Product Description
Pure Machine Aus32 Industrial Grade Technical Def Urea
Description of low biuret urea 99% high purity NO Reduction Agent SCR UREA with SGS testing
What is SCR?----SCR (Selective Catalytic Reduction) transforms the harmful nitrogen oxides (NOx) in the exhaust of 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 ammoni a which then reacts with the NOx in the exhaust gas.
What is DEF?----DEF is aqueous urea solution used in SCR systems on vehicles. SCR Urea complies with ISO 22241-1 and DIN 70070 standards
why ourSCR urea can be making DEF?----The raw material of our urea is pure 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.

Currently,our DEF urea has passed the testing in Amalgatech,SGS What is Selective Catalytic Reduction (SCR)?
chemical reactions used in SCR system require a constant feed of ammoni a gas.In automotive applications SCR delivers ammoni a using
a urea solution called Exhaust Fluid(DEF).

Q4: I have experienced cakin problems when I bought urea from another supplier several months ago, does your urea have same problem?
