Our diesel generator set production workshop is a specialized facility where we manufacture a wide range of diesel generator sets. With advanced equipment and skilled workers, we ensure high-quality production and efficient work procedures.
In this workshop, we produce diesel generator sets with various power outputs, from 7KW to 3000KW. Our products are mainly powered by well-known brands such as YUCHAI, WEICHAI, SHANGCHAI, MTU, and SHANGYAN diesel engine companies. This generator sets applications in industries such as telecommunications, construction, mining, and emergency power supply.With years of experience in the industry, we have gained a reputation for reliable and high-quality diesel generator sets. Our production workshop is committed to providing customers with excellent products and services, and we strive to become a leading manufacturer in the global diesel generator set market.
The world's top brand engines and the most advanced fuel high-pressure common rail technology (for some models) are used to get the best fuel consumption rate. The combustion temperature and air-fuel ratio in the cylinder are more accurately controlled, and the compression ratio is higher to ensure more efficient power output and lower emissions.
Generator excitation system with the most advanced solid-state automatic voltage regulator (AVR) or digital voltage regulator (DVR). The windings are made of high quality, high temperature and high voltage resistant enamelled wire, insulating materials and insulating coating to ensure electrical reliability and insulation safety. The generator also has the characteristics of short transient voltage recovery time, with strong non-linear load capacity and electromagnetic compatibility.
The digital system uses a microprocessor as the core, with multiple languages available for selection, and it can be automatically controlled. Connected to the power supply through ATS, can perform automatic switching between the mains power supply and the backup power supply, and also the parallel connection of multiple generator sets to meet the power supply needs of the generator sets.
Through the noise analysis software calculations and a variety of combinations of noise reduction solutions, reduce the fan rotation noise, eddy noise and engine exhaust noise effectively. The unit adopts a high-performance impedance integrated silencer that can reduce the noise by 15 to 35dB(A), greatly reducing the unit's operating noise and the impact on the surrounding environment, this makes our generator sets more suitable for use in the night, residential, office and other noise-sensitive environments.
We use well-known brand radiator assemblies to provide the most suitable radiator for different brands and models of engines to perform the best heat dissipation effect and equip the radiator with a protective cover to ensure the safe operation of the user.

Diesel generators are widely used in animal husbandry, shipping transportation, steamship, garbage disposal, water conservancy and hydropower, factory backup, outdoor welding, metallurgy mining, cold storage, municipal engineering, civil air defence projects, flood control and drought relief, highways, railway, hotels and guesthouses, real estate, data, communications industry, fire backup and other industries.
To ensure the quality of our diesel generator sets, we require strict and careful testing at each stage of production. All products have passed CE, ISO9001:2015, ISO14001:2015, and ISO45001:2018 certification. We also have a professional research and development team that continuously improves our product design and develops new models to meet market demands.
