Heavy-Duty 24kW Power – Engineered for Reliability and Efficiency

When the grid goes down, you need a generator that delivers consistent, dependable power without compromise. The EMEAN EM-W33 provides a robust 24kW (30kVA) of prime power, backed by a 30kW WEICHAI WP2.3D33E200 turbocharged diesel engine. Whether you are protecting your home, farm, or small business from unexpected outages, this 240 vac generator is built to keep your essential systems running smoothly.

The EM-W33 is more than just another entry in the 240 vac generator market—it is a thoughtfully engineered power system that combines proven turbo diesel technology with modern control features and quiet operation. With a standby rating of 26.4kW (33kVA), 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 7.94 L/h at full load, making it one of the most fuel-efficient options in its power class.

Powered by WEICHAI – Turbocharged Performance You Can Trust

At the heart of this 240 vac generator lies the WEICHAI WP2.3D33E200, a 4-cylinder, 2.3-liter turbocharged diesel engine with an L-type cylinder arrangement and a compression ratio of 17.5:1. Unlike naturally aspirated engines in this category, the turbocharged configuration delivers significantly higher power density and superior performance at altitude. The engine produces 30kW of gross output, providing ample headroom for the generator’s 24kW rated output.

The engine’s mean effective pressure of 1.15 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 WP2.3D33E200 delivers impressive efficiency. At 7.94 L/h at full load, this translates to approximately 252 g/kWh—highly competitive for a turbocharged diesel in this power range. Over a year of intermittent or standby operation, this efficiency directly translates to lower operating costs and less frequent refueling.

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-W33 is designed for extended service intervals that minimize downtime and maximize productivity.

Built to Start in Any Weather – Cold Climate Ready

Cold weather reliability sets this generator apart from many competitors. The WP2.3D33E200 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-W33 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.

Thermal Management – Engineered for Continuous Operation

The WP2.3D33E200’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 3.4 m³/h at rated conditions.

Heat balance data reveals the engine’s efficient thermal design: at rated working conditions, the cooling system removes 16.8 kJ/s of heat, while the exhaust carries away 19.1 kJ/s. Total engine heat output is 75.7 kJ/s, with surface radiation accounting for just 5%—a testament to the effective heat dissipation through the cooling and exhaust systems.
