200kW Quiet Diesel Generator – Weichai Powered | EMEAN Power

The 200kW quiet diesel generator powered by the Weichai WP10D264E201 engine delivers industrial-grade prime and standby power for residential estates, commercial buildings, hospitals, data centers, and noise-sensitive construction sites. Rated at 250 kVA / 200 kW prime and 275 kVA / 220 kW standby, this 60 Hz (1800 RPM) unit pairs Weichai‘s proven heavy-duty diesel platform with a sound-attenuated enclosure that makes it a genuinely quiet generator solution for environments where noise restrictions are non-negotiable.

The WP10D264E201 is a 6-cylinder, 9.726-liter in-line turbocharged and aftercooled diesel engine with a 126×130 mm bore/stroke and 17:1 compression ratio. Its mechanical fuel pump system delivers reliable performance without the complexity of electronic controls, making field service straightforward even in remote locations.

Why This Quiet Generator Stands Apart

For property managers, facility engineers, and business owners evaluating quiet generator options that must comply with strict local noise ordinances, the EMEAN‑powered EM‑W275 set delivers on multiple fronts:

Sound-Attenuated Enclosure – The generator is housed in a powder-coated steel canopy lined with sound-reducing acoustic foam. An industrial-grade silencer further reduces exhaust noise, while anti-vibration pads on the steel chassis isolate structure-borne noise. This multi-layered approach transforms what would be a 100+ dB open-frame unit into a generator quiet enough for residential neighborhoods and urban job sites.

Proven Heavy-Duty Engine Architecture – The 9.726-liter displacement delivers substantial low-end torque with fuel consumption as low as 197.7 g/kW·h. The 24-volt electrical system with 8.5 kW starter and 55 A alternator ensures reliable starting down to -10°C without auxiliary devices, and -30°C with preheating.

Exceptional Thermal Management – Heat-balance testing at 32.0°C ambient shows the cooling system removes 94.9 kJ/s of heat at rated load, while the intercooler drops charge-air temperature from 146.4°C to just 57.4°C. The engine is designed for operation up to 50°C ambient, with a cooling system holding 50 kPa minimum pressure and 22 liters of coolant capacity. This thermal efficiency ensures your quiet generator maintains consistent performance even during extended outages.

Low Maintenance Design – Oil capacity of 24 liters with pressure maintained between 330‑550 kPa at rated speeds, and an oil‑to‑fuel consumption ratio of ≤0.2%, means fewer top‑ups and less waste oil disposal between service intervals.

Performance Highlights from the Engine Datasheet

The WP10D264E201 datasheet reveals engineering refinements that set this model apart:

Mean effective pressure of 1.645 MPa and a piston speed of 7.8 m/s indicate a highly tuned yet conservative state of tune, balancing power with longevity.

The intercooler pressure drop is limited to 12 kPa, and maximum exhaust backpressure is held to 6±0.5 kPa, allowing straightforward exhaust system design.

Lubrication flow of 118 L/min ensures full film protection even under sustained high loads.

The ignition order (1‑5‑3‑6‑2‑4) provides balanced firing impulses that reduce torsional vibration, and the 136‑tooth flywheel ring gear guarantees smooth cranking and stable idle at 650±50 r/min.

These specifications translate into a generator quiet enough for noise-sensitive applications, yet powerful enough to handle full facility loads with confidence.

Ideal Applications

This power class is perfectly suited for:

Residential estates and gated communities – where nighttime noise restrictions are strictly enforced

Hospitals and healthcare facilities – requiring immediate backup for life-safety equipment

Data centers – where uninterrupted operation is non‑negotiable

Commercial high‑rises – ensuring elevator, lighting, and HVAC systems remain online

Urban construction sites – providing reliable power without disturbing neighboring businesses
