About Us

Because authorities have tightened air pollution standards, today's engine manufacturers have responded with Selective Catalytic Reduction (SCR) technology which uses urea to neutralize harmful Nitrogen Oxide (NOx) emissions.  The operating fluid for SCR systems is called Diesel Exhaust Fluid (DEF).


USA DEF works with SCR technology to reduce harmful emissions in everything from truck engines to factory furnaces.  When injected into the SCR catalyst, USA DEF converts harmful nitrogen oxides from all kinds of combustion engines into harmless water vapor and nitrogen.

USA DEF Benefits Go Beyond Environmental Issues

The combination of USA DEF and SCR technology equals power.  Not only are cleaner emissions achieved but overall fuel efficiency improves when compared to other technologies.  With USA DEF, you'll not only enhance your green reputation but you'll operate more efficiently as well.

In addition to cutting fuel costs and reducing emissions, USA DEF is your most reliable resource for a high purity urea solution that is needed to convert harmful nitrogen oxides into harmless water vapor in SCR vehicles.
