AdBlue®
Description & Use

Services

AdBlue is used to treat exhaust gas produced by a diesel engine.

Vehicles using AdBlue have a Selective Catalytic Reduction (SCR) technology which reduces harmful gases released into the atmosphere. 

NOx molecules in the exhaust are converted to harmless nitrogen and water.

AdBlue is a mixture of 32 5 % urea solution of high-purity diluted and de-mineralized water.

“’ISO 22241 specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution) which is needed to operate converters with selective catalytic reduction so-called SCR (Selective Catalytic Reduction) converters in motor vehicles with diesel engines. SCR converters are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of diesel engines”’
