AdBlue® AUS 32

AdBlue ® AUS 32 details

AdBlue ® AUS 32 is manufactured following the ISO 22241 standard. ISO 22241-1:2006 standard specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution or diesel exhaust fluid). AUS 32 is necessary for selective catalytic reduction converters to work correctly. Usually, we can find these SCR systems in diesel vehicles equipped with EURO 5 and EURO 6 emission standard engines and exhaust systems.

The main role of the AUS 32 agent is to provide NH3 (ammonia) into the exhaust system of the diesel engines for NOx reduction. AdBlue ® AUS 32 is made of 67,5% deionized water and 32,5% high-purity industrial Aqueous Urea Solution. Exposure to high exhaust gas temperature decomposes AUS 32 to ammonia. AUS 32 solution freezes at -11,5 degrees C (eutectic mixture in a partially frozen state, the unfrozen solution remains at 32.5%). AdBlue ® AUS 32 expected consumption level is about 3 to 5 percent of fuel consumption, it depends on engine, exhaust and environment temperature, also on the engines load level and RPMs.
