Doosan Portable Power’s G125 T4i is one of the most autonomous and maintenance-free T4i generators in the market. The G125 uses a maintenance-free Diesel Oxidation Catalyst intead of a Diesal Particulate Filter – this means that there is NO regeneration. With 25-hours of on-board fuel (at 100% load), the G125 can run with longer service intervals.
To boast, the G125 is a dynamic machine that can go over any terrain and meet nearly every electrical requirement. Doosan Portable Power’s legacy rugged running gear and hardened enclosure stand up to harsh environments. And, with the ability for the generator to change from 50Hz to 60Hz, the G125 is one of the markets most versatile generators.
The G125 Tier-4i generator from Doosan Portable Power delivers 128 kVA (102 kW) at 67 dB(A) at 100% load with an optional variable speed fan, Doosan Portable Power delivers the coolest and quietest mid-range T4i package in the market. To increase the versatility of the machine, a Dual-Frequency switch is a standard feature that allows the generator to change from 50Hz to 60Hz. Enhancing performance in even the most extreme temperatures is an optional Tundra Package, which ensures startup and reliable operation in temperatures as low as -40°F/°C. The package includes a coolant heater, oil pan heater, battery charger, battery heater pad and heated breather hose.
A fuel-efficient Tier 4i-compliant Cummins QSB5 engine improves fuel economy and lowers maintenance of the G125 T4i. At 100% load, the G125 T4i can run for 25 hours. To keep the machine up and running, the Cummins engine uses a maintenance-free Diesel Oxidation Catalyst to clean the emissions. The G125 T4i is equipped with Leroy-Somer alternators with AREP excitation, protecting against overload and short-circuit, offering voltage stability and greater motor-starting capability.
Operation has been simplified with a number of control panel enhancements. Large, LED-backlit analog meters provide at-a-glance monitoring of vital engine and generator parameters, while a full diagnostic display alerts operators of fault conditions. A dual scale ammeter provides read-outs on even the smallest current changes, while the voltage selector switch is equipped with the industry’s only VSS protection scheme – guarding against an operator switching voltage during machine use – if the VSS door is opened, the machine shuts down completely.
Operator safety is enhanced with a redesigned connection panel that allows plenty of room for connection. Each terminal can simultaneously accept up to 2×500 MCM bare wire cables and multiple terminated cables; 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.
