Why is AdBlue® quality so important?

A new vehicle or machine is a significant investment, and keeping it operating efficiently and profitably is crucial. AdBlue® plays a vital role in reducing emissions by being injected into a catalyst system. However, to ensure its effectiveness, it is essential to prevent contamination from certain elements that can block the catalyst’s active sites. Such blockages can reduce the efficiency of the emission control system, leading to higher pollutant levels. This may trigger the vehicle’s ECU to limit engine power and, in some cases, require expensive catalyst replacement. Additionally, catalyst blockage can increase engine back pressure, negatively impacting fuel economy.

Common tap water contains elements like Calcium and Magnesium, which can cause scale buildup—similar to deposits in kettles or geysers. This scale cannot be removed once formed in the catalyst, so it is important never to fill tap water into the AdBlue® tank. Other elements of concern include Iron, Aluminium, and Copper. While these are not typically present in water, they can enter AdBlue® through unsuitable storage tanks, pumps, or pipework. Since AdBlue® is mildly alkaline, it can corrode materials like mild steel, aluminium alloys, and brass, allowing these metals to dissolve and be deposited onto the catalyst, causing irreversible damage. To avoid these issues, always use certified AdBlue® and compatible storage and handling equipment.
