Industrial-Grade Performance and Engine Design

At the core of the Cummins RS80 Quiet Connect 80kW Generator 120/240 Volts 3 Phase is a 5.9L inline 6-cylinder turbocharged and aftercooled engine.

Key engine specifications:

• 5.9 Liter displacement

• Inline 6-cylinder configuration

• Turbocharged & aftercooled

• Cast iron block construction

• Liquid cooled system

• Rated speed: 1800 RPM

Running at 1800 RPM significantly extends engine life compared to high-speed generators. Lower RPM operation reduces internal wear, improves fuel efficiency, and enhances long-term reliability.

The engine operates on:

• Gás natural

• LP Propane

Fuel selection can be configured in the field, making this a versatile natural gas propane generator option for varying site requirements.
