Heavy-Duty 100kW Backup Power – Engineered for Instant Electric Starting

When the grid goes down and you need serious backup power, the EMEAN EM-W138 delivers a solid 100kW (125kVA) of prime power, backed by a 132kW WEICHAI WP6D132E200 turbocharged and intercooled diesel engine. With a wide voltage range from 110V to 660V and single or three-phase configurations available, this generator adapts to your specific electrical needs. And with its advanced 24V electric starting system featuring a 6kW starter motor and 35A battery charging alternator, this is a generators electric start solution that fires up the moment you need it—no pull cords, no frustration, just instant power on demand.

The EM-W138 is more than just another generators electric start unit—it is a thoughtfully engineered power system that combines proven WEICHAI diesel technology with intelligent control features and a soundproof canopy for quiet operation. With a standby rating of 110kW (138kVA), 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 208.8 g/kW.h, making it a cost-effective generators electric start choice for extended backup power.

Powered by WEICHAI – The 6.75L Straight-Six Powerhouse

At the heart of this generators electric start solution lies the WEICHAI WP6D132E200, a 6-cylinder, 6.75-liter turbocharged and intercooled diesel engine with an inline configuration. With a bore and stroke of 105×130 mm and a compression ratio of 18:1, this larger-displacement platform delivers exceptional torque and thermal efficiency. The engine achieves a mean effective pressure of 1423 kPa and a mean piston speed of 6.5 m/s—a well-balanced figure that promotes long engine life while delivering robust power.

The engine features an electronic speed governor for precise frequency control, ensuring stable power output even under varying load conditions. The intercooling system is particularly impressive: at rated conditions, the intercooler reduces intake air temperature from 118.8°C down to just 53.4°C, with minimal pressure drop. The engine draws 544 kg/h of air at rated conditions, ensuring complete combustion and reduced emissions.

What truly sets this engine apart is its remarkable oil consumption ratio of just 0.2% of fuel consumption—significantly lower than the industry average. With an oil capacity of 20L, the EM-W138 is designed for extended service intervals that minimize downtime. The engine maintains oil pressure between 300–600 kPa at rated speed, with a low-pressure alarm and shutdown at 120 kPa to protect the engine from damage.

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

A generators electric start system is only as good as its ability to start when you need it. The WP6D132E200 starts reliably down to -10°C without auxiliary starting devices, and with a preheater, it operates confidently down to -30°C. This exceptional cold-start capability makes the EM-W138 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 a maximum resistance of just 2 mΩ and uses 65-85 mm² wiring, ensuring ample current delivery to the starter even in the coldest conditions. A 6kW starter motor and 35A battery charging alternator provide robust starting power that you can count on every time. When a winter storm hits, this generators electric start system delivers the reliable starting performance you need to keep your family or business running.

Engineered for Quiet, Efficient Operation

The EM-W138 features a soundproof canopy lined with sound-reducing foam, making it a generators electric start solution 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. The engine noise is rated at ≤114 dB(A) (acoustic power level)—remarkably low for a 100kW diesel unit.

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 76°C and reaches full opening at 90°C. Coolant flow is 11.1 m³/h, and the system holds 8L of coolant. At rated conditions, the cooling system removes 52.6 kJ/s of heat while the exhaust carries away 77.9 kJ/s, ensuring stable operating temperatures even during extended run times.

Clean, Efficient Combustion

The turbocharged and intercooled WP6D132E200 draws 544 kg/h of air at rated conditions and 582 kg/h at standby, ensuring complete combustion and reduced emissions. The exhaust system is designed with a maximum back pressure limit of 6.5 kPa, allowing for flexible exhaust routing without compromising performance. Maximum exhaust temperature is capped at 700°C before the turbocharger and 550°C after—indicating robust thermal design that protects turbocharger components over the long term.

Complete Generator Set Features

The EM-W138 generator set is built around the WEICHAI engine and features a VG-274D brushless alternator with Class H insulation, an automatic voltage regulator (AVR), 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.
