Working principle:
Liquid Nitrogen plant :
The Stirling Liquid Nitrogen plant (StirLIN-4) is used to produce liquid nitrogen. The nitrogen is separated from compressed ambient air (consisting of 78 % nitrogen) using adsorption desorption process. Subsequently, the nitrogen is condensed and stored as liquid in storage container under positive pressure.
Main parts of helium plant
- Air compressor
- Air vessel
- Dryer
- Pressure Swing Adsorption system
- Nitrogen Vessel
- Cryogenerator
- Dewar
Liquid Helium Plant :
Liquefier (Cold Box)
The process gas (Helium) compressed and isentropic expansion in an open cycle via Turbo-Expanders until the Helium temperature falls below inversion temperature. Then isenthalpic expansion in Joule-Thomson device and helium gas is liquefied, stored in dewar at slightly above atmospheric pressure.
Main parts of helium plant
- Recirculation compressor
- Oil removal System
- Buffer Vessel
- Cold Box
- Dewar
- Recovery gas bag
- Recovery compressor

Instructions for Registration, Sample Preparation, User Instructions, Precautionary Measures and Charges
--
Instruction for users :
The users are requested to apply in IRCC central facility registration (https://drona.ircc.iitb.ac.in/NewFac/CentralFacilityIndex.jsp?facilityCode=ME007) either before coming to collect the liquid nitrogen or at the time of collection. Faculties, Students, Project staff can apply in this portal. As of now Institute staff are not allowed. For the students who are not able to apply, can ask their friends to lab mates to apply and choose the faculty of the students who required LN2. In the meantime they can mail software@ircc.iitb.ac.in their issue & get it rectified.
Caution:
Users are instructed to bring their own containers and with some liquid helium in the container.
Applications
Liquid Nitrogen Plant : The LN2 most commonly used for cryopreservation of cells and microbes. Also used in Liquid Helium plant for precooling, in NMR for prevent heat leak into LHe, High temperature superconductors etc.
Liquid Helium Plant : The liquid helium produced can be used for cooling purposes down to 2 K for doing various experiments at low temperatures. Liquid helium can also be used for cooling superconducting magnets such as the ones used in NMR machines, MRI machines, etc.
