buy AdBlue

1. buy AdBlue AdBlue® Product AdBlue® is a 32.5% solution of urea in deionized water and is required by many commercial vehicles operating on South Africa’s roads. AdBlue® is essential for the correct operation of an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction or SCR. Unlike diesel, AdBlue® is a clear, non-toxic liquid that is safe to handle and does not damage the environment. AdBlue® is not a fuel or fuel additive. AdBlue® is a high specification solution and is manufactured to the DIN 70070 and ISO 22241 standards. WHO NEEDS AdBlue®? Currently, AdBlue® is required by the majority of heavy duty diesel vehicles (trucks, buses and coaches) purchased after October 2006.

2. In order to meet the Euro IV and V emissions limits, all of the major South Africa truck makers, to a greater or lesser extent, offer SCR equipped vehicles. However, MAN and Scania have a firm focus on an alternative technology called EGR that does not require the use of AdBlue® and have equipped the majority of their model ranges accordingly. It is important to ensure that the vehicles remain supplied with AdBlue®, as an on-board policing system will enforce a torque penalty if the AdBlue® tank is empty. This is to ensure that the vehicles NOx emissions remain below the legal limit. WHAT IS SCR? SCR, or Selective Catalytic Reduction, is an emissions control technology first employed on coal-fired power stations to clean oxides of nitrogen (NOx) from the exhaust gasses. In 2006, the technology successfully crossed into the European heavy-duty diesel market, where it enabled trucks to meet the Euro IV and V limits. An SCR system uses AdBlue® and a vanadium or base metal catalyst mounted in the vehicle's muffler to reduce NOx to water vapour and atmospheric nitrogen. This reaction takes place downstream of the engine in the exhaust system and is known as "after-treatment". Unlike the alternative EGR technology - championed by MAN and Scania - SCR tackles the problem outside of the engine and has the potential to achieve >80% NOx reduction rates, allowing the engine to be tuned for maximum efficiency. Having the engine set up for maximum efficiency allows for an estimated fuel saving of 3-5%, giving operators the opportunity to save thousands on their annual diesel fuel bills.

4. AdBlue® can be purchased by the Airnox on the road at a truck stop, service station or manufacturer dealership. It is also possible to arrange for a supply of AdBlue® direct to the haulier's base of operations. You can use Find AdBlue®.com to find the nearest AdBlue® supply point and information about home base AdBlue® supply. FindAdBlue.com has details of over 10,000 AdBlue® supply points throughout South Africa. While the price of AdBlue® is lower when purchased in bulk at the home depot, this method can incur costly installation and equipment fees. In fact, some operators prefer the convenience of roadside AdBlue® refilling. Indeed, AdBlue® refilling is often linked to the operator's diesel refuelling strategy. AdBlue® is used by the SCR system at a rate equivalent to 5% of diesel consumption and is currently less than half the price of diesel, per litre. CAN I MAKE MY OWN AdBlue® ? No. AdBlue® is a high purity chemical solution manufactured to a strict specification and distributed through a secure supply chain. It is highly unadvisable to attempt to create your own 32.5% urea solution from fertilizer grade urea and water-purified or otherwise. Remember - using a non DIN/ISO specification urea solution will probably result in catalyst damage, invalidating the vehicle's warranty!
