What Is a Liquid-Cooled Generator?

A liquid-cooled generator is the most reliable choice for backup power.

How it works:

Just like your car or truck, these generators use:

  • Engine oil or specialized coolant
  • A radiator
  • A water pump
  • Hoses throughout the engine

This cooling system circulates liquid to keep the engine at the right temperature. It works even in extreme conditions.

Built to Last

Cummins generators feature:

  • Industrial-grade materials
  • Protective powder coat paint 
  • Enclosed design that protects parts from weather
  • Resistance to corrosion
  • Wind resistance up to 180 mph

Remarkably Quiet

You'll barely notice when your generator turns on. This is thanks to:

  • 1800 RPM engine speed
  • Sound-reducing enclosures
  • Precision-balanced parts

Perfect for neighborhoods where noise matters.

Liquid-Cooled vs. Air-Cooled

Air-cooled generators work for smaller needs and short outages. But liquid-cooled generators offer more:

Advantages of liquid-cooled:

  • Longer runtime - Runs continuously without overheating
  • More power - Higher kilowatt ratings for whole-home coverage
  • Greater durability - Longer engine life, less maintenance
  • Weather-resistant - Works in any conditions
  • Lower costs - Better fuel efficiency saves money during long outages
