This is a 400 kW open type natural gas generator set powered by Cummins, designed for high-power continuous and standby power applications in demanding industrial and commercial environments. The generator set integrates a Cummins dedicated natural gas engine, high-efficiency alternator, intelligent control system, and a heavy-duty steel base frame. With its open-frame configuration, the unit offers excellent heat dissipation, easy maintenance access, and high operational reliability, making it ideal for generator rooms and power stations where noise control is handled separately.
The generator set is driven by a Cummins natural gas engine developed specifically for gaseous fuel operation rather than diesel conversion. The engine is engineered for stable combustion, strong load response, and long service life under continuous operation. Optimized ignition control and precise air–fuel ratio management ensure smooth running, low vibration, and consistent power output, even under high-load conditions.
The open type structure exposes all major components, allowing direct access to the engine, alternator, and auxiliary systems. This design ensures efficient ventilation and heat dissipation while significantly simplifying inspection, servicing, and routine maintenance. Maintenance tasks such as oil changes, filter replacement, and system checks can be performed efficiently without removing enclosure panels, reducing downtime during long-term operation.
The heavy-duty base frame is designed to support the high power output and weight of the generator set. Reinforced mounting points and a robust structural layout ensure stability during operation and transportation, contributing to long-term durability and reliable performance in industrial environments.
The intake and exhaust systems are designed with industrial-grade piping and secure connections to withstand high temperatures and continuous operation. Proper routing of exhaust components ensures smooth airflow, effective heat management, and safe operation under varying load conditions.
Fuel supply and engine auxiliary systems are arranged in a clear and organized layout. Key components are positioned for accessibility and safety, supporting reliable gas delivery and stable engine operation. This layout also simplifies troubleshooting and routine inspection during daily operation.
The generator control system provides comprehensive monitoring and protection functions. Operating parameters such as voltage, current, frequency, and output power are continuously monitored to ensure stable operation. The control system includes multiple protection features such as overload, overspeed, high coolant temperature, low oil pressure, and emergency shutdown, ensuring safe and reliable operation under various working conditions.
Detailed engine and system components are shown in the internal close-up views, highlighting the professional configuration and robust construction of the generator set. High-quality components and careful assembly contribute to long service life and dependable performance.
The generator set’s auxiliary piping and connection systems are designed for durability and ease of maintenance. Clear routing and secure fastening improve operational safety and facilitate inspection and servicing during long-term operation.
