Motorleistung und Zuverlässigkeit

At the core of this unit is a turbocharged and aftercooled 2.4-liter inline 4-cylinder Cummins engine.

Key engine characteristics:

• 1800 RPM operation for long service life

• Liquid-cooled system

• Cast iron block construction

• Designed for continuous standby applications

• Fuel selectable at installation (Natural Gas or Propane)

Operating at 1800 RPM instead of 3600 RPM reduces:

• Mechanical stress

• Fuel consumption spikes

• Long-term wear

• Noise output

This lower-speed design significantly improves engine longevity compared to smaller residential standby units.
