USA DEF continues to manufacture

the highest quality product for your DEF needs.


Reduce Emissions

Environmental Protection Agency (EPA) diesel emission mandates are driving changes to the equipment used on vehicles.

Selective Catalytic Reduction (SCR) is the key technology chosen by most car/truck OEM’s. The catalyst in the SCR unit consumes DEF to convert the NOx in the exhaust gas into nitrogen gas and water.

Cut Fuel Costs

Reduce fuel consumption and operate your fleet more efficiently.

SCR reduces NOx emissions to extremely minute levels, while at the same time delivering improved fuel economy and reliability. By treating the exhaust gases outside of the engine, SCR technology can provide up to 5% better fuel economy.
