Heavy-Duty 450kW Industrial Power – Engineered for Mission-Critical Reliability

When your industrial operations can’t afford a moment of downtime, you need a generator that delivers uncompromising power and unwavering reliability. The EMEAN EM-W619 provides a solid 450kW (563kVA) of prime power, backed by a 520kW WEICHAI 6M33D572E200 turbocharged and aftercooled diesel engine. Whether you’re powering a manufacturing plant, a mining operation, a data center, or a large commercial facility, this is the generator industrial solution that keeps your critical systems running when you need them most.

The EM-W619 is more than just another generator industrial—it is a purpose-built power system engineered to withstand the demands of heavy industrial environments. With a standby rating of 495kW (619kVA), this unit provides ample headroom for starting heavy equipment with high inrush currents and handling sudden load surges. The generator operates at 1500 RPM (50Hz) with a fuel consumption of just 198.3 g/kW.h, making it a cost-effective generator industrial choice for extended backup power.

Powered by WEICHAI – The 19.6L Straight-Six Workhorse

At the heart of this generator industrial lies the WEICHAI 6M33D572E200, a 6-cylinder, 19.6-liter turbocharged and aftercooled diesel engine with an inline configuration. With a bore and stroke of 150×185 mm and a compression ratio of 15:1, this massive-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 2.12 MPa and a mean piston speed of 9.25 m/s—demonstrating outstanding power density and combustion efficiency.

The engine features a mechanical fuel pump system and draws 2,752 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions. The intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 190.0°C down to just 58.1°C, with efficient charge-air cooling that enables higher power output, cleaner combustion, and more stable operation.

What truly sets this engine apart for generator industrial applications is its robust oil capacity of 36L (low) to 61L (high) with an oil consumption ratio of just 0.3% of fuel consumption. The engine maintains oil pressure between 400–650 kPa at rated speed, with low-pressure protection at 200 kPa to safeguard the engine from damage.

Built to Start in the Toughest Conditions

A generator industrial is only as good as its ability to start when you need it most. The 6M33D572E200 starts reliably down to -5°C without auxiliary starting devices, and with a preheater, it operates confidently down to -10°C. This cold-start capability makes the EM-W619 a practical choice for installations across North America and Europe, where winter storms can knock out the power grid for days.

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 a maximum resistance of just 8 mΩ and uses 70 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions.

Engineered for Quiet, Efficient Operation

The EM-W619 features a soundproof canopy lined with sound-reducing foam, making it a generator industrial that respects both industrial and urban environments. The industrial silencer and modular ventilation design further reduce noise levels, while all-metal canopy parts are powder-coated for durability and corrosion resistance.

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 that begins opening at 80°C and reaches full opening at 92°C. Coolant flow is 42.9 m³/h, and the system holds 43.93L of coolant. At rated conditions, total heat dissipation reaches 1,216.9 kJ/s, with the cooling system removing 156.9 kJ/s of heat while the exhaust carries away 411.2 kJ/s—ensuring stable operating temperatures even during extended run times.

Complete Generator Set Features

The EM-W619 generator set is built around the WEICHAI engine and features a VG-354ES brushless alternator with Class H insulation 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.

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

Industrial silencer for silent-type generator sets

5mm thickened bent chassis with double-layer anti-corrosion painting
