Your first choice of sup-high cost performance boiler
The new DZH water-fire tube boiler is an eco-friendly and energy-saving product. After 30 years' Research and experiment by professor Li Zhiguang- a famous boiler expert, professor of Harbin Institute of Technology and director of Beijing Institute of Light Boiler. It is a water- fire tube shell boiler, vertical furnace, two-wing flue, and the design of three-pass spirally corrugated tube. Using the unique spirally corrugated tube technology to transfer the heat efficiently. With compact structure, scientific construction technology, precise manufacture, high technical maturity and stable operation, it is well recognized by users after more than 20 years' market experience.
