🚀 Key Features
🤖 Autonomous Operation

Designed for independent operation, eliminating the need for constant supervision.

📏 Compact Design

Minimal land footprint with a maximum height ≤ 2500mm, fitting comfortably in diverse spaces.

Rapid Output

Delivers liquid nitrogen results in just 1.5 hours after start-up.

🛠️ Easy Maintenance

Utilizes standard refrigerator compressors for safe, reliable, and maintenance-friendly performance.

🔄 Zero Downtime

Features zero downtime maintenance with no defrosting needed for continuous operation.

⚙️ Working Principle

This nitrogen liquefier is powered by a sophisticated cryogenic mixed refrigerant throttle refrigeration system. It incorporates a regenerative multi-component mixed refrigerant throttle cycle. By selecting components with varying boiling points—high, middle, and low—each aligns effectively with its respective refrigeration temperature zone, facilitating cooling from ambient temperature down to a frigid -196 °C, achieving efficient nitrogen liquefaction (-180 °C @ 0.6 MPa).
