Features
7-inch color LCD touch screen, the important parameters (cold trap temperature, sample temperature, vacuum degree, partition temperature) are intuitively visible;
Manual and automatic operation can be switched at will, and one machine has multiple functions;
Industrial-grade PLU controller, stable and reliable, with strong anti-interference;
The compressor and vacuum pump circuit independently control the protection program to prevent the compressor from being frequently started and stopped due to misoperation;
The freeze -drying data is automatically saved, viewed in real time, the history is reproduced, and the freeze -drying process is clear and controllable;
The freeze-drying formula can be stored, and each group can be edited in 36 segments, which can be called at any time, and can be customized and renamed to achieve direct identification and distinction;
Multi-layer permission settings, convenient for device management, with screen security lock to avoid misoperation;
With function of automatically protecting freeze -dried data after power failure , and can support U disk data export and viewing;
There is an observation window inside, and the drying room adopts an aviation acrylic transparent door , which can clearly observe the changing process of the material during the freeze-drying process;
The temperature of the partition is adjustable and controllable, and the pilot test and production process can be explored. Because the drying chamber and the cold trap are separated structures, the water trapping ability is strong and the drying time is short;
Equipped with an inflatable valve, which can be filled with dry inert gas;
Standard high-precision micro-control valve, which can realize manual vacuum adjustment, optional automatic vacuum adjustment valve, automatic control of vacuum;
