400KW 500KVA Shangchai Open Type Diesel Generator Set with Heavy Duty Engine

This 400KW (500KVA) open-frame diesel generator set is powered by a genuine Shangchai inline six-cylinder heavy-duty turbocharged & after-cooled water-cooled industrial diesel engine, matched with a high-efficiency brushless synchronous alternator. Designed in a classic open-frame structure without a silent canopy, the unit features outstanding natural heat dissipation, rational layout, and easy-access maintenance.

This generator set is widely used in large-scale industrial plants, heavy-manufacturing workshops, factory backup power stations, mine sites, large construction projects, and locations without strict noise-control restrictions. It can work as long-term continuous prime power supply or critical emergency standby power when mains power fails. Complying with ISO8528 and CE international standards, this Shangchai open-frame genset delivers stable heavy-load performance and excellent cost-effectiveness, providing robust power solutions for global heavy-duty industrial and commercial projects.

• Original Shangchai heavy-duty turbocharged & after-cooled industrial diesel engine with massive heavy-industry field verification, sufficient power reserve, strong overload capacity, low vibration and long service life
• Heavy-duty thickened welded steel base frame with reserved mounting holes for foundation fixing; customers can retrofit silent canopy and silencer according to on-site noise requirements
• High-performance brushless alternator equipped with high-precision AVR automatic voltage regulator, ultra-low harmonic distortion and stable voltage output, suitable for various complex heavy-industrial mixed loads
• Complete multi-level protection system: low oil pressure alarm, high coolant temperature shutdown, overspeed, overload, overvoltage, undervoltage and short-circuit automatic protection
• Whole-machine heavy-duty anti-rust and anti-corrosion spraying treatment; H-class insulation and IP23 protection grade, adaptable to harsh indoor and outdoor working conditions
• Open exposed-type structure achieves superior natural heat-dissipation performance. All core components are easily accessible for daily inspection, filter replacement and fault troubleshooting
• Standard 24V DC electric start with heavy-duty maintenance-free battery; optional intelligent controller, ATS automatic transfer switch and remote monitoring module

• Provide 400KW continuous prime power supply and 440KW emergency standby power supply for fixed stations and field heavy-duty operation scenarios
• Real-time monitoring and display of coolant temperature, oil pressure, voltage, current, frequency and cumulative running hours
• Automatic alarm and protective shutdown upon abnormal working parameters to avoid damage to engine and alternator
• Optional ATS automatic transfer switch realizes unattended automatic switching between mains power and generator power supply
• Optional remote start-stop and real-time remote data monitoring function for centralized remote management
• Excellent heat-dissipation performance supports long-time continuous full-load operation under well-ventilated environment
• Allow customers to install external silencer or custom-built silent enclosure to meet local noise-limit regulations

• Well-known domestic Shangchai heavy-duty power brand with abundant heavy-industry project validation, spare parts widely available globally and convenient after-sales support
• Open-frame structure cuts overall procurement cost, offering great cost-performance for large-scale cost-sensitive engineering projects
• Superior natural heat-dissipation capability, effectively reducing overheating risk during long-term full-load operation compared with enclosed silent generator sets
• Exposed component layout simplifies maintenance work, saving time and labor cost for routine inspection and wearing-parts replacement
• Powerful secondary expandability: users can add silencer, silent canopy or container-type housing to satisfy local environmental noise requirements
• Comprehensive multi-layer safety protection system minimizes unexpected faults and extends total service lifespan of the complete unit
• Rich optional configurations: ATS, extended base fuel tank, remote monitoring module, cold-start pre-heating device and generator parallel cabinet for complex project demands
• Every unit passes strict pre-delivery full-load aging test, stable batch quality, suitable for bulk export and large-scale heavy-industry project supporting

Large-scale manufacturing plants, heavy-industry factories, factory backup power stations, mine sites, large construction projects, equipment rooms without strict noise-control requirements, and remote areas without stable grid power supply.
