Liquid-Cooled engines will last several times the hours of air-cooled models. All Winco liquid-cooled generators operate at 1800 rpm improving life and fuel economy. The GM Vortec industrial engines start quickly in an emergency and with electronic fuel and governor controls your standby generator will meet the most stringent generator standards. The emergency generators are outfitted with sophisticated safety controls that protect your emergency generator and home from damage. The control constantly monitors engine and electrical inputs and outputs to make sure everything is performing to standards. If a dangerous condition occurs, the generator will automatically shut itself off. The best part is that there isn’t any guessing. The generator provides error codes with vital diagnostic information. Winco liquid-cooled generators are normally available from inventory from 21-90kW.
