Calorex helps protect historical records

rreplaceable historical documents, some dating back to Norman times, and which have survived more by luck than by judgment, are now being preserved with the help of two Calorex OTW15 dehumidifiers. The collection of parchments, records, maps and photographs are cared for by the archives department of Shropshire Council at its Shrewsbury headquarters. Environmental engineers Cool Services specified two wall-mounted dehumidifiers as a reliable and efficient method of preventing excessive humidity.

The archive receives 10 000 visits a year from the public, with hundreds of thousands more researching catalogued information via the Internet.
