The new G400WCU-T4F mobile generator is the most powerful model in the Doosan Portable Power lineup.

The range-topping G400 features a prime power rating of 322 kW, in a compact package in order to meet a broad range of applications.

Powered by a Tier 4-Final Cummins QSG12, 513-hp diesel engine, the G400 delivers class-leading motor-starting capability. As well, the lightweight package and compact footprint allows for easier transport and requires less space on the jobsite.

Equipped with a 1,900 litre fuel tank, the G400 delivers 20 hours of runtime at 100 per cent load. Doosan Portable Power also paired the large onboard fuel tank with two diesel exhaust fluid (DEF) tanks to ensure DEF supply matches the available fuel supply.

The G400 is designed with the CoolBox Plus enclosure, which features a variable speed cooling fan to ensure precision cooling. This allows enhanced performance in extreme ambient temperatures, improved fuel economy and lower noise levels.

The operator panel includes the powerful TG410 controller and is complemented by a full array of analog gauges, simplifying machine control and monitoring.

The optional Deif AGC4 power management system greatly enhances the capability of the G400 and broadens its capability to support large, critical power projects.

The model is equipped with a link board panel for multi-voltage configuration. Operators are able to select 480V-3Ø; 240V-3Ø; 208V-3Ø and 120/240V-1Ø. Generator versatility is further enhanced with a dual-frequency switch, which allows operators to power 50 hertz applications with the flick of a switch.

Each G400 generator is designed with an environmental containment system that prevents potential fuel or oil spills outside of the package. The system allows operators to focus on the job at hand while safeguarding the environment.


A broad range of options for customizing the 400 to suit specific applications are available, including cold weather packages, remote fuel and DEF connections, battery chargers, camlock panels and remote telematics systems.

Doosan Portable Power generators are designed to withstand rugged transportation and jobsite needs. Built on heavy-duty skid bases, the generators boast a 14-gauge, galvannealed steel enclosure and tandem-axle running gear for easy towing.
