Cummins 252kW Silent Diesel Generator For Hospitals, Data centers, and Residential Areas

The Cummins 252kW silent diesel generator set is a high-quality power supply solution that seamlessly integrates reliable power delivery, stable power generation, and low-noise operation. Not only does it demonstrate exceptional adaptability under challenging operating conditions, such as high temperatures, high humidity, high altitudes, or continuous heavy loads, but it also stands out as an ideal choice for providing backup or primary power supply to communication base stations, hospitals, data centers, commercial buildings, construction sites, and industrial facilities, thanks to its compact silent design, intelligent control system, and user-friendly maintenance features. This diesel generator combines a Cummins 6LTAA8.9-G2 engine with a Leroy-Somer TAL-A46-EJ generator, supported by a Dingbo  silent canopy and a Deep Sea controller, delivering a comprehensive, efficient, and reliable power supply solution covering the entire spectrum, from power generation and output to operational environment management.

The Cummins 6LTAA8.9-G2 engine provides robust reliability support for the entire system. With a displacement of 8.9 liters and a curb weight of 650 kg, it operates at an idle speed of 900 rpm and features a solid structural design along with excellent thermal load resistance. Its primary power output reaches 220kW at 1500 rpm and 235kW at 1800 rpm; its backup power outputs are 240kW at 1500 rpm and 258kW at 1800 rpm, enabling it to seamlessly meet both normal continuous power supply and emergency backup requirements. At rated power, its fuel consumption is only 195 cm³ per stroke, demonstrating high fuel efficiency. More importantly, Cummins engines are renowned for their durability, stability, and broad fuel compatibility; even under demanding operating conditions of prolonged continuous operation, frequent start-stop cycles and significant load fluctuations. They maintain consistent power output and a low failure rate. For users requiring continuous power supply, these "environmentally adaptable and load-resistant" engine characteristics are crucial for ensuring the long-term safe operation of the power unit.

The Leroy-Somer TAL-A46-EJ 6S/4 generator, matched with a Cummins engine, further enhances the overall electrical performance and power supply quality of the system. This generator delivers a rated power of 252kW and can maintain its rated output even at an ambient temperature of 40°C; its rated current is 413 A, power factor is 0.8 (lagging), output voltage is 440 V, and frequency is 60 Hz, enabling it to provide stable, clean electrical power to connected loads. The generator features an IP23 protection rating and an H-class insulation class, offering superior temperature resistance. Even under high-temperature condition or internal temperature rises significantly, it can guarantee a robust insulation safety margin . With a net weight of 754 kg, the generator boasts a compact design and excellent structural rigidity. Its full-load excitation parameters are 39.24 V/2.87 A, while the no-load excitation current is only 0.55 A, indicating a rapid excitation system response and high regulation accuracy and allowing the generator to quickly and stably maintain voltage during sudden load changes and minimize the impact of voltage fluctuations on downstream equipment. Leroy-Somer generators are renowned in the global market for their high efficiency, low harmonic content, strong overload capacity, and long service life; their seamless integration with Cummins engines has been meticulously calibrated to achieve optimal synergy between the system's mechanical and electrical performance.

The noise reduction feature is a standout advantage of this Cummins 252kW silent diesel generator set. The unit comes standardly equipped with a noise reduction enclosure fabricated from 2 mm thick galvanized steel sheet – a material that offers excellent corrosion resistance and structural strength, while effectively suppressing enclosure-related resonant noise. The interior of the noise reduction enclosure features comprehensive noise reduction measures targeting engine mechanical noise, intake and exhaust noise, and fan noise; when combined with a well-designed heat dissipation air duct system, this ensures optimal cooling efficiency while significantly reducing noise disturbance to the surrounding environment. During actual operation, the unit's noise level is effectively kept at a relatively quiet level, making it particularly suitable for applications such as hospitals, hotels, office complexes, areas adjacent to residential neighborhoods, or locations where strict noise control is required. The noise reduction enclosure is not merely an additional external casing; rather, it incorporates an integrated design that combines noise reduction, heat dissipation, rain and dust protection, as well as dedicated access channels for routine maintenance. This design meets the ventilation and cooling requirements during prolonged unit operation, while also facilitating maintenance personnel in inspecting and servicing components such as the engine, generator, filters, and battery.

For intelligent control, the generator set is equipped with a Deep-Sea Controller featuring self-starting, automatic switching, parallel operation, load distribution, and comprehensive engine and generator protection functions. This controller boasts strong anti-interference capability, making it suitable for operating environments characterized by severe vibration, high temperatures, and high humidity; it also supports remote communication, enabling seamless integration with cloud-based monitoring platforms for real-time remote monitoring, fault alarm functionality, and unattended operation management. When paired with the two standard battery banks, the generator set can be quickly started and put into service during mains power supply anomalies, thereby minimizing losses caused by power outages.

The Cummins 252kW silent diesel generator set combines a reliable engine, a stable generator, exceptional noise reduction performance, and intelligent control systems to provide users with a dependable and safe power supply solution. In addition to this power range, Dingbo also offers diesel generator sets ranging from several kilowatts to several kilowatts of power, catering to diverse electricity requirements across various environments and application scenarios.
