[Thermal energy recovery] High efficiency heat exchangers effective for exhaust heat recovery
Because of their high efficiency, plate-fin heat exchangers allow heat to be exchanged between two fluids at temperatures close to each other (gas-to-gas or gas-to-liquid), making them adequately work as heaters or coolers.
For example, the process as indicated in the following "Sumitomo Precision's heat exchangers could do …" is feasible.
Excess thermal energy can be returned to the boiler to generate additional electricity, contributing to a reduction in running cost of the plant equipment.


Achievement of [downsizing, lightweighting, and high performance]
High efficiency represents heat exchangers lighter in weight and smaller in size as compared with other types of heat exchangers.


[Compliant with a broad range of regulations] Certified by domestic and overseas engineering regulations
・Domestic regulations: Electric Utility Industry Law, various High Pressure Gas Safety Acts, Occupational Safety and Health Act (class-1 and class-2 pressure vessels, small-sized boilers, and simplified boilers*)
     *Only for stainless-steel heat exchangers for high-temperature applications

・Overseas regulations: ASME in the U.S., PED in Europe, Manufacture License in China, and Manufacture Registration in Korea


[Vibration resistance] Applicable to Shinkansen and special-purpose vehicles
・Plate-fin heat exchangers, which are used for Shinkansen, conventional railroad vehicles, and special-purpose vehicles, can be mounted on systems being subjected to frequent vibration.
