Diesel Exhaust Fluids (DEF) Services

Diesel Exhaust Fluids (DEF) and Selective Catalytic Reduction (SCR)

Diesel Exhaust Fluid is combined with SCR technology. SCR stands for an after treatment technology called Selective Catalytic Reduction. This technology requires the use of an operating fluid known as Diesel Exhaust Fluid (DEF) to reduce the Nitrogen Oxides (NOx) in the emissions. Almost all major diesel engine manufacturers have decided to use this SCR technology to meet the new emission regulations on NOx reduction. SCR is the most cost effective solution to meet NOx emission standards of the EPA Clean Air Act.

There are different emission standards around the world, setting specific NOx emission limits that require the use of SCR and Diesel Exhaust Fluid (DEF). The four main pollutants covered by vehicle emission legislation are Nitrogen Oxide (NOx), Particulate Matter (PM), Carbon monoxide (CO), and Hydrocarbons (HC).

In the USA, emissions diesel engines are regulated by the EPA’s Clean Air Act.

The use of SCR System for NOx reduction is an efficient way to meet these regulations, which went into effect on January 1, 2010 and sets the NOx emission limits at 0.20 g/bhp-hr.
SCR systems are sensitive to potential chemical impurities in the Diesel Exhaust Fluid solution. Even small amounts of impurities can severely damage the performance of the SCR system.

Shelf life and usability of DEF can be affected by temperature and time. We strongly urge to have your stored DEF laboratory tested annually to insure usability.
