Heat Exchanger Products


Thermal control technology utilizing heat exchangers is indispensable for our daily life since it is used in various fields of industry and society, such as aircrafts, iron works, semiconductor manufacturing plants, LNG bases, railcars, fuel cells, just to name a few. In response to customers' needs in Japan and abroad, Sumisho Metalex provides solutions for heat exchangers and their peripheral devices.

Main Products

Heat Exchangers for Industrial Gas and LNG Plants

For the industrial gas, heat exchangers are widely used in many places including metal refining plants, chemical plants, food-processing plants and semiconductor manufacturing plants. In LNG plants, heat exchangers are required to liquify and vaporize natural gas, which is nowadays an indispensable energy source for our community and industries. In the industrial fields, Sumisho Metalex supplies products of high quality as well as high reliability, and has been expanding its business worldwide.

Heat Exchangers for Fuel Cells and Cogeneration

Fuel cells derived from hydrogen and oxygen are a power generating system for the next generation. Cogeneration system utilizing exhaust heat is a power generating system to enhance energy efficiency. Both systems are recently attracting attention as environment-friendly. Within and outside of Japan, Sumisho Metalex extensively handles small-size stainless heat exchangers with high heat resistance and high efficiency.
