Screw refrigeration compressor industry in China's development since 1980s started, in 90s the rapid growth with the rapid development of the domestic commercial central air-conditioning market, screw compressor production enterprises have by world-renowned products imported, corporate mergers, joint ventures, set up subsidiaries and other ways to enter the market China, screw compressor market brand concentration began to increase gradually the Pitzer of Germany, Italy, Taiwan and refcomp Fusheng Han Zhong Seiki four foreign-funded enterprises as the leading market pattern.
Pitzer: Germany is a multinational group of compressor production history of 70 years, the main products of semi hermetic compressor has a worldwide reputation for quality performance class, for many years in the world has occupied the largest market share. The last century in 90s, Pitzer began to enter the Chinese market, established in 1994 in Beijing Pitzer refrigeration equipment Co. Ltd., Pitzer in Germany in 2001 Chinese a wholly owned subsidiary of Pitzer compressor (Beijing) Co. Ltd. was established. In recent years, Pitzer began to get involved in the screw compressor, screw compressor production reached a new level in technology and performance, its compact design, light weight, low cost, economic operation when the cooling capacity and COP are very high. Due to the adoption of the patented lubrication system and the large size bearing screw compressor, the utility model has the advantages of reliable operation, and is especially suitable for parallel operation, and can be connected in parallel to six. .
Italy refcomp: founded in 1991, mainly engaged in the production and supply of compact type compressor and piston type screw compressor advanced technology in the world, and provide excellent solutions for high-tech refrigeration system. The input power of screw compressor is the production of the minimum specifications for 30Hp, the maximum input power specifications of up to 390Hp, with the complete series and complete specifications, is a global leader in the production of screw compressor. In April 2005, refcomp established their own factories in Italy: China refcomp compressor (Shanghai) Co. Ltd., the factory is located in Shanghai Zhangjiang High Tech Park of Pudong District, covers an area of 10000 square meters.
Taiwan Fu Sheng: founded in 1953, is a professional manufacturer of multinational compressor. Fu Sheng screw refrigeration compressor rotor adopts imported special processing machine and imported precision grinding machine for processing rotor rotor, with the 5:6 patent new rotor tooth type, high efficiency of the Europe and the United States well-known European motor, high precision bearings, and through strict quality test. Has won the "American National Laboratory Certification UL, CEmark certification EU safety regulations", "the EU pressure vessel PED certification, ISO9001 international quality certification", "CRAA certification" and a number of domestic and international product certification and quality certification.
Shanghai Hanbell Seiki: is an independent supplier of domestic screw type air conditioning refrigeration compressor is one of the world's largest market, manufacturing service providers is the world's few focus on the design and manufacture of screw compressor. Hanbell screw compressor is dominant in the domestic air-conditioning market, annual sales accounted for more than the domestic air-conditioning screw compressor market 60% of the total, Haier, GREE, Midea, Tsinghua Tongfang, Shuangliang, Nanjing refrigerator factory in Dalian, and other large icebergs and commercial central air conditioning production plant long-term supplier. Han Zhong Seiki 2008 listed in A share.
Compared with Han Zhong Seiki screw machine screw machine manufacturing enterprises mainly has the following advantages:
(1) the local business advantage. Is currently the highest degree of localization of the operation of screw compressor enterprises, in addition to the rotor outside most parts have been purchased to achieve localization of production, while the rotor will also realize the localization of production in recent years.
(2) sales and service channel advantage. Is the main manufacturer of screw refrigeration compressor, the only direct sales model of enterprises.
(3) professional advantages. Is the only one focused on screw compressor product development, manufacturing and sales of enterprises, from 90kw to 1465kw models of the most complete screw compressor products, a higher level of specialization.
(4) technical advantages. The application of screw compressor technology in different working medium, such as air, vacuum, refrigerant, special gas, etc., has become the world's largest screw compressor manufacturer. With the technical ability of motor optimization design, the integrated use of intelligent control technology and frequency conversion energy-saving technology to the field of screw compressor, screw compressor has developed the frequency characteristics of energy saving, in the forefront of the development of global technology.
