Dongfeng Cummins diesel generators from Unified Power deliver reliable and high-performance power solutions in the 16kW to 200kW range. Powered by genuine Dongfeng Cummins (DCEC) engines, these generator sets are designed for both prime and standby applications across industrial, commercial, and infrastructure projects.

Dongfeng Cummins engines are produced by Dongfeng Cummins Engine Co., Ltd., a 50/50 joint venture between Cummins Inc. and Dongfeng Motor Group. The series used in our generator sets includes the well-proven B-series, C-series, and L-series engines, such as 4B3.9-G, 4BT3.9-G, 4BTA3.9-G2, 6BT5.9-G2, 6BTA5.9-G2, 6BTAA5.9-G2, 6CTA8.3-G2, 6CTAA8.3-G2, and 6LTAA8.9-G2. These engines feature in-line 4-cylinder and 6-cylinder configurations with displacements ranging from 3.9 liters to 8.9 liters.

Key technical advantages of Dongfeng Cummins engines include turbocharging and air-to-air aftercooling (in TA and TAA models), which significantly improve power density and fuel efficiency. The engines operate at 1500 rpm for 50Hz applications and deliver excellent load response, low fuel consumption, and stable performance under continuous operation. Most models use Cummins’ proven PT (Pressure-Time) or mechanical fuel systems, ensuring precise fuel injection and reliable cold-start capability even in low-temperature environments.

Our Dongfeng Cummins generator sets are available in both open type and silent canopy configurations. Open type units are compact and suitable for indoor rooms or container installations, while silent type models feature sound-attenuated enclosures that typically reduce noise levels to 70–78 dB(A) at 7 meters. Each set is paired with high-quality brushless alternators (Stamford, Marathon, or equivalent) offering Class H insulation, IP23 protection, and automatic voltage regulation (AVR) for stable voltage output within ±1%.

Standard technical features include:

• Deep Sea or SmartGen digital control panels with automatic start/stop, remote monitoring, and full protection functions
• Heavy-duty steel base frame with anti-vibration mounts
• Integrated or separate fuel tanks
• Industrial exhaust silencers
• Battery charger and starting batteries
• Optional ATS (Automatic Transfer Switch) and synchronization systems for parallel operation

Dongfeng Cummins generators are known for their low oil consumption, long service intervals, and excellent parts availability through the global Cummins service network. The engines meet relevant emission standards for most markets and offer high reliability with overhaul intervals typically exceeding 15,000–20,000 hours under proper maintenance.

Whether you need a compact 20kVA unit for a telecom site or a robust 250kVA set for factory backup power, Unified Power’s Dongfeng Cummins series provides a complete one-stop solution — from G-drive engine packages to fully assembled open or silent generator sets, control systems, and after-sales support.
