This portable generator provides the factory-installed, dual-fuel option which allows power customers to substantially reduce costs and meet changing fuel availability by utilizing a wide range of gaseous fuels. Designed for use with the 50 Hz XQ2000 power module driven by the Cat 3516B engine, the DGB advanced control system automatically adjusts to changes in incoming fuel quality and pressure. This allows the engine to run on a wide variety of fuels, from associated gas to vaporized LNG, with no loss of performance integrity, which makes it an ideal generator rental unit. It maintains diesel performance levels with up to 70 percent replacement of diesel with gas, and accepts up to 55 percent inerts. No customer input or gas analysis is needed during operation, and no recalibration is required when the equipment is moved or the gas supply changes.
