The 20KW Open Frame Diesel Generator is delivering 20KW prime power and 22KW standby power. Featuring a lightweight, open-frame structure, this cost-effective medium-and-small power solution is engineered for outdoor temporary power supply and small fixed loads, combining ease of operation with reliable performance.
All core components undergo strict quality inspection. The Hanma engine ensures robust power output and low fuel consumption, supporting long-term continuous operation. The open-frame design enables efficient heat dissipation and unobstructed access, allowing for daily inspection and maintenance without disassembly, thus minimizing operational costs and downtime. Equipped with an electric start system for one-button operation, the generator is fitted with an AVR automatic voltage regulator that guarantees stable output with low waveform distortion. It safely powers resistive and inductive loads such as water pumps, lighting systems, small machinery, and office equipment.
With its compact size and easy installation, this generator is widely used in outdoor construction, commercial backup power, breeding farms, small processing plants, municipal maintenance, and field operations. It serves as both a temporary prime power source and an emergency backup, effectively resolving power outage issues. Leveraging Hanma’s mature engine technology, the unit offers excellent energy efficiency, durability, and cost performance, making it the ideal choice for stable power supply in medium-and-small power applications.
