High temperature heat exchanger

In response to the need for highly efficient, compact heat exchangers that can be used in high-temperature and corrosive environments, we also manufacture stainless steel plate-fin heat exchangers. These are used in fields that require high durability, such as fuel cells, cogeneration, ultra-high-purity gas production equipment, and regenerators for gas turbines used in power generation. We also offer titanium plate-fin heat exchangers for use in severely corrosive environments such as seawater.
To meet advanced specifications, we offer a range of products with excellent functionality and structure, and are expanding the range of applications to include fields with higher temperatures and more severe operating conditions.

LNG Vaporizer

Natural gas has become an essential energy source for industry and society. Natural gas is cooled to ultra-low temperatures and transported to remote locations by tanker as a liquid, known as LNG (liquefied natural gas). However, to be used as fuel, it must be converted back into a gas.
Sumitomo Precision developed heat exchanger technology and was the first manufacturer in Japan to develop LNG vaporizers. Today, as a leading global manufacturer, we supply LNG vaporizers to LNG receiving terminals not only in Japan but around the world.
