How does the elan2 create liquid nitrogen?

Air is pulled into an external air compressor and compressed to100 PSI, and the water vapor is removed. The slightly pressurized air is then fed into the main elan2 Liquid Nitrogen Generator System. Other contaminants are removed through a series of filters and membranes leaving just nitrogen gas. The oxygen and other gases are returned to the room.

The nitrogen is then liquefied through a two step process - a special Kleemenko cycle based refrigeration system is used to cool down the air to a specific temperature. Once at this temperature, the cool and pressurized nitrogen gas is reduced in pressure, resulting in liquefaction through a process called the Joule Thomson Effect. The liquid nitrogen is transferred to the internal storage container, ready to deliver on-demand when needed.
