Model Details

Doosan Portable Power delivers the coolest and quietest mid-range T4F package on the market. At 100% load, the G325 Tier-4F generator delivers 334kVA (267 kW0 at 76 dB(A), even with an optional variable speed fan. Doosan Portable Power also offers the G325 with a Tundra Package, enabling enhanced performance in the most extreme temperatures. This package ensures reliable startup in temperatures as low as -40˚F/˚C and includes a coolant heater, oil pan heather, battery charger, battery heater pad, and heated breather hose.

The G325 is powered by a fuel efficient Tier 4F-compliant Cummins QSL9 engine with improved fuel economy, able to power the G325 for 24-hours straight at 100% load. In addition to this improved T4F engine, the G325 is equipped with a Leroy-Somer alternator with AREP excitation, protecting against overload and short-circuits while offering voltage stability and greater motor starting capability. Doosan Portable Power continues its industry leading serviceability with 500-hour service intervals.

The G325 features an improved analog control panel that has been enhanced with large, brightly lit meters for quick monitoring. This operator-preferred control panel displays onboard engine diagnostics and includes all the necessary controls and indicators required to operate and maintain the after treatment regeneration system. A run/idle switch on the control unit ensures reduced engine wear during startup in extreme cold temperatures. Dual frequency capability is now standard throughout the Tier 4 portfolio, further expanding the already versatile machines to power 50 Hz applications with the simple flip of a switch. An additional standard feature is the Voltage Selector Switch, providing quick and easy voltage configuration. The Voltage Selector Switch is a signature Doosan Portable Power protection feature that prevents the operator from switching voltage during operation- a common cause of downtime and expensive repairs.

Connection panels are now more accessible for improved safety and convenience. These panels have been expanded with more power wiring connections available, an optional camlock panel to further expand connection versatility, an array of twist-lock and GFCI receptacles and a terminal board that accepts bare wire or lugged cables.
