Effectively utilize exhaust heat to reduce fuel consumption!!
Releasing boiler exhaust heat directly into the atmosphere wastes thermal energy. The exhaust heat recovery heat exchanger "SK Economizer," when installed on a boiler, efficiently recovers the heat from combustion exhaust gases to preheat the feedwater for the boiler, thereby improving boiler efficiency and reducing fuel consumption, contributing to energy savings. Additionally, depending on the heat transfer area, it may comply with boiler structural standards. "Narikawa Industrial," which manufactures heat exchangers, has obtained boiler manufacturing permission, allowing for a wide range of proposals. 【Specifications】 ○ Function: Exhaust heat recovery ○ Heat medium: Water ○ Element materials: - Tubes: Steel pipe (STB), stainless steel pipe (SUS-TB) - Fins: Steel fins (SPCC), stainless steel fins For more details, please contact us.

Company information
We design and manufacture heat exchangers for industrial machinery and heaters/coolers for air conditioning. Sakai River Industries' 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 (plate fin, aero fin), shell and tube types and plate types for liquid-liquid, and gas-gas types. Additionally, we own our own performance testing equipment and are engaged in research and development of thermal technologies 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 Industries is always striving for technological innovation, working hard to ensure that our customers can confidently use heat exchangers that are truly beneficial to them.
