Since early 1980’s, our board chairman, Mr.Zhanglongyi, with his men started to study and manufacture oil purification and treatment equipment.

In 1993, Chongqing Huaneng Oil Purifier Co.,Ltd was founded. Through continuous innovation and pursuits, Huaneng quickly made a name for itself in national market and became as a designated oil purifier supplier to Chinese State Electric Power Corporation.

In 2000, Huaneng became the 1st one in China, which is given the right to export oil purifier to foreign market. Our ZLY SERIES, used/waste engine oil purification equipment, is pioneer product in China, which solves the worldwide gas engine oil-recycling problem.

In 2005, we changed into Chongqing QIANNENG Industry Group Co.,Ltd for multiple development, now we dealt in oil Purifier manufacture, fuel gas supply and real estate management. 

Nowadays we are one of China's largest oil purifier production base, our chairman is called by Chinese media” the magnate of Chinese oil filters”.
