Heavy-Duty 350kW Power – Engineered for Demanding Industrial Environments

When your industrial operations can’t afford a moment of downtime, you need a generator that delivers uncompromising power and reliability. The EMEAN EM-W481 provides a solid 350kW (438kVA) of prime power, backed by a 392kW WEICHAI WP13D440E310 turbocharged and aftercooled diesel engine. With a wide voltage range from 110V to 660V and single or three-phase configurations available, this generator adapts to your specific electrical needs. Whether you’re powering a manufacturing plant, a mining operation, a data center, or a large commercial facility, this is the industrial electric generator solution that keeps your critical systems running when you need them most.

The EM-W481 is more than just another industrial electric generator—it is a purpose-built power system engineered to withstand the demands of heavy industrial and commercial environments. With a standby rating of 385kW (481kVA), 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 197.5 g/kW.h, making it a cost-effective industrial electric generator choice for extended backup power.

Powered by WEICHAI – The 12.54L Common-Rail Powerhouse

At the heart of this industrial electric generator lies the WEICHAI WP13D440E310, a 6-cylinder, 12.54-liter turbocharged and aftercooled diesel engine with an inline configuration. With a bore and stroke of 127×165 mm and a compression ratio of 16:1, this large-displacement platform delivers exceptional torque and thermal efficiency. The engine features an advanced common-rail fuel injection system—a significant upgrade over traditional mechanical pump systems—providing precise fuel delivery, cleaner combustion, and improved fuel economy. The engine achieves a mean effective pressure of 2.81 MPa—remarkably high for this displacement class—demonstrating outstanding power density and combustion efficiency.

The intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 192.8°C down to just 50.3°C, with a maximum pressure drop of only 2 kPa. This efficient charge-air cooling enables higher power output, cleaner combustion, and more stable operation. The engine draws 1,887 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions.

What truly sets this engine apart for industrial electric generator 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 30L, the EM-W481 is designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 350–550 kPa at rated speed, with dual low-pressure protection at 120 kPa (alarm) and 80 kPa (shutdown) to safeguard the engine from damage.

Advanced Common-Rail Technology – Superior Performance and Efficiency

The WP13D440E310 is equipped with a common-rail fuel system, representing the latest generation of diesel engine technology. Unlike traditional mechanical pump systems, common-rail technology delivers fuel at extremely high pressures—up to 1,800 bar—directly to the injectors, ensuring precise metering and atomization for each cylinder. This results in:

Lower fuel consumption – Optimized combustion efficiency reduces fuel waste

Reduced emissions – Cleaner, more complete combustion meets stringent environmental standards

Quieter operation – Smoother, more controlled combustion reduces engine noise

Better cold-start performance – High-pressure fuel delivery ensures reliable ignition in cold conditions

The engine meets China Non-Road China III emission standards, demonstrating a commitment to environmental responsibility without compromising power output.

Built to Start in the Toughest Conditions

An industrial electric generator is only as good as its ability to start when you need it most. The WP13D440E310 starts reliably down to -10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -35°C—one of the lowest cold-start temperatures available in this power class. This exceptional cold-start capability makes the EM-W481 a practical choice for installations across North America and Europe, where winter storms can knock out the power grid for days.

The 24V starting circuit is engineered with robust components: a 7.5kW starter motor and 55A battery charging alternator provide ample starting power that you can count on every time. The starting circuit features a maximum resistance of just 0.04 Ω and uses 70 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions. When a winter storm hits, this industrial electric generator delivers the reliable starting performance you need to keep your facility running.
