Key Specifications

Core Advantages

✅ Strong Power Reserve for Extreme Heavy-Duty Workloads This 12-cylinder large-displacement power plant comes with generous power margin. It can cope with abrupt load spikes effortlessly and maintain stable full-load operation over long continuous hours, satisfying enormous power consumption demands of large heavy industrial equipment.

✅ TFW Brushless All Copper Alternator 100% pure copper winding construction with rapid AVR voltage adjustment and low harmonic waveform distortion. It offers solid protection for precision electrical devices and greatly cuts regular maintenance work when compared with brushed generator solutions.

✅ Heavy-Duty Large-Capacity Circulating Water Cooling System Specially customized oversized water radiator delivers outstanding heat dissipation efficiency. It keeps engine temperature stable under high ambient temperature and round-the-clock continuous running, preventing unexpected overheating shutdowns.

✅ Convenient Routine Service & Lower Long-Term Running Costs Optimized engine structural layout grants easy access for oil changes, filter replacement and daily inspection. National II emission design removes complex after-treatment assemblies, helping end users reduce recurring operation and maintenance expenses.

✅ Reinforced Thick Base Frame with Vibration Damping Thickened base frame fitted with high-performance shock-absorbing pads to minimize vibration transmission during genset operation, improving overall unit stability and extending the total service life of the whole power system.
