oxygen-poor storage chamberpest control
Effective pest control on arts and cultural goods
With free capacities, the Landesmuseum Hannover offers other institutions and individuals the opportunity to effectively combat pests in art and cultural objects without the use of pollutants.
the technical procedure
The infested objects are stored for four to five weeks in a hermetically sealed room. The oxygen content is reduced to less than one percent, which completely kills animal pests and larvae and eggs. Over time, the amount of nitrogen in the room increases to about 99,5 percent. Meanwhile, the nitrogen behaves inertially, which means that no chemical reactions take place during the treatment of the objects.
The Landesmuseum Hannover owns two of these so-called oxygen-poor storage chambers with a respective capacity of 45 cubic meters. This fully automatic, computer-controlled system is one of the most modern in Germany. The method takes into account temperature and relative humidity. All desired parameters are automatically kept constant during the treatment.
