AdBlue ISO 22241

AdBlue is stored in a separate tank to diesel and is added to the exhaust fumes prior to them being expelled from the vehicle. Using AdBlue drastically reduces NOx, carbon monoxide and particulate emissions, reducing the environmental impact of your fuel consumption.

ISO 22241 is an internationally-recognised standard that indicates the quality, physical and chemical properties of AdBlue. All AdBlue tanks and diesel engines are built with ISO 22241 in mind which is why it’s important that your AdBlue is of the highest quality and meets this standard. At Beesley Fuels we’re a trusted supplier of high-quality AdBlue with over 50 years of experience in the fuel industry.
