Audited Supplier DW-20F Silicone Oil Heating Freeze-Drying Machine
1. Pre-freeze drying process at in situ situation, reduce the complicate operation from drying process, become automatically;
2. Shelf temperature differences ± 1 ºC, dry effect uniform;
3. Intermediate medium circulation technique, shelf can refrigeration, heating, temperature adjustable, controllable, pilot scale test and production process;
4. Due to drying chamber and cold trap for fission structure, special gas circuit designed, capture water ability is strong and drying time to be short;
5. Embedded touch screen, PLC controlled and PID temperature controlled display lyophilized curve and history curve;
6. Control system can be stored 40 freeze-dry process programs, each program can have 40 temperature settings, and can choose the manual operation and automatic operation, the Top-Press type is equipped with an automatic defrost function;
7. Optional eutectic point test device;
8. U disk data available;
9. Equipped with PC software can print curve, browsing curve, modify data;
10.Square tray is shape not easily to deformed, easy to operate and clean;
11. Can be configured charging valve, rechargeable dry inert gas.
12. Drying chamber adopts high light colorless transparent organic glass door, in operation process can be observed clearly the change of material process;
13. Refrigeration system using overlap refrigeration technology, low refrigeration temperature, large refrigerating capacity, and adopt imported closed compressor, high efficient and reliable, low noise.
