A small liquid nitrogen machine is an apparatus that converts nitrogen gas into its liquid state by compressing and cooling it. The compressed gas is first passed through a heat exchanger to remove excess heat and reduce its temperature before being fed into a liquefier. In the liquefier, the gas is cooled to a temperature below its boiling point to convert it into a liquid that can be stored and used for various applications.
