Vortex Hot-film Heat Exchanger is our company’s new innovation. Its 20-year service life instantly attracted the attention of the experts and customers. After being used in various places in China, customers uniformly confirm that the product is a heat exchanger with the highest performance and price ratio. Now, the product has been rewarded national monopoly by State Intellectual Property Office. (Patent No.: 02268208.2).The innovation of Vortex Hot-film Heat Exchanger dose not only lies in the changing of heat exchange tubes, what’s more important, completely considering the circulating relationship among the heat exchange tubes, heat exchange tubes and body case, it never compelled out the turbulent flow by using baffle board to block off. Instead, it forms alternative vortex flow by naturally induction among the heat exchange tubes, and ensures the heat exchange tubes maintain the vibration force under the premise of without friction. It realizes the longtime, high efficient and stable operation of heat exchanger. Main characteristics: 1: High efficiency and energy saving, with heat transfer coefficient of 2000~3000W/m2.oC; 2: It is made of full stainless steel with a long service life over 20 years; 3: Turbulent flow, instead of laminar flow, improves heat exchange efficiency and lowers thermal resistance; ;4: Rapid heat exchange, high temperature （400 oC）resistance and high pressure（2.5MPa）resistance; 5: Compact structure, small space requirement, light weight, convenient installation and less investment in civil construction; 6: Flexible design, a full range of specs, pragmatic and less cost; 7: Wide applications - applicable to a wide range of pressures, temperatures and heat exchange media; 8: Low maintenance cost, easy operation, longer scale-removing interval and convenient cleaning; 9: Nano-film technology significantly improves heat transfer coefficient; 10:Wide applications, including thermal-electric plants, mines and factories, petroleum and chemical sector, buildings’ heat supply, domestic hot water, food and pharmacy sector, energy and electronics sector, machinery, light industries, etc.
