About DEF

A non-additive solution to breaking NOx emissions into less impactful nitrogen and water.

Due to emission standards adopted by the U.S. Environmental Protection Agency in 2010, more and more trucks and engine manufacturers are using DEF in a system called Selective Catalytic Reduction (SCR). This technology allows medium- and heavy-duty vehicles to break down NOx emissions into harmless nitrogen and water, thus reducing their impact on the environment. DEF and SCR technology allow vehicles to meet newly adopted standards without compromising engine performance and fuel efficiency. At SCL, we not only deliver DEF to your facility, we can guide you on how and where to store it, correct applications in your vehicles, and we can even monitor your tank to ensure you never run out of supply.
