Heavy-Duty 800kW Standby Power – Engineered for Mission-Critical Reliability

When the grid goes down and your operations can‘t afford a moment of downtime, you need a generator that delivers uncompromising power and unwavering reliability. The EMEAN EM-W1100 provides a solid 800kW (1000kVA) of prime power, backed by a 910kW WEICHAI 8M33D1012E311 turbocharged and intercooled diesel engine. Whether you’re protecting a hospital, a data center, a manufacturing plant, or a large commercial facility, this is the standby emergency generator solution that keeps your critical systems running when you need them most.

The EM-W1100 is more than just another standby emergency generator—it is a purpose-built power system engineered to withstand the demands of heavy industrial and commercial environments. With a standby rating of 880kW (1100kVA), this standby emergency generator provides ample headroom for starting heavy equipment with high inrush currents and handling sudden load surges. The generator operates at 1800 RPM (60Hz) with a fuel consumption of just 206 g/kW.h, making it a cost-effective choice for extended backup power.

Powered by WEICHAI – The 26.14L V8 Powerhouse

At the heart of this standby emergency generator lies the WEICHAI 8M33D1012E311, a V-type 8-cylinder, 26.14-liter turbocharged and intercooled diesel engine. With a bore and stroke of 150×185 mm and a compression ratio of 15:1, this massive-displacement V8 platform delivers exceptional torque and thermal efficiency for the most demanding applications.

The engine features an advanced electronically controlled high-pressure common-rail fuel injection system, representing the latest generation of diesel engine technology. Unlike traditional mechanical pump systems, common-rail technology delivers fuel at extremely high pressures directly to the injectors, ensuring precise metering and atomization for each cylinder. This results in:

Lower fuel consumption – Optimized combustion efficiency reduces fuel waste

Reduced emissions – Cleaner, more complete combustion

Quieter operation – Smoother, more controlled combustion reduces engine noise

Better cold-start performance – High-pressure fuel delivery ensures reliable ignition in cold conditions

The engine draws substantial air at rated conditions, ensuring complete combustion and reduced emissions. The advanced intercooling system efficiently reduces intake air temperatures, enabling higher power output, cleaner combustion, and more stable operation even under heavy load.

Built to Start When You Need It Most

A standby emergency generator is only as good as its ability to start when you need it most. The 8M33D1012E311 starts reliably down to -10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -20°C. This cold-start capability makes the EM-W1100 a practical choice for installations across North America and Europe, where winter storms can knock out the power grid for days. With no power loss at 1000 meters in plateau and lossless output power at 45°C, this engine is engineered for performance in challenging environments.

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. The starting circuit features low resistance and uses 70 mm² wiring, with a 24V/196A heating grille for extreme cold conditions—ensuring reliable starts even in the harshest environments.

Engineered for Durability and Efficiency

The 8M33 series is built on WEICHAI‘s high-end M33 platform, delivering class-leading efficiency through high combustion and high-pressure ratio turbochargers. The engine’s robust construction ensures long service life and minimal maintenance requirements.

What truly sets this engine apart is its substantial oil capacity of 90L (low) to 105L (high), designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 400–650 kPa at rated speed, with low-pressure protection to safeguard the engine from damage.

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 designed for optimal temperature control. The system holds substantial coolant capacity—ensuring stable operating temperatures even during extended run times. At rated conditions, total heat dissipation is efficiently managed, with the cooling system and exhaust system working in concert to maintain optimal operating temperatures.

Complete Generator Set Features

The EM-W1100 generator set is built around the WEICHAI engine and features a VG-404D brushless alternator with Class H insulation and IP23 protection. The alternator is available from leading brands including Stamford, Leroy-Somer, or Marathon, giving businesses 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.

Key features of the complete generator set include:

Base frame fuel tank with customizable capacity for 8–10 hours of continuous runtime

Digital control panel with automatic protection and monitoring

Soundproof canopy lined with sound-reducing foam for quiet operation

MCCB air circuit breaker for overcurrent shutdown protection
