※　Zhong Nan Hai Heating Engineering　※

　　In 1999, the Zhong Nan Hai applied a ready-to-use corrugated tube heat exchanger to replace to the four formal heat exchangers. Under the same water condition, the equipment place was reduced to the 1/3 of original one. The investment is saved for more than half of the former one The dirt and leakage problems were completely solved. This is one of our application cases.

　　More and 2000 of our corrugated tube heat exchanger are applied in the field of central heating, city heating and daily water heating in above 20 cities around China. The Zhong Nan Hai, People's congress, Shangri-La Hotel, Peking Hotel, 301 Hospital, 304 Hospital, PLA College of Arts and Mei Chu Group are all our users.
