Heavy-Duty 120kW Power – Built for the Toughest Job Sites

When you’re working on a construction site, power outages aren’t just an inconvenience—they halt progress, delay deadlines, and cost money. You need a generator that delivers reliable, heavy-duty power in the harshest conditions. The EMEAN EM-W165 provides a solid 120kW (150kVA) of prime power, backed by a 138kW WEICHAI WP6D152E200 turbocharged and intercooled diesel engine. With its rugged construction, soundproof canopy, and robust 24V electric starting system, this is the kind of construction generators solution that keeps your tools running, your lights on, and your project moving forward—no matter what.

The EM-W165 is more than just another construction generators unit—it is a purpose-built power system engineered to withstand the demands of job site environments. With a standby rating of 132kW (165kVA), this unit provides ample headroom for starting heavy equipment with high inrush currents and handling sudden load surges. The generator operates at 1500 RPM (50Hz) with a fuel consumption of just 198.7 g/kW.h, making it a cost-effective construction generators choice for extended projects.

Powered by WEICHAI – The 6.75L Straight-Six Workhorse

At the heart of this construction generators powerhouse lies the WEICHAI WP6D152E200, a 6-cylinder, 6.75-liter turbocharged and intercooled diesel engine with an inline configuration. With a bore and stroke of 105×130 mm and a compression ratio of 18:1, this larger-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 1636 kPa and a mean piston speed of 6.5 m/s—a well-balanced figure that promotes long engine life while delivering robust power for demanding construction applications【1†L3-L6】.

The engine features a mechanical fuel pump system with electronic speed governor for precise frequency control, ensuring stable power output even under varying load conditions. The intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 139.3°C down to just 48.8°C, with minimal pressure drop【1†L1-L10】. The engine draws 615 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions【1†L4-L5】.

What truly sets this engine apart for construction generators applications is its remarkable oil consumption ratio of just ≤0.2% of fuel consumption—significantly lower than the industry average. With an oil capacity of 16L, the EM-W165 is designed for extended service intervals that minimize downtime on the job site【1†L1-L8】. The engine maintains oil pressure between 300–600 kPa at rated speed, with a low-pressure alarm and shutdown at 80 kPa to protect the engine from damage【1†L7-L8】.

Built to Start in the Harshest Conditions – When You Need It Most

Construction sites don’t shut down for cold weather, and neither should your generator. The WP6D152E200 starts reliably down to -10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -30°C【1†L1-L3】. This exceptional cold-start capability makes the EM-W165 a practical choice for construction projects across North America and Europe, where winter conditions can pose significant challenges for diesel equipment.

The 24V starting circuit is engineered with a maximum resistance of just 4 mΩ and uses 50 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions【1†L9-L13】. A 6kW starter motor and 35A battery charging alternator provide robust starting power that you can count on every time【1†L9-L11】. When the temperature drops and other equipment fails to start, this construction generators solution delivers the reliable starting performance you need to keep your project on schedule.
