Key Specifications

Core Advantages

✅ V12 Turbocharged Intercooled Heavy-Duty Engine: The 12V135 series STF V-type 12-cylinder engine, with displacement up to 26.6L, turbocharged intercooled design. It provides massive torque reserve to withstand sudden heavy load impacts, maintaining stable operation for long continuous heavy-duty cycles.

✅ TFW Brushless Self-Excited All-Copper Alternator: Brushless design removes carbon brush wear and frequent maintenance. Full copper winding plus AVR automatic voltage stabilizer maintains consistent voltage output under frequent load fluctuations, ideal for continuous long-running operation.

✅ High-precision Electronic Speed Governing: Electronic governor achieves fast and accurate speed adjustment. It quickly responds to load changes and minimizes speed fluctuation, protecting high-value sensitive industrial and data center electrical equipment.

✅ Heavy-duty Large Volume Water Cooling System: Custom large radiator supports continuous operation under ambient temperature up to 40℃, preventing overheating faults during long-hour full-load operation.

✅ IP23 Protection & Class F Insulation: F-class winding insulation enhances high-temperature resistance; IP23 protection blocks solid particles and splashing water, adapting to rugged industrial, mining and semi-outdoor installation environments.

🎯 Application Scenarios

Large mining continuous power supply, industrial park main/standby power, data center emergency backup, large sewage treatment plant, large construction infrastructure, remote off-grid power stations. Built for heavy-load and long-duration continuous operation.
