Core Advantages
1. Optimized 640kW Tiered Power
Perfectly calibrated for medium-large industrial loads, this unit avoids the capital waste of over-sized equipment while providing a 10% standby margin to handle sudden startup spikes.
2. 4600 N·m High-Torque Reserve
Specifically designed to handle transient loads (cranes, pumps), this high torque reserve prevents voltage drops and relay trips, maintaining process stability in complex construction environments.
3. 12-Hour Continuous Operational Autonomy
The 1200L integrated fuel tank ensures 12+ hours of runtime at 75% load, significantly reducing labor and logistics pressure for off-grid and remote mining project managers.
4. Clean Power for Automation
With THD<5%, the system delivers clean power that protects PLC systems, industrial robots, and banking/data servers from harmonic interference, preventing costly downtime and malfunctions.
5. Yuchai Heavy-Duty Reliability
Built on Yuchai’s mature inline-six platform, this generator features enhanced thermal management and reinforced structural components, proven for 24/7 reliability in extreme, high-temperature, and dusty conditions.
