DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) is an emissions control liquid required by modern diesel engines. It is injected into the exhaust stream.
DEF is never added to diesel fuel. It is a non-hazardous solution of urea and de-ionized water.
DEF is used in Selective Catalytic Reduction (SCR) technology to remove harmful NOx emissions from diesel engines.
In January 2010, the U.S. EPA brought in new emissions standards requiring medium- and heavy-duty vehicles to significantly reduce engine emissions, particularly NOx and particulate matter (PM).
Hightowers Petroleum Co. has the ability to provide this in gallon, drum, tote or bulk tanks on a national platform.
