Shangchai Silent 3 Phase 250KW Diesel Generator Set With Weather Resistant Canopy
This 250kW (312.5kVA) silent diesel genset is driven by original Shangchai heavy-duty industrial diesel engine, matched with high-efficiency brushless synchronous alternator. Equipped with heavy-duty weather-proof silent canopy, it effectively cuts operating noise and supports direct outdoor installation. It can work as prime power or emergency standby power source. Widely used in hospitals, commercial complexes, residential districts, large construction sites and other locations with strict noise-control requirements. Optimized independent air-duct design ensures stable heat dissipation under long-time full-load continuous operation.
