The recent move of European emission regulations, towards the implementation of Stage IIIA engines in mobile generators, is also an opportunity for Doosan Portable Power to launch a new generator platform design.

This new product range is the result of a close partnership with our customers in the field, listening to the feed-back carried by their voice and translating it into product improvement features.
The flexibility offered by the new G150-IIIA will allow customers to choose the product configuration that best matches the needs. All has been designed to increase reliability, safety of use and accessibility on the jobsite, whatever the application is. From larger road work with concrete or asphalt batch plants or construction sites with tower cranes, structural welding work sites, shipyards, major concerts or events, to the most demanding industrial application, the new G150-IIIA will power your productivity!

The Doosan Portable Power G150-IIIA generator is built around a reliable powertrain, featuring a John Deere EU Stage IIIA engine coupled to a Leroy Somer alternator with standard heavy duty winding impregnation. The AREP alternator excitation system is a standard feature, providing additional electric motor starting capability, compared to shunt alternators.
Powertrain sizing is critical to ensure stable and reliable generator electrical output and provide a strong load take-over performance.

A 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. Integrated steps and handles improve the access safety to the central lifting eye.
Handling operations have been made easy by the standard combination of central lifting eye and forklift pockets integrated in the frame.
The accessibility to the generator maintenance points has been optimized to reduce field intervention times.

The standard G150-IIIA configuration includes a 500l fuel tank to reach 15 hours runtime @ 75% of the load, an extended runtime fuel tank configuration is available from options list. Our innovative frame design allows easy interchangeability between 12-24 hours fuel tank modules. In addition to this, enhanced accessibility to the fuel tank, for cleaning and draining operations, is providing the best help to reduce impact of poor fuel storage on the engine performance.

An optional switchable dual frequency 50/60Hz feature, combined with a digital control panel, provides the G150-IIIA with the best versatility and application conditions monitoring system.
The availability of synchronization option for this platform will provide maximum flexibility and adaptability for rental companies. This allows to use two or more generators, of same or different electrical output, in parallel with the best flexibility to optimize the match between electricity production and demand from the load.
Grouping operator's interface, control panel and electrical protection devices in the same area, drastically improves the safety of use of our generators.
