We design and manufacture heat exchangers for industrial machinery and air conditioning. Sakai River Industry's heat exchangers are used in the production processes of various industrial products. They are widely adopted not only as heat exchangers for industrial machinery but also for cooling and air conditioning equipment. We offer a variety of heat exchangers, including finned tube types for liquid-gas applications (plate fin, elofin), shell and tube types and plate types for liquid-liquid applications, and gas-gas types. Additionally, we own our own performance testing equipment and are engaged in research and development of thermal technology aimed at improving the efficiency and compactness of heat exchangers. Utilizing our uniquely developed performance calculation system, we can promptly propose heat exchangers with specifications that best meet our customers' needs. We continue to produce high-quality heat exchangers with reliable technology and a consistent production system. Sakai River Industry is always striving for technological innovation, working hard to ensure that our customers can confidently use heat exchangers that are truly beneficial to them.
