Open Frame V-Twin Cylinder Diesel Generator Air-Cooled 10-18kW

The B-series V-twin air-cooled diesel generator is built for users who prefer a larger, more stable open-frame design with easy mobility on rough ground. Engine options range from 2V88F to 2V105F (912cc to 1524cc displacement), all V-twin, 4-stroke, air-cooled diesel engines with direct injection. Rated output spans 10kW to 18.5kW with max output from 10.5kW to 19kW.

The B-type frame uses a spacious open design similar to our water-cooled GF series, incorporating large rubber wheels that roll easily over gravel, dirt, grass, or uneven construction surfaces. This design provides better stability during operation and transport compared to compact frames with small wheels.

V-Twin Air-Cooled Diesel Engine for Reliable Power
The generator is powered by 2V88F to 2V105F V-twin, 4-stroke, air-cooled diesel engines with direct injection combustion. The V-twin configuration provides smoother power delivery and lower vibration compared to single-cylinder engines. Forged steel crankshaft comes with lifetime warranty—if the crankshaft breaks, the entire machine is replaced free of charge. Air-cooled design simplifies maintenance by eliminating coolant and radiator components, reducing potential failure points.

Large Rubber Wheels for Rough Terrain Mobility
Unlike compact A-series with four small wheels, the B-series uses two large rubber wheels combined with a stable open frame. This design rolls easily over gravel, mud, uneven construction sites, and grassy fields. The larger wheel diameter reduces pulling effort and improves stability when moving across job sites.

Spacious Open Frame with Premium Appearance
The B-frame shares design language with our higher-end water-cooled GF series, offering a more polished and professional look compared to typical compact generators. The open structure also provides good airflow for engine and alternator cooling, even during prolonged high-load operation. The aesthetic appeals to buyers who want equipment that looks as good as it performs—important for rental businesses, commercial contractors, and distributors serving premium market segments.

Long Runtime with 30L Fuel Tank
Runtime ranges from 4.3 hours at full load on the largest 18.5kW model to over 9 hours on lower-power 10kW models. This allows all-day operation on many job sites without refueling stops, improving productivity for contractors.

Protection and Starting Features
Electric start with heavy-duty pure copper starter motor ensures reliable ignition in cold or hot conditions. Low oil shutdown with LED indicator protects the engine from damage. DELIXI circuit breakers provide reliable overload protection. Optional intelligent control system allows custom safety limits for voltage, frequency, and automatically shutdown when overloading.

The open-frame V-twin air-cooled diesel generator is intended for rugged applications requiring easy mobility across varied terrain:

• Construction sites with gravel, mud, or uneven surfaces

• Workshops, auto repair shops, and fabrication facilities

• Backup power for commercial buildings and industrial sites

• Remote job sites where generators need frequent move

It serves B2B buyers supplying industrial, business, and rental markets where rough-terrain mobility and professional appearance matter.

Can I buy several samples to test our market?
Yes, we can supporrt you with trial orders(typically mimimum 5 units). MOQ can be adjusted based on your plan of purchasing.

What is the difference between B-series and A-series?
Both share the same V-twin air-cooled engines and electrical specifications. The difference is in the frame and wheels. B-series has a larger open frame with two big rubber wheels, similar to our water-cooled GF series, offering better rough-terrain mobility and a more premium look. A-series has a compact frame with four small wheels, better for tight storage spaces.

Why choose air-cooled over water-cooled for a V-twin?
Air-cooled eliminates the need for coolant, radiator, hoses, and water pump, reducing maintenance issues. It is also lighter and typically lower cost. However, water-cooled provides better temperature stability for extreme continuous duty. Choose based on your expected duty cycle and operating environment.

Do you have this machine in stock?
We typically do not keep high stock on hand, as each machine is custom-made in terms of appearance, color, and panel configuration, allowing us to provide you and your customers with a higher level of service. If your request is urgent, please contact us promptly so we can provide the fastest production and shipping options.
