Ryuku University was founded in 1950 and is one of the few universities in Japan which owns and operates its own high purity liquid nitrogen plant.

The university uses liquid helium and nitrogen for research into super conductive magnetism and nuclear magnet resonance of high temperature super-conductors.

The new plant will supply the university’s low temperature research centre with high purity liquid nitrogen.

The investment decision was taken due to the high price of liquid nitrogen in the region and the university’s need for an uninterruptible source.

Linde CryoPlants was able to satisfy their needs with their LINIT 25, which in this case was producing 20 litres per hour at purity of 99.5%.

Linde CryoPlants has considerable experience in the supply of cryogenic nitrogen plants to research institutes worldwide and is ideally suited to this new facility.
