This two-stage ultra-low temperature refrigeration system uses NH₃ (ammonia) as the primary refrigerant, delivering reliable cooling performance even below –40°C by leveraging the superior thermal properties of natural refrigerants.

With high thermal efficiency, NH₃ provides powerful cooling capacity while reducing compressor load, ensuring dependable operation in demanding low-temperature processes. Its near-zero GWP also enables long-term operation without concern for F-gas regulations.

The system further enhances environmental performance by using low-GWP R32 as the secondary refrigerant, achieving strong heat exchange efficiency while minimizing environmental impact.

● High Efficiency
