This 240kW (300kVA) silent diesel generator set adopts genuine DCEC Cummins 6LTAA8.9-G3 inline six-cylinder industrial diesel engine, matched with world-famous Stamford brushless alternator. Equipped with heavy-duty fully enclosed silent canopy, the unit complies with ISO 8528 and CE standards.
It supplies stable three-phase AC power for prime power and emergency standby power applications. The optimized noise reduction enclosure effectively lowers operating noise, perfectly suitable for noise-sensitive areas including hospitals, commercial complexes, hotels, residential districts, office buildings, data centers and sewage treatment plants. Robust matching design supports long-time continuous operation under variable load conditions for commercial and industrial projects.
- Genuine Dongfeng Cummins Power Core: Original DCEC 6LTAA8.9-G2/6LTAA8.9-G3 four-stroke water-cooled engine, turbocharged & air-air intercooled structure with electronic governor. Proven mature structure, strong overload capacity and excellent environmental adaptability. Global Cummins after-sales network ensures convenient spare parts supply and maintenance worldwide.
- High-Grade Stamford Brushless Alternator: Famous Stamford brushless self-excited alternator, 100% pure copper winding, built-in high-performance AVR automatic voltage regulator. Low harmonic distortion, rapid voltage response and strong motor starting capability. Insulation Class H, protection grade IP23, safe for precision electronic equipment.
- High-Performance Silent Soundproof Canopy: Galvanized anti-corrosion steel canopy filled with multi-layer sound absorption material, large industrial muffler and optimized intake & exhaust silencing channels. Noise level ≤72dB(A) @7 meters. Rainproof, dustproof design enables permanent outdoor installation without dedicated generator room.
- Intelligent Digital Control System: Standard SmartGen or Deepsea digital controller. Real-time monitoring of voltage, frequency, coolant temperature, oil pressure, running hours and load rate. Complete alarm and emergency shutdown protection against abnormal working conditions. ATS automatic transfer switch is optional for unattended backup power system.
- Integrated Base Frame & Vibration Isolation: Heavy steel base frame with built-in fuel tank. High-density rubber vibration dampers greatly reduce vibration transmission between power assembly and silent canopy.
