DEF- Diesel Exhaust Fluid
New Diesel Engines?
Ask us about our ultrapure diesel exhaust fluid. Diesel Exhaust Fluid (DEF) is an ULTRA-PURE UREA solution that acts as a reductant. It is carried in a separate tank, and is then injected into the hot exhaust stream and absorbed onto a catalyst.
All future trucks will have separate DEF tank for delivery to customers on construction sites or trucking fleets.
