In the field of nuclear power, after years of technological research, the Company has broken the foreign technological blockade and technological monopoly on the HVAC system equipment for the nuclear island of the megawatt-class units, developed the HVAC system equipment for the nuclear island of the megawatt-class pressurized water reactor (PWR) nuclear power plant and successfully applied it to the second phase of the Ling'ao Nuclear Power Station, and become the only manufacturer that has mastered the key technology of the HVAC system equipment for the nuclear island of the megawatt-class PWR nuclear power plant and has the experience of general contracting. It has become the only manufacturer in China that has mastered the key technology of HVAC system equipment for nuclear islands in MWe pressurized water reactor nuclear power plants and has experience in general contracting. At present, the company has applied to the State Patent Bureau for 4 patents of invention and 4 patents of utility model for the HVAC system related equipment of nuclear island of MWe pressurized water reactor nuclear power plant. As of June 30, 2009, the Company has become the general contracting supplier of HVAC system equipment for the nuclear islands of Guangdong Ling'ao Nuclear Power Plant Phase II (2*1 million kilowatts), Liaoning Hongyanhe Nuclear Power Plant Phase I Project Unit 1, 2, 3, 4 (4*1 million kilowatts), Fujian Ningde Nuclear Power Plant Project Unit 1, 2, 3, 4 (4*1 million kilowatts), and Yangjiang Nuclear Power Plant Phase I, Unit 1 and 2 (2*1 million kilowatts). Supplier. According to the "China Ventilation and Air Treatment Industry Research Report", from 2004 to June 30, 2009, the Company's market share in the HVAC system equipment for nuclear islands of nuclear power plants in China was 72.44%, of which the market share in the HVAC system equipment for nuclear islands of nuclear power plants with megawatt-class and above units was 77.50%. As of the date of this prospectus, the Company is the only enterprise in the domestic ventilation and air treatment industry to have obtained a license for the design and manufacture of nuclear-grade fan products issued by the National Nuclear Safety Administration (NNSA) and one of the four enterprises to have obtained a license for the design and manufacture of nuclear-grade damper products issued by the NNSA.
In the field of subway, our company designs and develops the subway ventilation and environment control system with the help of CFD, and develops the subway ventilation and air treatment system products with high flow rate, high pressure, high efficiency and low noise, and all the performance indexes of the products meet or exceed the national standards and reach the international leading level in the same period. Among them, the innovation project of NXT direct-fired high-temperature fire exhaust axial fan passed the acceptance of the Technology Innovation Foundation of the Ministry of Science and Technology of the People's Republic of China, and the product was recognized as a national key new product. The Company's breakthrough in ventilation and air treatment equipment in the field of subway has changed the situation of domestic subway ventilation and air treatment equipment relying on imports. As of June 30, 2009, the Company's ventilation and air treatment equipment in the subway field has been successfully applied in Guangzhou Metro Lines 2, 3, 4, 5 and 8, Shenzhen Metro Line 3, Tianjin Metro Line 2 and Chengdu Metro Line 1. According to the "China Ventilation and Air Treatment Industry Research Report", as of June 30, 2009, the total length of metro lines that have been completed and are under construction and have completed the bidding of ventilation equipment is about 920 kilometers. Among them, the kilometers of metro lines for which the Company provided ventilation equipment amounted to 298 kilometers. Calculated by the number of kilometers, as of June 30, 2009, the Company's domestic market share in the field of subway ventilation equipment is 32.39%, ranking the top two in the field of subway ventilation equipment.
In the field of highway tunnels, the Company is the first to develop large-scale movable-blade adjustable axial fans for highway tunnels in China, which saves about 10% of electricity consumption compared with ordinary products and has been successfully applied in the ventilation system of the world's longest two-way tunnel in the Qinling Mountain, Zhongshan Mountain. According to China Ventilation and Air Treatment Industry Research Report, from 2006 to 2008, the Company's market share of ventilation equipment for long tunnels over 5 kilometers was 18.15%, the top three in the tunnel field.
