Air-cooled standby generators blow air over the engine to cool it. Liquid-cooled standby generators pump coolant through the engine to a radiator and fan for efficient cooling much like a car.
When it comes to engine cooling, liquid-cooled home standby generators have the advantage. An efficient cooling system uses liquid coolant to remove heat from the engine and transfer it outside the generator. Standby generators have safety mechanisms that prevent them from operating under conditions that damage them. An air-cooled home generator may shut down when the surrounding air temperature prevents them from adequately cooling itself.
For most of the United States, air-cooled standby generators are the most efficient and cost effective for homeowners. Those in the hot southwest climate benefit from the added reliability of liquid-cooled generators.
Effective cooling limits air-cooled generators to 20 to 24 kilowatts. Liquid-cooled standby generators don’t have an upper limit. Manufacturers produce 15 to 60-kilowatt liquid-cooled generators for home use and higher capacity models for estates, farms, and commercial installations.
