Key Specifications

Core Advantages

✅ Strong Power Reserve for Extreme Heavy-Duty Workloads This 12-cylinder large-displacement power unit reserves sufficient power margin. It can respond smoothly to sudden load surges and maintain stable full-load continuous operation for long hours, meeting the huge power consumption needs of large heavy industrial equipment.

✅ TFW Brushless All Copper Alternator Adopts full pure copper winding design, with fast AVR voltage regulation and low waveform distortion. It effectively protects precision electrical equipment and greatly reduces daily maintenance workload compared with brushed generator models.

✅ Heavy-Duty Large-Capacity Circulating Water Cooling System Custom oversized water radiator brings excellent heat dissipation performance. It keeps the engine temperature stable under high ambient temperature and non-stop all-day operation, avoiding unexpected shutdown caused by overheating.

✅ Convenient Routine Service & Lower Long-Term Running Costs Optimized engine layout facilitates oil replacement, filter maintenance and daily inspection. National II emission structure does not require complex post-processing components, helping customers cut long-term operation and maintenance expenditure.

✅ Reinforced Thick Base Frame with Vibration Damping Thickened base frame fitted with high-performance shock-absorbing pads, which reduces vibration transmission during operation, improves the stability of the whole unit and extends the service life of the genset.
