Freezing/vacuum-drying systems for low-volume production and research by the pharmaceutical industry require space-saving designs, low cost and high functionality. ULVAC has released the DFM Series to meet these demands.


  • Touch-panel operation, operation display, warning display, maintenance display
  • Shelf temperatures can be controlled by programs.
  • Completely automatic operation
  • Electronic expansion valve is provided standard.
  • Shelf plates are temperature-controlled by circulating a heating medium.
  • Standard lineup includes models supporting C/SIP.


  • Low-volume freeze-drying processes for
    pharmaceutical products
