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 418kW WEICHAI WP13D460E311 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 electric generator industrial solution that keeps your critical systems running when you need them most.

The EM-W481 is more than just another electric generator industrial—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 1800 RPM (60Hz) with a fuel consumption of just 195g/kW.h, making it a cost-effective electric generator industrial choice for extended backup power.

Powered by WEICHAI – The 12.54L Common-Rail Powerhouse

At the heart of this electric generator industrial lies the WEICHAI WP13D460E311, 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 15:1, 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 intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 204.6°C down to just 54.7°C, with efficient charge-air cooling that enables higher power output, cleaner combustion, and more stable operation. The engine draws 2,128 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions.

What truly sets this engine apart for electric generator industrial 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 low-pressure protection at 120 kPa to safeguard the engine from damage.

Advanced Common-Rail Technology – Superior Performance and Efficiency

The WP13D460E311 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 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

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 achieves a mean effective pressure of 2.445 MPa and a mean piston speed of 9.9 m/s—demonstrating outstanding power density and combustion efficiency.

Built to Start in the Toughest Conditions

An electric generator industrial is only as good as its ability to start when you need it most. The WP13D460E311 starts reliably down to -10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -30°C. 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 70A battery charging alternator provide ample starting power that you can count on every time. The starting circuit features a maximum resistance of just 20 mΩ and uses 70 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions. When a winter storm hits, this electric generator industrial delivers the reliable starting performance you need to keep your facility running.

Engineered for Quiet, Efficient Operation

The EM-W481 features a soundproof canopy lined with sound-reducing foam, making it an electric generator industrial that respects both industrial and urban environments. The industrial silencer and modular ventilation design further reduce noise levels, while all-metal canopy parts are powder-coated for durability and corrosion resistance. With a noise level of just 108.9 dB(A) (acoustic power level)—remarkably low for a 350kW diesel unit—the EM-W481 delivers the kind of operation that makes it suitable for installations in noise-sensitive areas.

The engine's thermal management is equally impressive. The closed-loop water cooling system is rated for operation up to 45°C ambient temperature, with a thermostat that begins opening at 76°C and reaches full opening at 88°C. Coolant flow is 29.6 m³/h, and the system holds 25L of coolant. At rated conditions, the cooling system removes 155.1 kJ/s of heat while the exhaust carries away 286.6 kJ/s, with total engine heat output of 1000 kJ/s—ensuring stable operating temperatures even during extended run times.
