Archive Centre Blekinge
In 2015 Archive Centre Blekinge inaugurated their new facilities containing more than 10 km shelf meters in a 2-story building on the outskirts of Bräkne-Hoby in southern Sweden.
After 30 years in an old building, Blekinge Archive was running out of space and the need of a new building created a chance for the 3 archives to join forces.
Today the facility forms a research centre for cultural heritage, family history and local history where a public research room and modern meeting facilities are made available free of charge to all interested individuals and groups.
The oldest document in the archive dates back to 1643, and documents as well as a large number of private and public collections of everyday articles from the county makes up an irreplaceable testimony of the past. An important part of the local history that has to be stored safely for the future.
High demands on climate control
The new archive building strives to fulfill the Swedish "Healthy-house concept", and among other environmentally friendly initiatives, the electricity consumption is covered fully by a solar cell system on the roof. In case of excess production, the primary school in the neighboring building purchases the electricity.
The archive follows the guidelines from the Swedish National Archives as to indoor climate conditions, lined out to a temperature of 18 ° C (± 2 ° C) and a relative humidity of 30-40% RH (± 5% RH) year round. At these climate conditions the stored items will be properly protected from moisture related damage and can be preserved for future research.
ML Plus - combined solution for temperature- and humidity control
Munters and the construction company Skanska has specifed a Munters ML23 Plus climate system, specially configured to the new archive’s needs.
The system is based on a Munters ML desiccant dehumidifier with a nominal airflow of 2300 m³/h.
By adding standardised modules for humidification, cooling and heating, the ML Plus system provides a perfectly stable indoor climate, 18°C/35%RH around the year - completely independently of the outdoor fluctuating temperature and moisture conditions.
The system was delivered in modules that were assembled on site. The compact design secures a neat looking system with a very small footprint compared to a traditional solution with separate devices from different vendors.
In the old archive premises there was no climate control and the stored objects were subject to large and problematic fluctuations in relative humidity, typically between 30-70% RH. In summer small dehumidifiers were temporarily installed in an attempt to reduce the high humidity, which over time can be totally devastating for the old documents.
Head of Blekinge Archives, Per Lundin, expresses great satisfaction with Munters’ climate control solution and in particular he highly appreciates the stability and reliability. The plant is monitored seamlessly via the archives common BMS system and with a Service Agreement with Munters that will ensure regular and optimal maintenance, the archive staff do not need to worry about any physical inspection, filter change etc.
