Industrial use

In industrial production, liquid nitrogen obtained by compressed liquid air fractionation can be used as deep refrigerant. Because of its chemical inertia, it can directly contact with biological tissue and freeze immediately without destroying biological activity, so it can be used as deep refrigerant

Working principle

Advantages of Liquid Nitrogen Generators (LN2 Generators)

1. Ultra-Fast Cooling & Precision Temperature Control

   • Delivers rapid cooling to -196°C (-320°F), ideal for cryogenic applications in food freezing, medical preservation, and material testing, ensuring product integrity and minimal thermal damage.

2. Energy Efficiency & Cost Savings

   • On-site nitrogen generation eliminates reliance on third-party suppliers, reducing transportation costs and storage risks. Automated systems optimize gas usage, cutting operational expenses by up to 30-50%.

3. High Purity & Consistency

   • Produces 99.999% pure liquid nitrogen, free from contaminants, critical for sensitive industries like pharmaceuticals, electronics, and aerospace.

4. Enhanced Safety & Sustainability

   • Non-flammable and inert properties minimize explosion risks. Eco-friendly operation reduces carbon footprint compared to traditional refrigeration methods.

5. Versatility & Scalability

   • Adaptable to diverse applications: cryogenic grinding, shrink-fitting, IVF storage, and more. Modular designs support customization for small labs to large industrial plants.

6. Low Maintenance & Reliability

   • Robust construction with advanced monitoring systems ensures 24/7 operation. Minimal downtime due to automated alerts for maintenance needs.

7. Compliance & Certification

   • Meets international standards (ISO, CE, FDA) for food safety, medical use, and industrial safety, ensuring global market acceptance.
