Factory Tour

Dehray's generator production line is a state-of-the-art manufacturing system integrating precision engineering, intelligent automation and strict quality control, dedicated to crafting high-performance generators for industrial, commercial and residential applications.

Spanning over 10000 square meters, the line is divided into five core stages: component processing, stator and rotor assembly, engine-generator integration, testing and calibration, and final packaging. Equipped with CNC machining centers, robotic welding arms and advanced torque testers, it ensures every part—from copper windings to engine components—meets international standards. We implement real-time quality checks at each station, with a team of seasoned engineers overseeing the entire process to guarantee low noise, high energy efficiency and stable power output of our generators.

With a monthly production capacity of 1000 units, the line balances efficiency with customization, offering tailored solutions for different power requirements and fuel types (including diesel, gasoline and natural gas). Committed to sustainability, we also adopt eco-friendly manufacturing processes, minimizing waste and carbon footprint while delivering reliable power solutions to global customers.

At DEHRAY, we provide comprehensive OEM/ODM solutions tailored to the unique needs of global partners in the power equipment sector, covering the full lifecycle from product conceptualization to mass production and after-sales support.

For OEM services, we leverage our advanced production line and strict quality management system to manufacture generators under your brand name, adhering precisely to your specifications for power output, fuel type, dimensions, and performance parameters. We source high-grade components and apply standardized testing protocols to ensure every unit matches your brand’s quality benchmarks, whether you require small portable generators for residential use or heavy-duty industrial power systems.
