10-50KW Diesel Generator Set With Cummins Engine

This series of small-power diesel generator sets powered by Cummins covers a prime power range of 10-50kW and a standby power range of 12.5-63kVA. The core power is equipped with Cummins' classic B-series engines (representative models: 4B3.9-G11, 4B3.9-G2), which are high-reliability power supply solutions specially designed for global small-scale power demand scenarios. The generator sets are designed and manufactured in accordance with international standards such as ISO8528-2005 and GB/T2820-2009, fully complying with international emission requirements like EPA Tier 4 and EU Stage V, and meeting the access standards of major global markets including Europe, America, Southeast Asia, and Africa.

The whole machine supports multiple installation methods such as wall mounting, ground fixing, and trailer movement. With an ultra-low fuel consumption rate of 216g/kW·h, a major overhaul cycle of 6000 hours, and the ability to start quickly at ultra-low temperatures of minus 30°C, it can be widely used to meet the needs of various working conditions such as backup power supply and small-scale constant load. It is the preferred power equipment for overseas small-scale commercial, agricultural, outdoor construction and other scenarios.

Core Selling Points

• Original Cummins power, extremely reliable and durable

  It is equipped with a Cummins 4B3.9 series inline 4-cylinder engine, featuring a forged steel camshaft, a high-strength alloy cast iron cylinder block, and a platform cross-hatch honed cylinder liner design. This effectively prevents oil leakage and offers excellent high-pressure resistance and impact resistance. It is equipped with a Holset exhaust gas bypass valve and a rotor high-pressure fuel pump, ensuring stable power output and sufficient fuel atomization. The fuel consumption rate is as low as 216g/kW·h under 100% load, balancing power and fuel efficiency.

• Adaptability to all working conditions, unaffected by extreme conditions

  Optimized design for climate characteristics of different global regions: It can start quickly within 5 seconds in a low-temperature environment of -30℃, meeting the needs of cold regions such as Northern Europe and Central Asia; the closed water circulation cooling system combined with a high-efficiency radiator enables continuous and stable operation in a high-temperature environment of 45℃, suitable for high-temperature regions such as the Middle East and Africa; the overall protection level reaches IP23, with moisture-proof, dust-proof and salt spray-proof capabilities, applicable to humid working conditions in coastal areas of Southeast Asia and mining dust environments.

• Compact and flexible design, easy to install, operate and maintain

  It adopts an integrated "one-piece multi-functional" structure, eliminating redundant connectors. The minimum size of the unit is only 1800×800×1200mm, which can be directly embedded in a small machine room or wall-mounted, greatly saving space. The accessories are universally used worldwide and easy to obtain, and the maintenance cost is 30% lower than that of similar products. It supports DC24V maintenance-free lead-acid battery electric start, with a simple operation process, and start-stop operations can be completed without professional personnel.

• Precise power control + multiple protections for worry-free power supply safety

  It is equipped with a Stanford brushless three-phase AC synchronous generator and an AVR automatic voltage regulation system. The steady-state electricity \(Compression adjustment rate ≤\pm 1 \%\), \(Voltage fluctuation rate ≤0.5 \%\) can accurately adapt to loads with strict requirements on power supply quality, such as precision instruments, medical equipment, and small production lines. It has a built-in intelligent control system, integrating five protection functions: low oil pressure, high water temperature, overload, undervoltage, and phase loss, which can automatically alarm and emergency stop; it supports the ATS automatic switching device, which can complete the power supply switching within 15 seconds after the mains power is interrupted, realizing unattended operation.

• Complete international certifications for unimpeded access to global markets

  The entire series has obtained authoritative certifications such as CE, ISO9001, EPA Tier 4, and EU Stage V, allowing access to mainstream European and American markets without additional modifications. It meets the import standards of emerging markets such as Southeast Asia and Africa, with convenient customs clearance procedures. A 1-year or 1000 operating hours warranty for the entire machine is provided, covering core components of the engine, generator, and control system.
