Winco PSS60LS – Standby Generator


The housing on each WINCO packaged standby generator is designed to extend equipment life and reduce noise. Each housing is constructed of galvaneal steel. The sheet steel is treated with a galvaneal coating which inhibits rust even if the paint layer is damaged. After each piece of sheet steel is punched and formed in our facility it is washed in a multi-phase phosphate system. The part is then powder coated and baked in the oven to cure the paint. The final result is an incredibly durable part that can withstand the elements without compromising structural strength. WINCO also uses design features like solid roof designs, drip edges and baffle systems to keep the weather out, protecting your investment. A sound absorbent foam is applied to the inside of the housing to reduce the noise and the baffles prevent direct lines for noise to escape the enclosure.
