Deacidification system for books.

The Bookkeeper® Deacidification Process neutralizes harmful acids and greatly extends the lifespan of books and documents.

Accelerating aging tests have demonstrated that paper treated with Bookkeeper will have a life expectancy of a minimum of three to five times longer than that which has not been treated. Demaco produces for the company Preservation Technologies their Bookkeeper® Deacidification system which contains a Recovery skid, a Mix Skid and several vertical and horizontal treating vessels as well as vacuum vessels with pumps and valves.
