Air-Cooled Backup Generators

Air-cooled gensets run a finned-cylinder air-over-fan cooling architecture, eliminating the radiator, coolant pump, and freeze-protection complexity of a liquid-cooled unit. The trade-off is shorter engine life and a hard ceiling at roughly 26 kW residential. Most residential standby gensets in the United States are air-cooled gas.
