US-based Cummins has launched an upgraded 60 Hz natural gas generator set as part of its 91-litre gas product range.
The new model series, powered by an 18-cylinder multi-turbo natural gas engine, offers higher power up to 2,000 kW at low emissions down to 0.5g/hp-h NOx without after treatment— in addition to meeting the transient requirements of ISO 8528-5 G1.
The QSV91 (pictured) gas series can function in continuous and standby power mode at 60 Hz through the use of a single generator set rated 1.54 MWe to 2 MWe, Cummins said. “These features will make it a preferred choice for isolated locations and off-grid applications, indeed anywhere a rugged and robust power solution is needed.”
According to Cummins, QSV91 series minimises voltage, frequency deviation and operational time-to-recover as well as achieving 100% load shed without shutdown.
“The new series has been developed to function in extreme environments and is capable of operating in ambient temperatures of up to 131°F and at 4,921 feet above sea level,” Cummins said.
Peter Schroeck, general sales manager for Cummins North and Central America, said QSV91’s “multi-turbo design provides optimal transient response as well as high altitude and ambient temperature capability”.
