Working Principle
After absorbing heat from the cooled substance in the evaporator, the liquid refrigerant vaporizes into low-pressure and low-temperature vapor. It is sucked into the compressor and compressed into high-temperature and high-pressure vapor before being discharged into the condenser. In the condenser, heat is released to the cooling medium (water or air), and the refrigerant condenses into high-pressure liquid. It passes through the throttling device and becomes low-pressure and low-temperature liquid, then re-enters the evaporator to absorb heat and vaporize again.

Product Features
● Manufactured based on vacuum freeze-drying principle. It has compact and reasonable structure, convenient maintenance and low cost. Equipped with fully automatic control for simple operation.
● Complete functions with no auxiliary facilities required (such as steam boilers, cooling towers). It can operate independently once connected to three-phase power supply.
● Unique design with low energy consumption, making freeze-drying of various materials economically viable.
