Diesel Exhaust Fluid, is an important component in keeping heavy-duty trucks and other machinery. Diesel Exhaust Fluid DEF is a combination of deionized water and urea combined with special additives that transform harmful nitrous oxide also known as NOx emissions into harmless water and gas.
SPEL DEF Diesel Exhaust Fluid NoNOx is excellent in reducing pollution output to the lowest levels. It works on the principle of Selective Catalytic Reduction (SCR). Using this fluid in diesel-powered vehicles, such as trucks, buses, and tractors, helps to reduce the amount of nitrogen oxides (NOx) emitted into the air by 90%.
