JENBACHER J620 GS Natural Gas Engine – 3431 kW, 50 Hz, Inline 12-Cylinder - 2014

The JENBACHER J620 GS is a high-output, industrial-grade natural gas engine designed for continuous-duty power generation and combined heat and power (CHP) systems. Manufactured in 2014, this 12-cylinder inline engine delivers 3431 kW of electrical power at 50 Hz and 1500 RPM, making it suitable for use in industrial facilities, district heating plants, and utility-scale installations.

This unit has clocked approximately 71,000 operating hours and is currently in a partially dismantled state, likely for transport, maintenance, or upgrade purposes. Importantly, it comes equipped with a brand-new alternator, offering extended operational life and improved efficiency. The engine features a water-cooled, closed-loop cooling system, forced lubrication with oil cooler, and advanced combustion optimization to ensure high performance and durability.

Electrical efficiency ranges from 42% to 44%, with low NOx emissions (<250 mg/Nm³) and excellent fuel economy of 0.31–0.33 m³/kWh. The unit is CHP-compatible and offers exhaust heat recovery potential with an exhaust gas temperature of ~450–550°C and exhaust flow of 15,000–18,000 Nm³/h.

This engine is ideal for applications where electricity and thermal energy are both needed, as well as for utility grid support or backup generation in large-scale facilities. Currently located in Asia, this engine is available for immediate inspection and relocation.
