Freeze drying plants for file rescue and archaeology

These special freeze dryers are designed for file rescue and drying of archaeological finds and other restoration tasks (wooden finds preserved in PEG such as parts of ships, dugouts, boat finds, etc.). With the help of two ice condensers a continuous operation with a duration of up to 12 months can be realized.
We can offer different chamber dimensions up to a nominal diameter of 2m and a length of 10m.
