Main Performance Advantages:
1. Long life span. gas engine is designed and developed through the
cooperation between China Cummins
. Based on Cummins durable engine body, the gas engine life span
reaches 30 years.
2. Long designed overhaul term: 25000 ~ 30000 hours.
3. Total cogeneration efficiency is over 85%, higher than other
China brands by 10%.
4. Four air valves designing for each cylinder. Sufficient air
intaking and exhausting to realize maximum power output.
5. Easy access to spare parts. Based on Cummins engine body, almost
85% parts are made in Cummins factory. it's very convenient to find
any parts at any time and anywhere.
6. Electronic Air/Gas mixer. The mixer guarantees optimum air-fuel
ratio, improves thermal efficiency, reduces NOx emission. Unique
air-fuel ratio adjusting system suits 30% ~ 90% methane density.
7. Ignition system. Altronic ignition system imported from USA
ensures high-precision ignition, which enhances genset life span
and stability.
Alternator Features:
1. World famous brand AC alternator: Leroy Somer, Stamford,
Marathon, ENGGA
2. Brushless, 4 poles, rotation magnet
3. IP21-23(NEMA1) enclose is standard for all industrial
alternators
4. H class insulation system
5. AVR self-regulated, voltage regulation rate: ≤±1%
6. Simple installation and maintenance with easy access to
terminals, rotating diodes and coupling bolts
7. Wide range of flange adaptors and single bearing disc coupling
8. Radio interference restraining accords with the stipulation of
VDE0875-N and ISO8528
9. Moisture proof, sand-proof, dustproof, salt-proof and
vibration-proof
