Recently, Mr. Lu Yawei, the head of Jiangsu Yanruilin Precision Machinery Co., Ltd., led a technical team to Zhejiang to visit Zhejiang DunAn Artificial Environment Co., Ltd. The two sides conducted in-depth exchanges on the application of tube end rounding machines in the fields of refrigeration accessories and copper tube processing, and officially reached a cooperation intention.
Zhejiang Dunan Artificial Environment Co., Ltd. (Stock Code: 002011) is a core refrigeration components enterprise under Gree Group. In 2022, Zhuhai Gree Electric Appliances acquired a controlling stake in Dunan Environment, becoming its major shareholder. As a globally leading manufacturer of refrigeration components, Dunan Environment mainly produces four-way reversing valves, electronic expansion valves, stop valves, piping components, and other refrigeration control components. Its products are widely used in household air conditioners, commercial air conditioners, heat pumps, and thermal management for new energy vehicles. The company is a core supplier to major global air conditioning manufacturers such as Gree and Midea, enjoying a high reputation in the global refrigeration components industry.
During the meeting, Mr. Lu Yawei and his delegation conducted an on-site visit to DunAn Environmental's production facilities, gaining a detailed understanding of its stringent requirements for tube end roundness, consistency, and production efficiency in the processing of refrigeration pipeline components. The DunAn Environmental technical team acknowledged the capabilities of the Yanrui tube end rolling machine in copper tube end rounding, deburring, and ensuring sealing and assembly accuracy.
Both parties unanimously agree that with the rapid growth of heat pump and new energy vehicle thermal management businesses, DunAn Environment's demand for high-performance pipe end processing equipment continues to increase, and there is broad scope for cooperation. The two parties have reached a preliminary cooperation intention regarding the equipment configuration, process verification, delivery schedule, and subsequent batch cooperation of the pipe end rounding machine.
The conclusion of this cooperation intention signifies that the equipment and services of Yanruilin Precision Machinery have been recognized by the enterprise system of Gree Group. In the future, Yanruilin will continue to focus on the fields of tube-end forming and tube-end rounding equipment, using high-precision, highly stable equipment and fast-response services to help Dunan Environment and more customers in refrigeration, heat exchange, automotive, and other industries improve their pipeline processing capabilities.
