What is the difference between an air-cooled and a liquid-cooled generator?
There are a few differences between air-cooled and liquid-cooled generators. First, air-cooled generators operate at 3600 RPM whereas liquid-cooled generators have engines that operate at a variety of speeds. Most residential liquid-cooled generators operate at 1800 RPM. Second, liquid-cooled generators utilize a radiator, similar to your vehicle, to cool the engine while air-cooled generators use a fan to cool the engine. Operationally both air-cooled and liquid-cooled generators are the same, but the liquid-cooled generators have a much longer run-time between necessary servicing. Generators burn oil and, depending on a number of factors, will need to have oil added after a period of time. The largest air-cooled generator is a 20 kW (LP, 18 kW NG) while the smallest liquid-cooled generator is a 22 kW (LP or NG). And finally, air-cooled generators are smaller in size than liquid-cooled generators. For more information, please contact us and we’ll discuss the advantages and disadvantag
