Anhui Guangde towards the Electrical and Mechanical Co., Ltd. is located in Guangde Economic and Technological Industrial Park, Anhui, Zhejiang and Jiangsu provinces at the junction, geographic location. The company from Hangzhou, Hefei, Nanjing, capital is only two hours away. In Central, East provides a convenient excellent service and product sales. Anhui Wannan is the largest-scale production of ventilation technology enterprises. This is a company specializing in research, development, design, manufacture high-tech enterprises, high-temperature fire fans supporting motor production technology enterprises, the production of exhaust valves, fire dampers, muffler, HIP me, and other ventilation equipment in the field of backbone enterprises. Ventilation equipment has many years of design and manufacturing experience, through continuous efforts, through continuous development and introduction of advanced products, has successfully broadened the scope of fans and other products, it is already the country with a certain amount of professional ventilation equipment manufacturers. The company specializes in producing low-noise cabinet centrifugal fan, low-noise wind chassis, duct fans, fire temperature exhaust fan, mixed (oblique) flow fan, square wall fans, axial roof fans, centrifugal roof fan, induced fan, jet fan, subway wind magnesium composite duct, fan and valves and other fire products through the National Fire Equipment Quality Supervision and Inspection Center. Companies with new product development, improve their core competitiveness; quality of survival, and constantly create performance height; in energy efficient, take sustainable development strategy goals. R & D products using CFD and CAD software to simulate the fan, flow field analysis to obtain a more excellent performance products. Companies "advanced technology, improve the detection, inspection norms", enhanced product control standards; and require the company product standards higher than the national or industry standards. Fans of traditional technology is relatively backward, the company mold parts, operation mechanization and become an advanced enterprise in the ventilation industry. In this "sincerity towards fans" Special thanks in product development, design process have been Fluid Machinery Research Institute, Xi'an Jiaotong University, Zhejiang University School of fluid associated Machinery Research Institute, Shanghai Jiaotong University School of dynamic and active, Shanghai Jiaotong University School of Telecommunication Department of Automation, etc. Technical support and exchange of school and experts, improve product efficiency, energy saving, low noise performance and fan-controlled device implementation and optimization system for the user to make some contribution to energy saving and emission reduction units. Good customer service and user visit system, improve the technical service system, so that customers feel towards Cheng Fan brand concept. Sincerity towards fans, the times, and sincerely welcome friends to visit study guide!
