    Premium Industrial Power at an Exceptional Value – Two Proven Units Available for Immediate Deployment

    When your facility demands reliable, continuous power generation, settling for anything less than Caterpillar quality simply isn't an option. These pre-owned Caterpillar G3512 Natural Gas Generator Sets deliver an impressive 550KW of continuous-rated power, backed by the legendary durability and engineering excellence that has made Caterpillar the global standard in industrial power generation.

    Why These Generator Sets Stand Apart

    Each unit arrives fully equipped and ready to integrate into your power infrastructure, featuring factory-installed components that would cost thousands to add aftermarket. With meticulously maintained service histories and moderate operating hours, these generators represent a rare opportunity to acquire premium Caterpillar reliability at a fraction of new equipment costs.

    Complete Power Solution – No Hidden Costs or Surprises

    • 550KW Continuous Duty Rating (693KVA) – Dependable baseline power for mission-critical operations, data centers, manufacturing facilities, hospitals, and commercial buildings
    • Natural Gas Fuel System – Lower operating costs, cleaner emissions, and simplified fuel logistics compared to diesel alternatives
    • Remote Radiator Configuration – Flexible installation options with heat rejection located away from the generator for improved facility climate control
    • Dual Voltage Capability: 120/208V (Reconnectable to 480V) – Exceptional versatility to match your existing electrical infrastructure without costly transformers
    • 60Hz, 1200RPM Operation – Optimal balance of power density and longevity for continuous-duty applications

    Advanced Control & Monitoring Systems Included

    These aren't stripped-down units – each generator comes factory-equipped with professional-grade monitoring and control systems:

    • Caterpillar Engine Supervisory System with Digital Display – Real-time monitoring of all critical engine parameters for proactive maintenance and peace of mind
    • Miratech MEC2001 Air Fuel Ratio Controller – Precision fuel management ensures optimal combustion efficiency, reduced emissions, and lower operating costs
    • EnerGenius Battery Charger System – Maintains starting batteries at optimal charge levels, ensuring reliable starts when you need power most

    Verified Performance – Watch Them Run

    Don't take our word for it – see these generators in operation. We've documented full operational testing to demonstrate that these units start reliably, run smoothly, and perform to specification. View the test run video here and verify the quality for yourself before making your decision.

    Moderate Hours Mean Years of Service Ahead

    With approximately 10,753 hours on Unit 1 and 8,823 hours on Unit 2, these generators are just entering their prime operating years.
