The G125 Tier 4i portable generator form Doosan Portable Power has been specifically designed with our Canadian customers in mind. The G125 uses a maintenance-free diesel oxidation catalyst instead of a diesel particulate filter, resulting in no regeneration! The G125 is able to take on the toughest jobs with 25-hours of onboard fuel at 100% load.

The G125 features a durable, rugged design that allows this machine to traverse virtually any terrain. Doosan Portable Power’s legendary hardened running gear and enclosures stand up to the harshest of environments. The G125 is the ultimate in practical versatility- being able to change from 50Hz to 60Hz and from 120/240V-1Ø, 208V-3Ø, 480V-3Ø, and 600V-3Ø with the flip of a switch. The G125 from Doosan Portable Power is the most versatile, maintenance-free, and dependable generators on the market.

The G125 Tier 4i generator form Doosan Portable Power delivers 128 kVA (102 kW) at 67 dB(A) at 100% load with an optional variable speed fan, making it the coolest and quietest mid-range T4i package available today. The G125 T4i features Quad Voltage feature that allows the user to select between 120/240V-1Ø, 208V-3Ø, 480V-3Ø, and 600V-3Ø- all at the flip of a switch. A Dual-Frequency switch increases the versatility of the G125 portable generator, a standard feature that allows the generator to change from 50Hz to 60Hz.  An optional Tundra package ensures enhanced performance even in the most extreme temperatures. The Tundra Package ensures startup and reliable operation in temperatures as low as -40˚F/˚C and includes a coolant heater, oil pan heater, battery charger, battery heater pad, and heated breather hose.

The G125 is powered by a fuel efficient, Tier 4i compliant Cummins QSB5 engine. At 100% load, the G125 T4i can run for 25 hours continuously. To keep the machine up and running, the Cummins engine uses a maintenance-free Diesel Oxidation Catalyst to clean emissions and decrease service intervals. The G125 is equipped with a Leroy-Somer alternator that guarantees voltage stability and greater motor starting capability.

A number of control panel enhancement s has further simplified operation. Large, LED-backlit analog meters provide at-a-glance monitoring of vital engine and generator parameters, while a full diagnostic display alerts the operator of fault conditions. A dual scale ammeter provides read-outs on the smallest current changes. The G125 is equipped with the industry’s only VSS protection scheme or the voltage selector switch- if the VSS door is opened, the machine shuts down completely.

Operator safety is Doosan Portable Power’s primary concern. The G125 features many new and enhanced operator safety features that serve to protect the operator. A redesigned connection panel allows ample space for each connection, each terminal able to accept up to 2x500 MCM bare wire cables and multiple terminated cables simultaneously. An optional camlock panel expands connection capability via multiple 400A color-coded camlocks. An optional Roda Deaco engine overspeed shutoff system provides peace of mind in applications where combustible gas, vapors, or vapor dust are present- preventing engine runaway and helping ensure operator and jobsite safety.
