60L/day He Liquefier
Helium Recovery System – A series of tubes that can be connected to Helium refrigerators to recover any leaked helium gas. These tubes feed into a refrigerator and compressor system that stores the helium for later use.
RAC2 uses a building-wide Helium recovery system. This system recovers and recycles ~90% of all helium used in cryogenic experiments. Any experiments using Helium gas are hooked onto a recovery tube in the local lab. Helium gas recovered through this tube is collected and super-cooled again, before being stored for use in future experiments. We use this He recovery system to guarantee regular, reliable supplies of Helium for experiments.
Our Helium recovery system is the largest of its type on campus. It has been in operation since 2016, and as of summer 2018, has recovered over 17,000 Litres of Helium. With this recovery system, we are guaranteeing regular supplies of valuable Helium for our researchers.
