The Doosan G25WDO-3A-T4F is a towable diesel generator built for mobile power applications where clean operation, flexible voltage options, and easy transport matter. This unit has 0 hours and delivers 20kW of prime power, or 25 kVA, making it a practical choice for smaller commercial, construction, industrial, and temporary power needs. At its core is a Doosan D18 engine with a 1.8L three-cylinder turbocharged and intercooled diesel configuration. The engine produces 33.5 HP, with an output of 25 kWm at 1800 RPM. The generator supports both 50 Hz and 60 Hz operation, while its three-position voltage selector provides added flexibility for different electrical requirements.

The G25WDO-3A-T4F also uses a Marelli Motori brushless alternator with 12 leads and ±1% voltage regulation. Its EPA Tier 4 Final emissions system uses a diesel oxidation catalyst and does not require a DPF or DEF. With a 46.7-gallon fuel tank and approximately 25.9 hours of runtime at full load, this Doosan is well suited for extended temporary power assignments.
