In today’s power generation industry, “silence” is no longer a marketing slogan, but a practical engineering requirement. For end users, noise level directly affects the operating environment, regulatory compliance, and long-term equipment reliability. This is especially true for applications such as data centers, telecommunications facilities, commercial buildings, and urban infrastructure, where generator sets must deliver stable power while operating within strict acoustic limits.

With this understanding, Jiangsu Jianghao Generator Set Co., Ltd. has always treated noise control as a complete engineering system rather than an optional feature. The Jianghao SILENT TYPE SERIES Diesel Generator Sets represent this philosophy in practice, combining verified acoustic performance with robust mechanical design.

In the accompanying video, a professional sound level meter is used to measure the operating noise of the generator set under real working conditions. The instrument is positioned at standardized distances, recording sound pressure levels while the unit is running. This non-contact acoustic measurement method is widely used in industrial diagnostics and reflects the actual noise levels experienced by users on site, rather than theoretical laboratory values.

The test results show that Jianghao silent diesel generator sets can maintain noise levels of 80–85 dB(A) at 1 meter and 75–78 dB(A) at 7 meters under standard silent configuration. With enhanced soundproofing solutions, noise levels can be further reduced to 70–75 dB(A) at 1 meter and 60–65 dB(A) at 7 meters. These figures meet—and in many cases exceed—common international requirements for silent generator applications, making them suitable for both industrial and noise-sensitive environments.

Such acoustic performance is not achieved through simple external enclosure design alone. Effective noise reduction in diesel generator sets requires a systematic approach that integrates structural design, material selection, airflow management, and exhaust noise control.

Jianghao silent generator sets feature a fully enclosed canopy constructed from 2 mm thick high-strength steel plates. This structure provides excellent rigidity while ensuring effective sealing against rain, snow, and dust. The enclosure is designed for long-term outdoor and all-weather operation, offering both acoustic insulation and mechanical protection in harsh environments.

Inside the enclosure, a multi-layer acoustic treatment system is applied. High-, mid-, and low-frequency PUR flame-retardant sound-absorbing materials are strategically arranged to address different noise sources generated during operation, including mechanical vibration, electromagnetic noise, and structural resonance. These materials are selected not only for their sound absorption efficiency but also for their durability, flame resistance, and suitability for high-temperature, continuous-duty applications.

Exhaust noise is another critical factor in overall sound control. Jianghao silent diesel generator sets are equipped with high-efficiency resistive mufflers, designed to effectively attenuate exhaust noise and prevent low-frequency sound from propagating over long distances. Through coordinated acoustic design, the overall noise output of the generator set is reduced in a balanced and stable manner.

While achieving low noise levels, Jianghao also emphasizes practicality and ease of use. The generator sets feature a compact and well-organized internal layout, promoting efficient airflow and heat dissipation while simplifying inspection and maintenance. Integrated lifting points allow for convenient transportation and installation, enabling rapid deployment across different project sites.

At the core of every silent generator set is reliable power generation performance. Jianghao SILENT TYPE SERIES covers a wide power range from 8 to 4000 kVA, with a minimum order quantity of just one set, providing flexible solutions for applications ranging from small commercial backup power to large-scale industrial and infrastructure projects.

The generator sets can be configured with internationally recognized engine brands such as Cummins, Perkins, Volvo (Sweden), Doosan (Korea), Weichai, and SDEC, and matched with world-class alternators including Stamford, Leroy Somer, Marathon, Hengsheng, and other reputable brands. This combination ensures stable output, high efficiency, and long service life.
