Process control

Freeze drying process:

Loading – Primary freezing – 1st drying process – 2nd drying sublimation process

Manual control:

Input conditions and parameters for the process from freeze to 1st / 2nd drying processes. Process is finished after checking completion of drying.

Automatic Control:

Select protocol. Parameters of Pre Freeze ~ 1st/2nd drying processes are automatically set up. Process is completed by P-rise test system inside of chamber after whole process is finished.


Sample temperature 1,2,3 /shelf temperature/condenser temperature/vacuum level.

Drying chamber:

Cooling speed:

From 20ºC to -40ºC (1ºCmin) in less than 60 minutes.

Shelf Temperature Uniformity:

Less than +/- 1.5ºC

Vessel Pressure Standard:

Qualified chamber under vacuum gauge pressure lower than 5×10³ Torr


Cold Trap Chamber, Condenser

Cooling speed:

From 20ºC to -70ºC in less than 30 minutes.

Defrosting system:

Hot gas solenoid method. Fast defrosting by steam and hot water. Removes ice in less than 30 minutes.

Vacuum System

Pull Down Time:

From 760Torr to 100mTorr in less than 45 minutes. Lower than 20mTorr eventually.
  • All in one function, operates in minimal space
  • Pilot scale condenser capacity: 10~30 liters/batch
  • 0.6 ~ 2.0 m² various shelf area and distance (standard: 60mm)
  • Selectable shelf application (Bulk or Vial stoppering)
  • Shelf temperature range (-45ºC to 80ºC)
  • Selectable condenser temperature (-80ºC/ -120ºC)







Selection between Auto and manual mode. Alarms, Lamp, temperatures set up are displayed. Entire process time, shelf temperature, cold trap temperature, vacuum level are monitored. The whole process is visually monitored.
