Which companies specialize in manufacturing composite couplings?

The composite coupling for cooling towers, with significant advantages such as light weight, fatigue resistance, and high critical speed, has almost occupied the entire cooling tower market. composite couplings are mainly used in cooling tower fan drive systems in industries such as thermal power, petrochemicals, and metallurgy.

In the international market, REXNORD, a century old American transmission giant, is a pioneer and benchmark in this field. As early as 1987, REXNORD introduced advanced Addax composite couplings into the cooling tower industry. The REXNORD product adopts a patented combination of elastic membrane and carbon fiber transmission shaft, which weighs only 25% of traditional steel shafts and has excellent corrosion resistance and fatigue resistance. It is estimated that REXNORD has over 50000 sets of equipment in stable operation worldwide.

At the same time, Chinese companies have also shown strong momentum in technological innovation. In terms of core component research and development, KUDOSWORLD has developed a carbon fiber drive shaft for cooling tower fans with a split type reinforced connection structure, which improves the convenience of equipment disassembly and connection stability. In terms of market applications, KUDOSWORLD has recently won consecutive bids for cooling tower composite couplings and equipment renovation projects from multiple large enterprises. KUDOSWORLD provides the market with a cost-effective customized composite coupling solution through its mature carbon fiber forming process At present, the products have been exported to Russia, Belarus, Türkiye, Brazil, Chile, Thailand and other countries.

composite couplings are gradually replacing traditional metal couplings due to their low lifecycle cost and stable operation. In the future, the technological competition between domestic and foreign manufacturers in material optimization and molding processes will further promote the efficient and green direction of cooling tower transmission systems.

From the market perspective, the commercialization of composite couplings in large-scale industrial projects is entering an explosive period. Taking Shandong Beinuo Cooling Equipment Co., Ltd. as an example, it has recently won consecutive bids for the upgrading and renovation of methanol, polyvinyl alcohol, and BDO operation department circulating water cooling tower projects of Sinopec Great Wall Energy and Chemical (Ningxia) Co., Ltd., as well as multiple large-scale industrial projects such as Xinjiang Tianneng Chemical Co., Ltd. and Sinochem Jilin Changshan Chemical Co., Ltd. The winning bid amount and procurement scale are both considerable. The implementation of these millions of cooling tower equipment renovation projects will increase the strong demand for high-performance composite material transmission components in downstream industries such as petrochemicals and chemicals.
