DW-18ND Vertical Freeze Dryer With Heating Function System

The ND freeze dryer adds heating to the N-series, accelerating the drying process, saving energy, and providing heating curve settings with a variety of drying solutions for laboratory use.


  • Ordinary type: Suitable for bulk materials, liquids, and solids drying.
  • Top-Press type: Suitable for the drying of Schering bottled material, the vacuum bag can be sealed and sealed by the sample, including the common type of using function.
  • Ordinary multi-manifold type: Suitable for bulk materials or small materials of freeze-dried, while the external freeze-dried bottles, eggplant-shaped bottles, jars.
  • Top-Press multi-manifold type: Contains the use of ordinary multi-manifold features, enabling the vacuum bagging of the sample envelope, to meet most of the laboratory technical requirements.

Features of DW-18ND Vertical Freeze Dryer

  1. The machine uses the international brand Danfoss compressor refrigeration, refrigeration quickly, cold trap temperature is low.
  2. 7-inch true color touch LCD screen control system, easy to operate, and powerful.
  3. Industrial embedded operating system, ARM9 core control circuit design, 32M memory 128M FLASH, the operation response speed, and a large amount of stored data.
  4. The control system automatically saves the freeze-dried data and can be a real-time curve and historical curve in the form of view, the entire freeze-drying process clear.
  5. In the drying room with a colorless transparent polycarbonate drying room, the sample is clear and intuitive and can observe the whole process of freeze-drying.
  6. Vacuum pump and host connection using the international standard KF quick connector, simple and reliable.
  7. The machine can store multiple freeze-drying curves, and use a U disk to extract data to the computer, with the host computer software in the computer to browse print and a variety of options.
  8. With the company’s unique point heating curve calculation method, the temperature is more stable, no overshoot, and temperature control more accurate.
  9. Equipped with an inflatable valve, can be filled with dry inert gas.
  10. Partition temperature adjustable, controllable, can be explored, pilot and production process.
  11. With manual and automatic two modes of operation, you can manually explore the new material freeze-dried curve.
