Vacuum Insulated Piping [Manufactured by Jeck Tohri] ◎Certified by the Minister of Economy, Trade and Industry
There are many examples of use in supply piping for various liquefied gases such as liquefied nitrogen, liquefied oxygen, and liquefied hydrogen. The evaporation loss is very low, and it is maintenance-free after installation.
The vacuum insulated piping manufactured by Jeck Tohri is used for the supply piping of various liquefied gases such as "liquid nitrogen," "liquid oxygen," and "liquid hydrogen." It has very low evaporation loss and is particularly adopted for various applications such as cooling in MBE, preventing oxidation in soft drinks, and boosting pressure. Additionally, one of its strengths is that it is maintenance-free after installation.
