ABOUT US Current position: Home > Company Introduction
  Zhengjiang Zhefeng Electromechanical Equipment CO.,LTD(hereinafter referred as Zhefeng) is located in Shangyu, a place where a famous Chinese tale “rise again in Dongshan Mountain” happened。Zhefeng is conveniently situated next to Hangzhou-Ningbo Express and Shangyu-Sanmen Express, about 90 kilometers far away from Hangzhou and Ningbo.Zhefeng ,covering an area of 30989 square meters of which 21000 square meters are building area, manufactures fans、forced air cooling systems、air conditioning ventilation equipments. Zhefeng has all sorts of manufacturing and sophisticated te' ;%ވZh8HE' ;%ވZhbeen cooperating very well with Zhejiang University 、Tongji University and other power designing facilities for many years, committing ourselves to developing hi-tech ventilations and air cooling equipments."Zhefeng"brand explosion-proof roof fan, rain-proof shutter, explosion-proof centrifugal fan, explosion-proof axial flow fan, explosion-proof natural ventilation, explosion-proof induced fan—the results of our cooperation-have been tested qualified in accordance with GB3826.1-2000 the first part of Electrical apparatus under explosive gas environment: General requirements and GB3826.2-2000 the second part of Electrical apparatus under explosive gas environment: flameproof D by National explosion-proof electrical product quality supervision and Inspection Center and Shanghai explosion-proof electrical product testing station of Coal industry, and have been awarded with the certificate of explosion proof products and the explosion proof products production license. The technique we used in energy-saving explosion proof fan, rainproof shutter and auto rainproof product has been awarded as the utility national patent by national administration of intellectual properties. GPF fire high-temperature exhaust fan was awarded with golden prize and high tech honorable prize in1998’s spark invention contest hold by national fire equipments quality testing center, known for its low vibration and high efficiency and acquired the certificate of China top brand. Zhefeng had passed qualified in accordance with quality managements by the ministry of Agriculture, was certified by ISO 9001 and was awarded with role model company and contract and accredit honoring company by Shangyu government for many times.

   Zhefeng mainly manufactures industrial ventilations and civil fire smoke exhaust equipments. Industrial ventilations includes roof fan, aluminum alloy rainproof shutter, axial flow fan, roof natural ventilation, jet induced device, cooling tower, air conditioning device and electrostatic precipitator. These products could be used for ventilation and air cooling in workshop and railway tunnels, mostly in power, metallurgy, machinery, pharmacy industries. Our products are well known for high wind, low noise, low vibration, good wind proof, great energy saving, high-efficient in ventilation, safe and explosion proof, reliable run.The electricity driven rainproof shutter has firstly used the stainless steel ball bearing drive in China, thus making the product have long life, flexible rotation, good ventilation. This product, tested qualified by Environmental Science and Engineering collage of Donghua University, has been the most advanced among domestic counterparts. These products have been widely used in Zhejiang Jiangxin 3rd powe company, Guodian Taizhou Power Generation company, Guodian Zhejiang Beilun 3rd power company,Shanghai Caojing power plant, Guangdong Pinghai power plant, Guodian Jianbi power company, Fujian Fuqing nuclear power plant, Guodian Changzhou Power Company, Jiangsu Zhenjiang power company, Guodian Gold Budian power company, Datang Ningde power company, Hubei Ezhou power plant, Henan Minquan power plant, Shenyang Jinbei Automobile Factory, Beijing Automobile Works, Yangzi Petrochemical, Luoyang Petrochemical and other large state key projects.

   Civil fire exhaust and ventilation covers all ranges. Fire axial exhaust fan, fire cabinet centrifugal exhaust fan, roof exhaust fan fire, smoke dampers, fire dampers, nonflammable type wind pipe products have passed the National Fire Equipment Quality Supervision and Inspection Center and the National fixed fire extinguishing system and fire Component quality supervision and Inspection Center of qualified test.

   Such products have good production technology under great quality system in strict accordance with ISO9002 quality assurance system. The fan outer cylinder flange have used one-step forming with mechanical flanging, fan impeller also used one-step forming with mechanical hydraulic pressure. These products have enough intensity, smooth appearance, high concentricity, balance, high precision, low vibration, etc and have been widely used in a number of great key projects including Hangzhou Huanglong Square, Hangzhou Shangri-la Hotel, Beijing Asian Games Village, Beijing Sichuan Mansion, Shenyang Taoxian International Airport, Guangzhou Railway, Zhuhai International Airport, Fuzhou International Airport, Guangzhou Wangfujing Department Store, China air to air missile base, Dalian Bohai Mansion, Wuxi Yaohan Shopping Mall, being widely praised for its great quality and fine service.
