Key Specifications

Core Advantages

✅ V12 Large Displacement Turbocharged Intercooled Heavy-Duty Engine: The STF1320 V12 engine with 30.2L large displacement, turbocharged intercooled structure. It possesses enormous torque reserve to cope with instant heavy load shocks, sustaining stable full-load running for extended periods under harsh site conditions.

✅ TFW Brushless Self-Excited All-Copper Alternator: Brushless structure removes carbon brush wear and routine replacement work, cutting long-term maintenance cost. All-copper winding paired with AVR automatic voltage regulator maintains steady voltage output even under frequent load changes, perfect for non-stop critical power applications. 

✅ Reliable Mechanical Speed Governing System: Mature mechanical governor features simple, durable structure with outstanding resistance to high temperature and dust. Less prone to electronic faults, highly suited for rugged mining sites and heavy industrial environments. 

✅ Ultra-large Heavy-duty Water Cooling System: Custom oversized radiator ensures stable operation under ambient temperature up to 40℃, effectively preventing overheating issues during continuous full-load operation. 

✅ IP23 Protection & Class F Insulation: F-class winding insulation enhances high-temperature tolerance; IP23 rating stops solid particles and splashing water, adapting well to semi-outdoor and complex heavy-duty working scenarios.

🎯 Application Scenarios

Super-large mining continuous power supply, heavy industrial park main power, large data center emergency backup, municipal large sewage treatment plant, huge infrastructure construction, remote off-grid power station. Designed for ultra-heavy load and long-cycle continuous operation.

⚙️ Optional & Customization

• Silent canopy / Mobile trailer chassis
• ATS automatic transfer switch for automatic startup once mains power fails
• Multi-protection control system (overspeed, high temperature, low oil pressure, overcurrent protection)
• Extended base fuel tank, remote monitoring module
• Custom painting and brand logo printing
