In 2004, we successfully developed a product with independent intellectual property rights — the integrated extrusion finned tube. The introduction of this component resulted in 2 separate patents. In the final quarter of this eventful year, we once again set the precedent by officially unveiling the first domestic finned tube coil heat exchanger in a joint project with the HANGYANG Group, a leading oxygen generator manufacturer in China. This newly developed component was implemented for trial purposes by a HBIS facility in Handan city. Its performance was actively tracked and monitored by the HANGYANG Group for several months and finally declared as a success. A long-term cooperative relationship was forged between our companies after this intensive collaborative effort. As their designated supplier we provide high finned tubes for matching heat exchangers, effectively optimizing the air separation unit of their cooling system. These state-of-the-art cooling solutions are either exported or sold to domestic giants in the steel industry, e.g., the BAOSTEEL Group, the ANGANG Group, and Wuhan Iron & Steel.
Our product can be applicable to the solar water heater, thermal storage tank, and so on. Replacing the heat exchange pipes in the heat storage devices with our finned tube can greatly enhance the energy transfer efficiency. For example, if we add our product in the solar water heater, the heat in thermal storage tank will be utilized sufficiently. The output water can be used to drink, wash and cook, to achieve the goal of environment protection. In China, the market size of solar water heater is about CNY 40 billion which is also no doubt a big market for our product.
