What is urea/def
Def/urea is a 32.5% solution of urea in deionised water and is required by many commercial vehicles operating on Europe's roads. AdBlue is essential for the correct operation of an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction or SCR. Unlike diesel, AdBlue is a clear, non-toxic liquid that is safe to handle and does not damage the environment. AdBlue is not a fuel or fuel additive.
AdBlue is a high specification solution and is manufactured to the DIN 70070 and ISO 22241 standards。
