In challenging industrial environments where reliability is non-negotiable, our engineering solutions make all the difference. This September, 2025, we delivered a 400kW Cummins generator set, meticulously customized for an application characterized by high-dust conditions and demanding operational hours. By October, the client in Dubai reported exceptional satisfaction, affirming the system’s flawless performance and durability.
The power is Cummins QSZ13-G3 engine—a model renowned for its high efficiency, low emissions, and outstanding reliability in continuous operation. Specifically chosen for its superior combustion technology and enhanced filtration capabilities, it ensures stable performance even in dusty surroundings, reducing maintenance needs and downtime.

The alternator is adopted Shanghai Stamford GR355D, known for its excellent voltage regulation, high surge resistance, and reliable power output. This combination delivers not only consistent energy but also long-term operational economy and environmental compliance.
