| Air-Cooled vs. Liquid-Cooled Generators |
| By Jon Hoch, Founder (Bolingbrook, IL) |
The more electricity that you want to generate… the more complicated the generator.
As the name suggest, air-cooled engines -- think lawnmower – intake cold air to keep it from overheating.
Air-cooled standby generators can generate up to 20 kilowatts of electricity -- enough to power most single-family homes.
If you need to power a luxury home or a light commercial building, you need a liquid-cooled standby generator instead.
Instead of lawnmower-like engines, liquid-cooled generators feature automobile-like engines that use anti-freeze to keep them from overheating.
Liquid-cooled engines are more expensive, durable and powerful, generating from 22 to 150 kilowatts of electricity.
Surprisingly, the bigger engines are actually quieter too. When exercising, the sound output is comparable to an idling car. |
