Polygon now has the most sophisticated document restoration technology of its kind in the U.S. in the form of a vacuum freeze dryer. The new vacuum freeze dryer has a capacity of up to 2,000-cubic-feet per month, a controlled drying and monitoring system to prevent over-drying and the ability to restore water damaged books and documents without any distortion or warping.
In a press release, director of Polygon’s field services Joe Perko stated:
“Our vacuum freeze dry chamber is not to be confused with the glut of thermal vacuum dryers in the market, which can cause warping of paper and other material. We truly achieve the triple point of sublimation and safeguard the longevity of our clients’ books and valuable papers.”
When books and documents fall victim to water damage, the recovery process involves blast freezing the items to preserve them. The new technology in the vacuum freeze dryer does not allow the ice in that paper to melt. Instead, the ice turns into a gas via the manipulation of pressure and temperatures within the chamber. This system is great for libraries, government offices, businesses, archivists and conservators who seek to preserve wet documents and rare books in order to prevent further damage and mold growth.
