PML Diesel Generators with Standby Power 880 — 3250 kVA are vastly used in transportation sector, buildings, telecom, schools, hospitals, ships, oil fields and industrial power supplying area etc, which can be applied as main power or backup generator/standby generator/emergency generator.
MTU diesel engines featuring with low fuel consumption, long service intervals and low emissions.
Main Characteristics Of Generators
- Reasonable structure design, modular structure design and convenience in maintenance
- Strong adaptability of engine, no need of power correctio at the altitude of 400 m when the environment temperature reaches 40 ° C; excellent engine load response
- Extremely excellent fuel economy, low fuel consumption and oil consumption, and the indicators can reach 190 ~ 200 g/Kwh, with a low operating cost
- Excellent exhaust emissions targets, NOx value <2000mg /m;Low particle emissions, to meet all emission standards
- A long interval of overhaul, up to 24000 hours.(note:general domestic units for 8,000 hours, Japanese American units for 12,000 hours)
- Intervals of oil change for high quality oil is up to 1000 hours, being able to run 24 hours
- No smoke phenomenon during the start-up;low noise, low vibration;good indexes in volume-to-power and weight-to-power
- Electronic management system with the function of self-diagnosis
