The WINCO PSS21 is designed to provide the most reliable emergency electrical power of any generator in its class. Most 20kW generators sold are air-cooled 3600 RPM generators available in single phase only. WINCO's PSS21 is powered by a liquid-cooled 1800 RPM engine that is capable of lasting several times longer than the air-cooled models. Whether you are protecting your family or business, the obvious choice for dependable emergency generator power is the WINCO PSS21.
