Liquid Nitrogen Generators are suitable for production of liquid nitrogen from 10 liters to 240 liters per day.
The liquid nitrogen plants come with their own dewars offering storage from 35 liters to 500 liters.
Our systems are designed to run 24 hours a day, 7 days a week with no major maintenance required for several years.

HOW IT WORKS
Production of Liquid nitrogen takes place in two distinct steps. First, nitrogen gas is produced from air. Second, the gaseous nitrogen is passed through a cryorefrigerator to liquefy the gas to produce liquid nitrogen.
Nitrogen is made from air using separation technology for separating Nitrogen from other constituents of air. This nitrogen gas is then passed through a cryorefrigerator.
The cryorefrigerator consists of a cold head, Helium compressor package and a pair of stainless steel flexible helium lines. The cold head is mounted into the top of the liquid tank (dewar). The cold head extends down into the neck of the liquid tank for the purpose of cooling the nitrogen entering the liquid tank to 77K (-196°C). The nitrogen gas liquefies on contact with the cold head heat exchanger. The liquefied nitrogen drips off the heat exchanger down into the liquid nitrogen inside the dewar. The flow rate of the nitrogen gas into the dewar is controlled by the rate of liquefaction inside the liquid tank. Therefore, if the cryorefrigerator is turned off by the level indicator, the liquefication stops and the flow of nitrogen into the tank stops.

Our Liquid Nitrogen Gas Generators are widely used across many applications including:
- Freezing and transport of food products
- Cryopreservation of biological samples such as bull semen
- Cryotherapy to remove skin abnormalities
- Shielding materials from oxygen exposure
- Coolant for superconductors, vacuum pumps, and other materials and equipment
- Cooling material for easier machining or fracturing
