Key Advantages
Why Operators Choose
the D-Series Propane
the D-Series Propane
Near zero-emission performance with the same capacity and reliability as the gas D-Series at a lower operating cost.
Near zero emissions
Reduces NOx emissions to under 0.05 levels. 40% cleaner than gasoline, 70% cleaner than current standards. A meaningful step toward sustainability without sacrificing capacity.
