1. Fully automatic program freezing: Once started, the entire freezing process is completed automatically without human intervention.
2. Imported touch screen control panel.
3. Built-in imported PLC control system, no need to connect to an additional computer. It continuously and automatically converts and calculates the cooling temperature to control the amount of liquid nitrogen entering the freezing chamber. The system generates a conversion result every 7 seconds, and it sends the latest instructions, ensuring temperature accuracy and minimizing temperature errors.
4. Imported temperature probe with high sensitivity and real-time temperature display.
5. 360-degree air outlet design in the freezing chamber ensures consistent temperature at all locations in the freezing chamber, ensuring consistent freezing results for specimens frozen in different areas.
6. Turbine fan in the freezing chamber ensures rapid and uniform freezing of the freezing chamber temperature without error.
7. Quick program setting with no quantity limit, meeting the freezing requirements of different animal and species semen.
8. No self-pressurized liquid nitrogen tank is required, making it more convenient and simple to use; simply pour the liquid nitrogen into the foam box at the back.
9. A pressure-free liquid nitrogen cooling system eliminates the need for pressurized liquid nitrogen tanks to meet program freezing chamber cooling requirements, ensuring safety and eliminating potential safety hazards.
10. Temperature range: 40°C to -160°C
11. A complete freezing cycle takes 7 minutes, and program times can be customized.
12. The freezing cycle can be easily configured: temperature, time, and cooling rate can all be quickly set.
13. Simple control: Control the touchscreen to start and stop the freezing cycle, making it easy for both experienced and inexperienced users to operate.
14. Real-time curve recording: Each freezing process temperature is recorded in a historical curve for easy review and evaluation.
15. Alarm notification upon completion of freezing.
16. The set temperature is maintained even when no one is operating the freezing cycle, ensuring safety and preventing damage to frozen specimens. 
17. Low liquid nitrogen loss: Very little liquid nitrogen is needed per freeze, reducing operating costs.
18. Power: 160W, low energy consumption.
