description:
SCR----SCR (Selective Catalytic Reduction) transforms the harmful nitrogen oxides (NOx) in the exhaust of diesel vehicles into harmless nitrogen gas and water vapour. The SCR solution is metered into the exhaust system in front of a catalyst. The urea hydrolyses to ammonia which then reacts with the NOx in the exhaust gas.
DEF----DEF is aqueous urea solution used in SCR systems on diesel vehicles. SCR Urea complies with ISO 22241-1 and DIN 70070 standards
SCR urea can be making DEF----The raw material of our urea is pure natural gas, so that the urea is with low Biuret, low Aldehydes and low heavy metal materials; We have the most advanced production equipment and testing equipment.
