The coil-wound heat exchanger (CWHE) is a kind of special shell-and tube heat exchanger. Since it was applied in the industry in 1895, it was widely used in the industries such as coal chemical industry, fertilizer, fine chemical industry, pharmacy and energy conservation and environment protection. It is also being continuously popularized and widely applied. The coil-wound heat exchanger can be made of many materials such as copper, aluminum alloy, stainless steel, carbon steel, dual-phase steel and titanium so as to be adapt to the requirements for different work environment (including greater temperature gradient, higher pressure and better corrosion resistance). Our products meet GB, ASME, CE, EAC or other standards as requested.
