our story


Creation and early growth

In the fall of 1988, our founder, gospatin Zhang Guoping, was invited by the government of the town’s Choutie to jointly build a boiler plant, which later became a specialized boiler manufacturer with 80 personnel and an annual turnover of 37 million Chinese yuan in 2004.


Continuing investment and business expansion

LLC “Zozen Kotel” further increased investment in equipment, expanded production areas and introduced new technologies in subsequent years. In 2011, with an annual turnover of 300 million RMB and 20 patents on its behalf, Zozen Kotel LLC became the top brand in the Chinese boiler market; but we didn’t stop there


A look into the future

LLC “Zozen Kotel” carried out 80% of production automation in 2017. Now we have 400 personnel and 59 patents, the annual turnover has reached 600 million Chinese yuan. “ZOZEN”, being one of the leading suppliers of boiler equipment in China, now seeks to serve the global market.
