Heavy-Duty 64kW Backup – Your Ultimate Protection Against Power Outages

When the lights go out and the grid fails, you need a generator that delivers serious power without compromise. The EMEAN EM-W88 provides a solid 64kW (80kVA) of prime power, backed by a 72kW WEICHAI WP4.1D80E200 turbocharged diesel engine. Whether you are protecting a large home, a farm, a retail store, or a small business, this is the generator for blackout situations that keeps your critical systems running when the grid fails.

The EM-W88 is more than just another generator for blackout protection—it is a thoughtfully engineered power system that combines proven WEICHAI diesel technology with modern control features and a soundproof canopy for quiet operation. With a standby rating of 70.4kW (88kVA), 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 full-load fuel consumption of 19.91 L/h, making it a practical choice for extended blackout events.

Powered by WEICHAI – The 4.087L Workhorse

At the heart of this generator for blackout protection lies the WEICHAI WP4.1D80E200, a 4-cylinder, 4.087-liter turbocharged diesel engine with an L-type cylinder arrangement. With a bore and stroke of 105×118 mm and a compression ratio of 17.5, this larger-displacement platform delivers exceptional torque and thermal efficiency【4†L4-L6】. The engine achieves a mean effective pressure of 1.409 MPa and a mean piston speed of 5.9 m/s—a conservative figure that promotes long engine life by reducing wear on cylinder walls and piston rings【8†L2-L4】.

What truly sets this engine apart is its remarkable oil consumption ratio of just 0.1% of fuel consumption, significantly lower than the industry average【6†L12-L13】. With an oil capacity of 12L (low) to 14L (high), the EM-W88 is designed for extended service intervals that minimize downtime during critical blackout periods. The engine maintains oil pressure between 300–500 kPa at rated speed, with a low-pressure alarm at 100 kPa to protect the engine from damage【6†L8-L11】.

Built to Start in the Coldest Conditions – When You Need It Most

A generator for blackout is only useful if it starts when you need it. The WP4.1D80E200 starts reliably down to -15°C without auxiliary starting devices, and with a preheater, it operates confidently down to -25°C【5†L2-L4】. This exceptional cold-start capability makes the EM-W88 a practical choice for installations across North America and Europe, where winter blackouts can pose significant challenges for diesel equipment.

The 24V 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【7†L3-L4】. A 4.5kW starter motor and 55A battery charging alternator provide robust starting power that you can count on every time【6†L17-L18】. When a winter storm knocks out the power grid, this generator for blackout delivers the reliable starting performance you need to keep your family or business running.

Engineered for Quiet, Efficient Operation

The EM-W88 features a soundproof canopy lined with sound-reducing foam, making it a generator for blackout that respects both residential and commercial 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. With a sound power level of just 105.6 dB(A)—remarkably low for a 64kW diesel unit—the EM-W88 delivers the kind of neighborhood-friendly operation that makes it an ideal choice for residential backup【6†L16】.

The engine’s thermal management is equally impressive. The closed-loop water cooling system is rated for operation up to 40°C ambient temperature, with a thermostat that begins opening at 76°C and reaches full opening at 89°C【5†L8-L10】. Coolant flow is 6.2 m³/h, and the system holds 9.4L of coolant【7†L8】【5†L12】. At rated conditions, the cooling system removes 31.2 kJ/s of heat while the exhaust carries away 56.8 kJ/s, ensuring stable operating temperatures even during extended run times【7†L17-L18】.

Clean, Efficient Combustion

The turbocharged WP4.1D80E200 draws 325 kg/h of air at rated conditions and 339 kg/h at standby, ensuring complete combustion and reduced emissions【5†L6】. The exhaust system is designed with a maximum back pressure limit of 10 kPa, allowing for flexible exhaust routing without compromising performance【5†L14】. Maximum exhaust temperature is capped at 560°C—significantly lower than many competitors—indicating robust thermal design that protects turbocharger components over the long term【5†L15-L16】.
