  • The G125-150 models include the upgraded CoolBox Plus™ enclosure design which adds a temperature-controlled, variable-speed cooling fan to the package.
  • This allows enhanced performance in extreme ambient temperatures while further improving sound attenuation and reducing water ingression across the operating range.
  • Doosan’s advanced controls include an LCD display which annunciates any warnings or shutdowns. In addition, the controller logs all system faults, greatly aiding technicians with diagnostics.
  • The system also supports remote auto start/stop control, plus integration with various telematics systems.
  • The G125-400 range is powered by Cummins tier 4-compliant diesel engines, paired with high capacity diesel exhaust fluid (DEF) tanks to ensure the DEF supply is matched to the available fuel supply.

Doosan mobile generators produce a broad range of output voltages thanks to the standard three-position voltage selector switch or link board panel. The voltage change feature is protected from unauthorized access and will shut the machine down to prevent switching during operation. The customer connection panel is spacious and designed to accept a wide variety of power cables. The convenience receptacle panel includes 240V single phase twist-lock receptacles and 120V GFCI receptacles that are powered any time the unit is running.
