Small liquid nitrogen machine: Compact LN2 Production Guide
Jun 16 , 2026The demand for adaptable cryogenic solutions has been increasing across various industries. Because of this trend, the small liquid nitrogen machine is becoming more popular.
More specifically, this machine provides the capability for on-site nitrogen liquefaction. Users are then less reliant on the delivery of liquid nitrogen.
More so, compact systems tend to add flexibility to operations and decrease the cost of gas supply over time.
Small liquid nitrogen machines produce liquid nitrogen from the air.
Also, small systems integrate the separation and liquefaction of air.

Usually, these types of systems are designed for laboratories, small-scale factories, and research institutes.
Furthermore, systems of this size allow for a stable supply of LN2 without the need for external gas cylinders.
The small liquid nitrogen machine separates air and utilizes cryogenic cooling.
To begin, the machine compresses the air.
Then moisture and contaminates are removed.
Next, the air is cooled to cryogenic temperatures.
After this, the cooled air is separated into its gaseous fractions.
Lastly, the nitrogen is then completely liquefied.

For these reasons, the machine is capable of continuous liquefaction of nitrogen.
The small liquid nitrogen machine has multiple distinct parts.
1. Air Compressor
This first part is used to provide the system with compressed air.
2. Air Purification Unit
This second part is used to remove moisture, oil, and CO2.
3. Heat Exchanger
This third part is used to cool air to the desired temperature.
4. Expansion Unit
This fourth part provides the system with the necessary refrigeration.
5. Distillation Column
Finally, this part of the system separates nitrogen from air.
