Polygon’s National Documents Center in Allentown, Pennsylvania is home to one of the most important tools in our document recovery process, the freeze-dry chamber. For 15 years, this machine has been running nonstop, turning frozen water directly into vapor and logging over 100,000 hours of operation.
While the chamber is vital in restoring water-damaged documents, it also comes with an environmental tradeoff. In 2023, the Documents Center used nearly 266,000 kWh of electricity, with the chamber driving much of that demand.
