NEL-50FD In-situ freeze dryer with electric heating

NEL-50FD (electric heating) freeze dryer, in situ freeze drying. It changes the tedious operation of the drying process in the past, prevents the contamination of materials, and realizes the automation of drying and sublimation. 

This model has shelf heating and programmable functions, and can memorize the freeze-drying curve, which is convenient for users to observe the freeze-drying process of materials.


1. Pre-freezing and drying are completed in situ, which is easy to operate.

2. The door of the drying chamber is made of ACRYLIC material, which is colorless and transparent, and the whole process of freeze-drying can be observed.

3. Can be connected to inert gas source,

4. The cold trap can capture ice evenly and has strong ice capture ability.

5. International famous brand compressor, low noise.

6. The shelf temperature difference is small, the temperature control precision is high, and the drying effect is uniform.

7. The freeze-drying curve optimization control technology can control the cooling rate in the pre-freezing stage, and at the same time control the sample heating rate and the vacuum degree value in the current stage in the sublimation and analytical drying stages.

8. Powerful sensor calibration function to ensure the accuracy of measured values for long-term use.

9. 7-inch true color industrial embedded touch screen + SH-HPSC-II modular controller,

10. Professionally designed FD-EMB control system

11. Intelligent data recording system,

12. Flexible manual + automatic control mode,

13. Real-time alarm display and historical alarm query function,

14. The user level and password can be set, and the operation management can be carried out in a decentralized manner.
