Cryogenic Systems and Transfer Lines |
"Cryo" comes from the Greek word "Kryos" and means ice cold. Cryogenics is technique at very low temperatures
Physical properties of gases at temperatures lower than minus 160°C can be used for quite different applications. Transfer lines play a decisive role for the distribution of refrigerants.
History:
- 1853 Joule finds the cooling effect of expanding gas
- 1889 Dewar liquefies H2
- 1895 Von Linde liquefies air
- 1908 Kamerlingh-Onnes liquefies Helium at -269 °C.
- 1916 Production of liquid Argon at -186 °C
- 1922 Production of liquid Neon at -246 °C
- 1948 Cryogenics starts its commercial story of success
