  • Winco PSS60 60kW Backup Generator - LP Vapor or Natural Gas

    Regular Price:

    $22,135.00
    A key part of any generator is the fuel system. If the engine is starved or flooded, the governor is unable to maintain the proper speed resulting in large voltage and frequency variations. The WINCO PSS90 and all other WINCO emergency standby generator models include industrial features to ensure that your emergency generator will start and perform to specification when your family or business needs it. To control the fuel supply and prevent dangerous fuel leaks WINCO utilizes dual ASCO normally closed solenoids. WINCO uses ASCO valves designed to properly operate in cold temperatures to increase generator reliability. The GM engines include a dynamically controlled valve and fuel mixer that ensures the ideal fuel to air ratio is always achieved to maximize performance while minimizing emissions. The engines also include electronic governors capable of quickly and accurately adjusting the engine speed to maintain the most consistent electrical output possible through a wide range of load conditions.
