Heavy-Duty 300kW Power – Engineered for Commercial Emergency Applications

When the grid goes down and your business operations can’t afford a moment of downtime, you need a generator that delivers serious power with unwavering reliability. The EMEAN EM-W413 provides a solid 300kW (375kVA) of prime power, backed by a 353kW WEICHAI WP12D353E200 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 protecting a manufacturing plant, a data center, a hospital, or a commercial facility, this is the commercial emergency generator solution that keeps your critical systems running when you need them most.

The EM-W413 is more than just another commercial emergency generator—it is a purpose-built power system engineered to withstand the demands of industrial and commercial environments. With a standby rating of 330kW (413kVA), 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 210 g/kW.h, making it a cost-effective commercial emergency generator choice for extended backup power.

Powered by WEICHAI – The 11.596L Straight-Six Workhorse

At the heart of this commercial emergency generator lies the WEICHAI WP12D353E200, a 6-cylinder, 11.596-liter turbocharged and aftercooled diesel engine with an inline configuration. With a bore and stroke of 126×155 mm and a compression ratio of 16:1, this large-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 1.987 MPa and a mean piston speed of 7.75 m/s—a well-balanced figure that promotes long engine life while delivering robust power for demanding applications.

The engine features a mechanical fuel pump system and draws 1,522 kg/h of air at standby conditions, ensuring complete combustion and reduced emissions. The intercooling system is particularly impressive: at rated conditions, the intercooler maintains intake air temperature at just 55°C above ambient, with a maximum pressure drop of only 12 kPa, enabling higher power output, cleaner combustion, and more stable operation.

What truly sets this engine apart for commercial emergency 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 24L, the EM-W413 is designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 380–580 kPa at rated speed, with low-pressure protection at 80 kPa (alarm) and 40 kPa (shutdown) to safeguard the engine from damage.

Engineered for Quiet, Efficient Operation

The EM-W413 features a soundproof canopy lined with sound-reducing foam, making it a commercial emergency generator that respects both urban and suburban environments. The industrial silencer and modular ventilation design further reduce noise levels, while the all-metal canopy parts are powder-coated for durability and corrosion resistance.

The engine’s thermal management is equally impressive. The closed-loop water cooling system is rated for operation up to 50°C ambient temperature, with a thermostat that begins opening at 71°C and reaches full opening at 80°C. Coolant flow is substantial, and the system holds 25L of coolant. At overload conditions, the cooling system removes 135.9 kJ/s of heat while the exhaust carries away 278.6 kJ/s, with total engine heat output managed efficiently—ensuring stable operating temperatures even during extended run times.

Built to Start in the Toughest Conditions

A commercial emergency generator is only as good as its ability to start when you need it most. The WP12D353E200 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-W413 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: an 8.5kW starter motor and 55A battery charging alternator provide ample starting power that you can count on every time. When a winter storm hits, this commercial emergency generator delivers the reliable starting performance you need to keep your facility running.
