The SDMO D-Series uses Doosan diesel engines to cover the mid-to-large commercial standby segment from 150 to 700 kW. Doosan's inline-six platforms deliver strong power density at a competitive price point, making the D-Series a cost-effective alternative to comparably sized units from Cummins or Caterpillar.
SDMO integrates each Doosan engine with a heavy-duty alternator, digital paralleling-ready controller, and weather-protective enclosure options. The D-Series is a practical fit for commercial facilities, manufacturing plants, and municipal infrastructure that need reliable standby power in the 150-700 kW class without the premium pricing of Tier 1 OEM packages.
