The Doosan Portable Power G20 generator is built around a reliable powertrain, featuring a Mitsubishi Stage IIIA engine coupled to a Leroy Somer alternator. The AREP alternator excitation system is a standard feature, providing additional electric motor starting capability, compared to shunt alternators.
The powertrain sizing is critical to ensure stable and reliable generator electrical output and provide a strong load take-over performance.

The sound attenuating enclosure, built on the frame, allows the complete generator package meeting or exceeding applicable CE noise regulations. The enclosure panels are powder coated, ensuring a good preservation of your invested capital.
Handling operations have been made easy by the standard combination of central lifting eye and forklift pockets integrated in the frame.

The standard G20 configuration features a 150l fuel tank to reach 35 hours runtime @ 75% of the load. The accessibility to the generator maintenance points has been optimized to reduce field intervention times.

Grouping operator's interface, control panel and electrical protection devices in the same area, drastically improves the safety of use of our generators.
