Reliable 30kW Power – Ready for 240V Applications

When the grid goes down, you need a generator that delivers consistent, dependable power—and if you‘re powering 240V appliances, tools, or equipment, you need the right configuration from the start. The EMEAN EM-W41 provides a solid 30kW (37.5kVA) of prime power, backed by a 36kW WEICHAI WP2.3D40E200 turbocharged diesel engine. With voltage options including 415/240V, 380/220V, and 400/230V, this is a generator with 240v outlet capability built for North American and European standards.

The EM-W41 is more than just another generator with 240v outlet—it is a thoughtfully engineered power system that combines proven turbo diesel technology with modern control features. With a standby rating of 33kW (41.25kVA), this unit provides ample headroom for starting motors with high inrush currents and handling temporary load surges. The generator operates at 1500 RPM (50Hz) with a fuel consumption of just 8.5 L/h at full load, making it a practical choice for standby and prime power applications alike.

Powered by WEICHAI – Turbocharged Performance You Can Trust

At the heart of this generator with 240v outlet lies the WEICHAI WP2.3D40E200, a 4-cylinder, 2.3-liter turbocharged diesel engine with an L-type cylinder arrangement and a compression ratio of 17.5. The engine features a vertical, in-line, water-cooled, four-stroke design with intercooling, delivering 36kW of gross engine output with a 40kW standby capacity.

The engine’s mean effective pressure of 1.4 MPa is among the highest in its displacement class, indicating exceptional thermal efficiency and torque characteristics. Combined with a mean piston speed of just 4.6 m/s, this engine achieves an optimal balance between power delivery and long-term durability, reducing wear on cylinder walls and piston rings over thousands of operating hours.

Fuel Efficiency That Lowers Your Operating Costs

Fuel consumption is a critical consideration for any generator owner, and the WP2.3D40E200 delivers competitive efficiency. At 8.5 L/h at full load, this translates to predictable operating costs and less frequent refueling compared to many competitors in this power range. With a fuel consumption rate of approximately 238 g/kWh, the EM-W41 is designed to keep your fuel bills manageable.

The engine’s oil consumption ratio is remarkably low at just 0.4% of fuel consumption, meaning less frequent oil top-ups and lower maintenance costs. With an oil capacity of 5.3L (low) to 8L (high), the EM-W41 is designed for extended service intervals that minimize downtime and maximize productivity.

Built to Start in Any Weather

Cold weather reliability sets this generator apart from many competitors. The WP2.3D40E200 starts reliably down to -5°C without auxiliary starting devices, and with a preheater, it operates confidently down to -15°C. This capability makes the EM-W41 a practical choice for installations across North America and Europe, where winter temperatures can pose significant challenges for diesel equipment.

The electrical system features a 12V negative-ground configuration with a 3kW starter motor and a 35A battery charging alternator. The 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. DC24V electric start is also available.

Thermal Management – Engineered for Continuous Operation

The WP2.3D40E200‘s cooling system is designed for sustained performance even in demanding environments. The engine is rated for operation up to 40°C ambient temperature, with a thermostat that begins opening at 72°C and reaches full opening at 82°C. The closed-loop forced water cooling system maintains optimal thermal balance, with coolant flow of 3.8 m³/h at rated conditions.

Heat balance data reveals the engine’s efficient thermal design: at rated working conditions, the cooling system removes 21.5 kJ/s of heat, while the exhaust carries away 24.1 kJ/s. Total engine heat output is 93.3 kJ/s, with surface radiation accounting for just 5%—a testament to the effective heat dissipation through the cooling and exhaust systems.

Clean, Efficient Combustion

The turbocharged WP2.3D40E200 draws 152 kg/h of air at rated conditions and 159 kg/h at standby, ensuring complete combustion and reduced emissions. The exhaust system is designed with a maximum back pressure limit of 8 kPa, allowing for flexible exhaust routing without compromising performance. Maximum exhaust temperature is capped at 650°C, indicating robust thermal design that protects turbocharger components over the long term.

Complete Generator Set Features

The EM-W41 generator set is built around the WEICHAI engine and features a brushless alternator with Class H insulation, an automatic voltage regulator (AVR), and IP23 protection. The alternator is available from leading brands including Stamford, Leroy-Somer, or Marathon, giving customers flexibility in their specification. The digital control panel (Smartgen or Deep Sea) includes auto-protection features such as overcurrent shutdown and low oil pressure alarm.
