The new units are certified to accept rated load in one step as specified by NFPA 110, making them suitable for use in emergency standby power applications.

Gaseous generator sets fill an important role in providing standby power at remote locations, either running on natural gas or on LP.

MTU Onsite Energy has introduced seven new gaseous-fueled generator sets in the important power node from 130 kW to 400 kW. The new units are certified to accept rated load in one step as specified by NFPA 110, a transient performance feature that makes them ideal for standby power applications where gaseous fuels are preferred. The new units are standby-rated at 130 kW, 150 kW, 175 kW, 200 kW, 260 kW, 325 kW and 400 kW when running on natural gas. Standby ratings are slightly lower when running on LP gas.

“Gaseous generator sets fill an important role in providing standby power at remote locations, either running on natural gas or on LP gas,” says Al Prosser, director of sales, MTU Onsite Energy. “They are also economical to run due to the lower cost of gaseous fuel, and they provide a high level of reliability due to superior design and performance testing. The MTU Onsite Energy distribution network insures years of reliable performance and after-sales support.”

The 130 kW and 150 kW units feature an 8.1 liter inline six-cylinder engine. The 175 kW and 200 kW units feature an 11.1 liter inline six-cylinder engine. The 260 kW unit has a 14.6 liter engine, the 325 kW unit has an 18.3 liter engine and the 400 kW unit has a 21.9 liter engine. All engines have turbochargers with charge-air cooling and EPA-certified three-way catalysts for emissions compliance. They also feature extra large oil sumps which aid in extending oil change intervals.

The units come standard with a UL-recognized digital control panel with an LCD display and complete system metering. The brushless, rotating-field alternators have a 300 percent short-circuit capability and feature 2/3 pitch windings. Three levels of sound attenuated enclosures are available: standard, basic (85 dBA) and maximum (75 dBA).
