Using this technique the deep frozen files, books, plans etc. are dried by sublimation (direct transformation from ice to vapour).
Our dynamic vacuum freeze drying provides the highest possible level of drying quality for all kinds of paper, leather, parchment, paper-based art and cultural heritage as well as for other sensitive materials provided the recovery and freezing has been carried out by experts in this field, i. e. using the docusave-system. Through using our drying method no further damage is caused.
Information stating which material we are dealing with (e.g. contents of wet archive boxes) is essential for our work. Without this information we cannot adjust the settings of our systems accordingly.
