About us:Our factory were established in the early 1950' s and have more than 60 years of machinery production experience. Our product ranges from diesel engines, gas engine, generator sets.
We have 7 scientific research centers where our products are designed. In our production centers we use specialized casting, machining, pressing and assembly machines, 12 production lines and more than 1, 000 other units of equipment. This collection helps us to achieve a capacity of 200000 engines, 150000 generator sets annually.
Our engines include three series which feature more than 300 varieties with power ratings varying from 20 to 660kW. You can select from diesel, gas or other fuel-powered options. We have turbo-charged models, with or without a cooler, altiplano models and models that use European technology. The latter reaches new standards in terms of dynamics, durability, low emissions and economical savings. These engines are used in agricultural equipemnt, generator set, ship, pump, air compressor and construction machinery and so on.
Our generator sets series include internal combustion engines and dynamotors that range from 5 to 1, 000KW. We offer automated units, mobile power stations, gas generator sets and more. The noise level for low-noise gensets can reach 60dB at 1M. Our generators are used in industry, standby power in hospital, malls and hotels, telecom
