In addition to anoxia, sometimes people can rent walk in freezers. Humidity can be an issue with some of them, but if you can wrap your materials it should be ok.</div>

I also encourage you to reach out to the MuseumPests.net PestList as there are many professionals there who may have additional solutions or may be more local and can offer direct assistance.

<p>Dear Adrian,</p>
<p>did you check with some other museum in your location if they have a nitrogen chamber?</p>
<p>You might try to reach out with some other conservators from cultural heritage. This method is very common for treating large object like furniture.</p>
<p>Here is a German company that offers a lot of great services and might know some contact in Sweden:

evacuating is riddled with pests, mainly the dermestid Trogoderma angustum, so everything has to undergo some sort of pest managing procedure before installation at the new place.</span></p>

that are sure to reside in the objects. The biggest object is a sperm whale skull measuring 275 * 590 cm at the base with a height of 215 cm.
