For All Your Diesel Exhaust Fluid Needs
What is DEF?
Diesel Exhaust Fluid (DEF) is a solution of high purity urea and de-ionized water. It is the operating fluid required in vehicles using Selective Catalytic Reduction (SCR) technology. Engineers developed the technology to meet the 2010 emission standards for reducing nitrogen oxide (NOx) exhaust emissions from diesel engines.
The fluid is contained in a designated DEF tank and it is sprayed into the exhaust system before the catalytic converter breaks down NOx into harmless nitrogen and water vapors.
DEF has a shelf life of 12 months if the required storage conditions are followed. However, DEF that has been stowed for a longer period may be usable if analyzed to confirm that it still meets the DEF specification. Storage facilities can be adapted to suit customer needs.
What Are the Benefits Of DEF?
Reduced pollution
The main reason selective catalytic reduction was introduced was to help the environment. Diesel has been known to emit poisonous NOx emissions, typically blamed for causing acid rain and the greenhouse effect. With DEF turning the emissions into nitrogen and water, this is much more environmentally friendly.
Reduced maintenance
Engines designed with SCR technology have less wear and tear on their vehicles than those without, reducing the need for maintenance. Reduced maintenance also means that your vehicle is less likely to break down.
