Founding and early growth

In the fall of 1988, our founder, Mr. Zhang guoping, was invited by the government of Zhoutie Town to build a boiler plant, which later grew into a specialized boiler producer having 80 employees and an annual turnover of RMB 37 million in 2004.

Continued investment and expanded business

ZOZEN further increased its investment in equipment, expanded its manufacturing space and introduced new technologies in the years that followed. In 2011, with an annual turnover of RMB 300 million and 20 patents in its name, ZOZEN became a top brand in China’s boiler market; but we did not stop there.

Looking into the future

ZOZEN saw 80% of its manufacturing automated in 2017. We now have 400 employees and 59 patents, and our annual turnover has reached RMB 600 million. Being one of China's top boiler suppliers, ZOZEN is now looking to serve a global market.
