ZICHAI ZDMO550PNOA Generator Set
The ZDMO550PNOA is a high-power, high-reliability diesel generator set, specifically engineered for large vessel propulsion, heavy industrial operations, and emergency power supply scenarios. Built on mature low-speed diesel engine technology and advanced power generation control systems, it delivers efficient and stable power output, providing users with long-lasting, dependable energy solutions.
Advantages of ZICHAI ZDMO550PNOA Generator Set
Delivers a rated power of 550 kW and standby power of 605 kW, paired with the Z8180ZLD-4 diesel engine (661 kW continuous power) at 1500 r/min, reliably meeting heavy industrial and marine high-load demands.
Optimized combustion design achieves a fuel consumption rate of only 195 g/kW·h and a lube oil consumption rate of 1.0 g/kW·h, significantly cutting long-term operating costs while ensuring efficient performance.
Features automatic voltage regulation and a brushless self-excited system, with voltage regulation ratios of ±1% (single unit) and ±2.5% (parallel operation), maintaining stable 50 Hz, 400 V output ideal for sensitive industrial and marine systems.
Rugged 8300 kg construction withstands harsh marine and industrial environments, supporting flexible startup methods (compressed air/electric motor) and 3-phase 4-wire connection for seamless integration into diverse power networks.
