KOCH 1610 Helium Liquifier

The current Helium Liquefier in operation is of KOCH make; Model 1610s was installed and commissioned during January, 1992. The liquefier is liquefying since then without any major trouble. The above is capable of liquefying helium, which varies from 15 liters per hour to 75 liters per hour under various operating condition mentioned below.
Without LN2 pre-cooling:
  1. 17 to 45 liters per hour with pure gas
  2. 15 to 25 liters per hour with impure gas
With LN2 pre-cooling:
  1. 25 to 70 liters per hour with pure gas
  2. 45 to 55 liters per hour with impure gas
New Helium Liquifier Installed in TIFR :
To meet the growing liquid helium demand, LTF-TIFR recently installed the fully automated, PLC controlled modern helium liquefier. Model: L-280 Linde make. The above plant was installed by LTF-TIFR and ready for commissioing
