AdBlue ® is a solution of extremely high-purity, synthetically manufactured urea in de-mineralized water. It is used in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the atmosphere. The use of AdBlue ® reduces fuel consumption of a vehicle. Compared to EURO 3 engines, particulate matter emissions are reduced by approximately 40%, and nitrogen oxide emissions are reduced by up to 90%. AdBlue ® is non-hazardous to humans, non-toxic to the environment and non-flammable. It poses an extremely low hazard to waters. AdBlue ® is supplied in tank trucks, 1000 L containers, 205 L drums and 10 L and 5 L bottles, which are sealed and marked in accordance with regulations. It is stored for up to 1 year in closed containers in warehouses, protected from the effects of extreme temperatures and direct sunlight. The optimal storage temperature is -5 to + 25°C.
