250KW Silent Type Diesel Generator Set for Commercial Building with Optional Weichai Cummins Yuchai Engine

This 250kW (313kVA) silent-canopy diesel generator set is specially designed as emergency backup power for commercial buildings. It supports three well-known engine brands: Weichai, Cummins and Yuchai for customer selection. Equipped with full-copper brushless alternator and integrated rainproof silent enclosure, the genset complies with ISO 8528 international standards. It provides stable uninterrupted standby power for shopping malls, hotels, office towers, commercial complexes and plaza facilities to avoid business losses caused by unexpected mains power failure.

• Multiple Optional Industrial Diesel Engines: Users can select genuine Weichai / Cummins / Yuchai heavy-duty water-cooled 4-stroke turbocharged intercooled engine. Each power unit features adequate power reserve, low fuel consumption and stable long-hour heavy-load performance. Standard 24V DC electric auto-start system for quick response during power outages, with global spare-parts support network.
• Full-Copper Brushless Synchronous Alternator: Class H insulation, IP23 protection grade, low voltage waveform distortion. Standard 400/230V 3-phase 4-wire 50Hz output (60Hz customizable). Output clean and stable electricity to protect elevators, lighting, air-conditioning systems, fire-control equipment and office precision devices inside commercial buildings against voltage fluctuation damage.
• Commercial-Grade Silent Sound-Proof Canopy: Fully sealed anti-corrosion steel canopy with multi-layer high-density sound-absorbing cotton and large-size industrial silencer. Operating noise ≤73dB(A) @7 m, meeting urban commercial area noise control requirements. Independent air intake and exhaust heat-dissipation duct prevents over-heating under continuous full-load operation, allowing direct outdoor installation without dedicated generator machine room.
• Intelligent Control & Full Safety Protection: Digital controller real-time displays voltage, current, frequency, coolant temperature, lube oil pressure, rotation speed and running hours. Complete protection functions: overspeed, high water temperature, low oil pressure, overvoltage, undervoltage, overload, short-circuit and low fuel level, with sound-light alarm and automatic emergency shutdown. Optional ATS automatic transfer switch realizes fully unattended automatic power switching between grid and generator, which is critical for commercial building backup power system. Remote cloud monitoring module is available for remote status checking and fault alert.
• Reinforced Integrated Base Frame: Thick channel-steel welded base with built-in daily fuel tank. High-density rubber shock absorbers reduce vibration transmission to building structures. Reserved external large-capacity fuel tank interface supports long-time unattended running. Open-frame and mobile trailer structures are available as alternatives.

• Three mainstream well-known engine brand options, flexible to match different budget and after-sales service requirements for commercial projects.
• Optimized silent canopy design meets urban commercial district noise limits for outdoor installation.
• Optional ATS auto-switch function ensures uninterrupted power supply for elevators, fire-safety systems and key commercial loads.
• Stable continuous-running performance, minimizing the risk of unexpected shutdown for commercial building backup application.
• Compact pre-assembled unit, easy hoisting and fast on-site commissioning for commercial project construction schedule.
• Complete fault-protection system improves equipment safety and reduces maintenance workload for property management teams.

Shopping malls, hotels, high-rise office buildings, commercial plazas, mixed-use commercial complexes, large retail centers and other commercial-building projects requiring reliable emergency backup power.
