MEE 2019: Cummins debuts natural gas generator for region

New HSK78G produces up to 2MW of power for prime and peaking power applications

Global engines and power major Cummins has launched its new HSK78G natural gas generator at the Middle East Electricity show, targeting the product at prime and peaking power requirements in sectors ranging from mining to medical applications.

The HSK78G has a 78L engine providing a power density of up to 2.0MW and is available in both 50Hz and 60Hz variants. According to Cummins, the generator series is designed to provide “reliable power, regardless of the natural gas source or the climate”, including heat conditions of up to 55-degrees Celsius and extreme altitudes.

According to a statement by the manufacturer: “Fuelling the next generation of power, the (new model) offers a total package of gas generator capabilities and innovative gas technology for prime and peaking power applications. This new technology represents a bold step into the gas arena for Cummins that pushes new levels of efficiency, transient performance and gas variation well beyond former natural gas generators.”

Craig Wilkins, director of Cummins Prime Power Segment and Global Sales Support, said: “The HSK78G models are suitable for a diverse set of industries from mining and manufacturing to shopping malls and hospitals. The new generator series has been designed to push the boundaries of performance to extremes while achieving a low total cost of ownership. A high electrical efficiency of up to 44.2% (50Hz) and 43.5% (60Hz) is achieved on a wide range of pipeline natural gas down to 70 methane number (MN) without impacting power output and efficiency.

“In addition, the barrier-breaking fuel flexibility of the HSK78G enables the utilisation of low-cost, low-BTU and free fuel sources, that would otherwise be considered waste products, delivering robust power even with very aggressive fuels with minimal derating.”
