Co-development with Gyu-Baek An’s team from Chosun University
Compression and tensile test of metal material in minus 253 degrees Celsius
Replacing imports such as expensive liquefied helium and extr
CRYO H&I has developed an equipment capable of testing metal materials in extreme low temperature environment of minus 253 degrees Celsius. Localization of extreme low temperature test equipment is expected to speed up the development of liquid hydrogen storage technology. CRYO H&I is a company that manufactures extreme low temperature vacuum pumps for semiconductors·displays.
CRYO H&I developed a device that evaluates the compression·tensile properties of metal materials in an environment of minus 253 degrees Celsius. It was jointly developed with Gyu-baek An, a professor at Chosun University’s Department of Smart Vehicle System Engineering.
The extreme low temperature test equipment is expected to be used in the development of liquid hydrogen storage·transport container materials. Considered a clean energy source, hydrogen, becomes liquid hydrogen when cooled to minus 252.7 degrees Celsius. Liquid hydrogen has only 1/800 of its volume compared to its gaseous state. The cost can be greatly reduced by storing and transporting it in the state of liquid hydrogen.
In order to tolerate an environment below minus 253 degrees Celsius, the storage container must have high durability. Development of liquid hydrogen storage tanks is led by large corporations. In order to research materials suitable for extreme low temperatures, liquid helium or extreme low temperature refrigerators had to be imported at high prices.
An official from CRYO H&I explained, “We will not only contribute to the development of extreme low temperature materials but also the localization of testing equipment.”
CRYO H&I possesses extreme low temperature refrigeration technology that can reach below minus 265 degrees Celsius. The compressor and cylinder repeatedly compress·expand the helium gas to create extreme low temperature environment.
CRYO H&I is expecting that extreme low temperature refrigeration technology will be applied to future key industries such as aerospace, medical care, and quantum computing. Liquefied fuel, cold chain, and cooling equipment, each requires extreme low temperature technology.
CRYO H&I is currently producing extreme low temperature vacuum pumps that combine extreme low temperature technology with a vacuum pump. After removing the kinetic energy by cooling the gas molecules, a pump removes the molecules to create a vacuum state. Extreme low temperature vacuum pumps are mainly used in semiconductor and display deposition processes.
CRYO H&I is concentrating on the development of extreme low temperature technology application products based on the acquisition of test device technology that they just launched. Last year, the plant was moved to Pyeongtaek and the company is strengthening their R&D capabilities.
Won-kyun Yang, head of CRYO H&I research center, said, "We will develop refrigeration technology that can be applied to various fields and become as the best extreme temperature refrigerator company in South Korea."
