Are you searching for a silent, compact, and powerful generator with minimal fluctuations? Meet the Yanmar YDG5500W Diesel Generator, which offers advanced features for durability, long-lasting operation, and fuel efficiency. Explore the top-of-the-line technology that makes Yanmar a trusted name in the generator market.

Compact Power with Direct Injection Air-Cooled Diesels: The YDG5500W stands out with its direct injection air-cooled diesel engine, among the smallest globally. This compact powerhouse ensures very good fuel savings, providing an economical and reliable power source. Despite its small size, it delivers high power with minimal fluctuations, making it an ideal choice for various applications.

Versatile Power with AVR Technology: Equipped with an Automatic Voltage Regulator (AVR), the YDG5500W provides low-fluctuation power delivery across a range of voltages from 110V to 240V. Each model also offers 12V D.C, useful for charging car or boat batteries (excluding 3-phase models). This versatility makes it suitable for a wide range of power needs.

Dusk-to-Dawn Operation without Fill-Up: With the YDG5500W, enjoy extended operation without frequent refueling. A single tankful of diesel can keep these air-cooled gensets running for 6 to 9.5 hours. The advanced features, including direct injection and low fuel consumption, contribute to long-lasting operation, providing savings with every tankful.

Total Carry-Around Convenience: The YDG5500W is designed for maximum convenience. Its extra-lightweight construction combines a small air-cooled diesel engine (Yanmar L-N type) with a highly compact and light U-frame generator. The size and weight trimming allow easy mobility and storage, making it a versatile and practical choice.

Peaceful Power with Advanced Noise Prevention: Experience quiet and long-lasting power with the YDG5500W. The inclined rubber block mounting system reduces both vertical and horizontal vibrations, providing a smooth and silent engine operation. Noise prevention measures are implemented at various levels, including intake, combustion system, and a well-muffled exhaust system.

Alarm System for Added Safety: The YDG5500W comes with an alarm system to reduce the chance of damage due to low oil-level operation. When the oil falls low, the alarm is activated, and the engine stops automatically. Additionally, the control panel sockets are recessed, and the muffler is enclosed with a cover for added safety.

Instant, No-Effort Starts and Easy Maintenance: Featuring an electric start with a battery installed, the YDG5500W ensures instant, no-effort starts. The short 70cm stroke of a recoil starter, along with auto-return decompression, makes starting quick and easy, even in low temperatures. With fewer parts and forced lubrication, maintenance is simplified, ensuring long-lasting durability.

Air-Cooled Diesel Engine L-N Series: Yanmar's micro-size fuel injection system in the L-N Series sets it apart. The brushless pump and a smaller nozzle contribute to the lightweight and compact structure. This engine, built by specialists in large diesel technology, is durable and features a convenient recoil starter, commonly associated with gasoline engines. With Yanmar's direct fuel injection system, fuel costs are minimized, and its very low vibration and quiet running make it an ideal choice for constantly operating machinery.

In conclusion, the Yanmar YDG5500W Diesel Generator offers a perfect blend of compact power, fuel efficiency, and silent operation. Whether you need versatile power, dusk-to-dawn operation, or total carry-around convenience, the YDG5500W delivers. Choose Yanmar for top-tier diesel generators that redefine reliability and efficiency in power generation.
