Key Specifications

Core Advantages

1. Genuine Cummins 6L Heavy‑Duty Industrial Powertrain Cummins 6L 8.9L six‑cylinder engine is a well‑proven high‑power engine platform for generator applications. Turbocharged intercooled configuration optimizes air‑fuel mixing, bringing powerful output and excellent heat dissipation performance. Reinforced cast iron cylinder block adapts to long‑time heavy‑load continuous operation. Direct‑injection fuel structure ensures stable combustion, simple daily maintenance, and access to Cummins global spare‑parts supply network.
2. Foshan Stanford TFW Brushless All‑Copper Alternator Brushless excitation eliminates carbon‑brush wear‑and‑tear failure points, effectively lowering maintenance workload for 24/7 critical power‑supply projects. Full pure‑copper winding delivers outstanding heat dissipation and strong overload resistance. Built‑in AVR automatic voltage regulator stabilizes output voltage efficiently, protecting large‑scale production equipment, medical systems and commercial power‑consuming facilities. H‑class insulation and IP23 protection grade adapt to complex dusty and humid field working environments.
3. Precision Electronic Speed Governing System Electronic governor makes rapid adjustment under drastic load fluctuation, keeping stable rotating speed and output frequency. Optimized direct‑injection fuel system reduces carbon‑deposit accumulation and extends engine overhaul intervals. DC24V heavy‑duty electric starting ensures reliable startup under various ambient‑temperature conditions.
4. Heavy‑duty Integrated Welded Base & Practical Maintenance Layout High‑strength one‑piece welded base bears the full weight of the whole unit and suppresses mechanical vibration effectively. Oil filling ports, filter replacement positions and inspection openings are reasonably arranged for convenient on‑site inspection and spare‑part replacement. Every finished genset passes strict full‑load aging test before factory delivery to verify all mechanical and electrical performance indicators.
5. Flexible Customization For Diverse Large‑scale Projects Open‑frame layout reserves sufficient installation space for auxiliary accessories. It supports configuration of silent canopy, ATS automatic transfer cabinet, remote cloud monitoring module and extended fuel tank, meeting diversified power requirements of industry, medical treatment, commerce and mining projects.
