AWM DEF BLUE™

AWM® DEF BLUE™ is a fluid for SCR systems of diesel engines

AWM DEF BLUE™ is an urea solution of high level purification (32.5%) in demineralized water (67.5%).
AWM® DEF BLUE™ is a complete analogue of urea solution AUS 32 (Aqueous Urea Solution, 32.5%), also delivered under AdBlue®brand, registered by the German Association of the Automotive Industry (VDA).

It is used as an additional service fluid in SCR (Selective Catalytic Reduction) systems of diesel engines.

SCR technology is based on injection of accurate dosed quantity of DEF (Diesel Exhaust Fluid) reagent in the flow of waste gases at the availability of catalyst (vanadic pentoxide). As a result, a chemical reaction of toxic nitrogen oxides (NOx) transformation into harmless substances – nitrogen and water - takes place.
Application of SCR systems in the system of heavy equipment engine exhaust is required to achieve ecological norm and standards Euro 4 and Euro 5 on harmful agent emission.

AWM® DEF BLUE™ is produced in strict accordance with industrial standards: DIN 70070 and ISO 22241 as well as with the requirements of OEM specifications.
