USC Liquid Helium Recovery System
We considered an LHeRS back in 2010
Not considered cost effective at that time
We then added to EPR with cryoprobes in 2012
Now it was considered practical
Considered several systems with a capacity of about 20L LHe/day capacity
Quantum Technologies had such a system at the best price of $213,000
Installation, Cu piping and labor: >$100,000
