Castle defence
Munters has installed dehumidifiers in archive rooms at Belvoir Castle, Rutland, to protect the family’s historical records from deterioration and moisture damage.
Belvoir Castle has been the ancestral home of the Duke of Rutland’s family since 1067.
To ensure the preservation of its precious archives for future generations, Belvoir Castle chose Munters to install state-of-the-art dehumidifiers in the castle’s archive rooms. These rooms house a vast collection of books, documents, maps, manuscripts and estate management records, with the oldest document dating back to 1103. However, the passage of time has taken its toll on many of these documents, and humidity and moisture has caused visible damage such as mould growth, yellowing and discolouration.
Recognising the need to protect these irreplaceable records, Munters was selected to design a dehumidification solution tailored to the unique challenges of Belvoir Castle. Each of the five dehumidifiers installed were selected to maintain consistent relative humidity levels of 50-55% RH, preventing further damage and ensuring the long-term preservation. This solution meets the British Standard BS4971 for conservation in archives, as well as reducing the need for additional heating, which in turn saves energy.
