Liquid N2 Generator


Our innovative Liquid N2 Generator revolutionizes the way businesses access and utilize liquid nitrogen (LN2) by enabling on-site production. This cutting-edge solution eliminates the need to purchase LN2 from external sources, providing a more convenient, cost-effective, and safer alternative.
With our Liquid N2 Generator, you can avoid the hassles associated with transporting, storing, and handling liquid nitrogen. Once the machine is connected to a power source and cooling water, the process begins with the generation of gaseous nitrogen using a PSA or membrane nitrogen generator, ensuring an oxygen content of no more than 1.0%.
In the second stage, the nitrogen gas undergoes a remarkable transformation. Using a helium compressor and a cold-head, the gas is rapidly cooled to -196°C, causing it to condense into liquid nitrogen. This process takes around 4 hours, yielding high-quality LN2 ready for use.
By embracing our Liquid N2 Generator, businesses across various industries can streamline operations, reduce costs, and enhance safety. Experience the convenience, control, and peace of mind that comes with generating your own liquid nitrogen on-site.

Product Details

For companies looking to improve the efficiency of their liquid nitrogen (LN2) supply chain, our state-of-the-art Liquid N2 Generator provides a revolutionary solution. By enabling on-site production, clients can avoid the inconveniences of transportation, evaporation losses, and any safety hazards connected with handling liquid nitrogen by not having to buy LN2 from outside suppliers.
Getting started with our Liquid N2 Generator is a simple process. Once the machine is properly connected to a power source and cooling water, it begins by generating gaseous nitrogen using a PSA (Pressure Swing Adsorption) nitrogen generator. This initial stage ensures that the nitrogen gas has an oxygen content of no more than 1.0%, a process that takes approximately 30 minutes. For even faster output, a small membrane nitrogen generator can be utilized as an alternative.
The real magic happens in the second stage, where the nitrogen gas undergoes a remarkable transformation. Utilizing a powerful combination of a helium compressor and a cold head, the gas is rapidly cooled to an astonishing temperature of -196°C. This intense cooling process, which takes around 4 hours, causes the nitrogen to condense and transition into its liquid state, yielding high-quality liquid nitrogen ready for immediate use.
Our Liquid N2 Generator continues to produce liquid nitrogen at the specified flow rate per day until the storage vessel reaches its full capacity. Once the storage is filled, the plant intelligently enters a standby mode, conserving energy and resources. However, as soon as the storage volume drops to a pre-set level, the generator automatically restarts, ensuring an uninterrupted supply of liquid nitrogen.
To provide users with complete control and peace of mind, our Liquid N2 Generator features an advanced control unit that displays all the essential information, including flow process data, alarms, trend curves, and more. This comprehensive monitoring system ensures continuous nitrogen supply, allowing businesses to focus on their core operations with confidence.
By embracing our Liquid N2 Generator, businesses across various industries can revolutionize their liquid nitrogen management, reducing costs, enhancing safety, and gaining unprecedented control over their LN2 supply chain. Experience the convenience and reliability of on-site liquid nitrogen generation and unlock new possibilities for your business with our innovative solution.
