Electric Heating Freeze Dryer LGJ-FD Series

Electric Heating Freeze Dryer LGJ-FD Series

LGJ-FD series Freeze Dryers are with electric heating function.

Equipped with shelf heating and has programmable functions.

It can memorize freeze-dried curves and comes with u-disc extraction function for users to observe the lyophilization process of materials.

    1. It is our company's patented product . Freezing and drying is finished in the same place. It is easy to operate,and have a good drying effect.
    2. The ACRYLIC material is used for the drying chamber door. It is colorless, transparent, and the whole process of lyophilization can be observed.
    3. Inflatable (drainage) valves use safety diaphragm valves, which can be connected to an inert gas source,  and  filled with inert gas after drying to extend material storage time.
    4. Patented gas diversion technology, uniform ice catching in cold traps, and strong ice catching capability.
    5. Internationally renowned brand compressors, high efficiency, long life, low noise.
    6. Separator patented technology and partition temperature fuzzy control technology, the shelf temperature difference is small, the temperature control accuracy is high, and the drying effect is even.
    7. The freeze-drying curve optimization control technology can control the cooling rate in the pre-freeze phase, and at the same time, it can control the sample heating rate and the current stage vacuum degree in the sublimation and analytical drying stages.
    8. The powerful sensor calibration function ensures the long term accuracy  of the measured value.
    9. 7-inch true color industrial embedded touch screen + SH-HPSC-II modular controller, high control accuracy, stable and reliable performance.
    10. The professionally designed FD-EMB control system can save hundreds of process recipes. Each recipe contains 50 temperature control zones to improve the process optimization rate.
    11. Intelligent data recording system, real-time record and display the cold trap temperature curve, sample temperature curve, vacuum curve, export data can be viewed through the computer and print a variety of operations to facilitate process optimization and verification of drying effect.
    12. Flexible manual + automatic control, manually used for groping the process, automatically used for mass production.
    13. Real-time alarm display and historical alarm query function to facilitate fault diagnosis and equipment maintenance.
    14. You can set the user level and password, and decentralized operation management.
