625kVA SDEC Generator

SDEC generator sets are industrial-grade power generation equipment developed and manufactured by Shanghai Diesel Engine Co., Ltd. (SDEC), a company founded in 1947. SDEC’s entire product line is self-developed and self-produced. SDEC’s full range covers power from 10kW to 2900kW, encompassing both diesel and gas engine models, supporting multiple application scenarios including land and sea, and compatible with global 50/60Hz power grid standards. With high power reserves, ultra-low fuel consumption, strong adaptability to extreme environments, and stable power supply performance, they are widely used in data centers, precision manufacturing, mining and oil fields, infrastructure projects, commercial buildings, and other fields, making them a cost-effective mainstay power generation equipment for overseas projects.

Product Features

  1. Over 70 years of military-grade manufacturing experience, Shanghai Diesel Engine Co., Ltd. (Shanghai Diesel) ensures high-quality, stable operation, longer lifespan, and low failure rate.
  2. High-pressure common rail four-valve injection ensures complete combustion and lower fuel consumption, saving 5%–8% compared to similar products, while meeting emission standards.
  3. HEUI electronic control + digital speed regulation provides fast transient response, minimal fluctuations, and stable power supply, making it suitable for highly sensitive environments.
  4. High-strength cast iron cylinder block + forged steel crankshaft resists heavy loads and fatigue, supporting full-load operation year-round, suitable for high-load conditions.
  5. H-class insulated pure copper brushless motor is high-temperature resistant, short-circuit resistant, has a long lifespan, low failure rate, and ensures safe and economical long-term operation.
  6. Optimized heat dissipation + highly adaptable intake design ensures stable power output even at 55℃ high temperatures and 5000-meter altitudes, operating stably in harsh environments.
  7. Modular design facilitates easy maintenance, extending maintenance cycles and reducing maintenance frequency by over 30%, resulting in lower operating costs.
  8. Global service network + original factory warranty, 24-hour response, sufficient parts, and worry-free after-sales service at home and abroad.
