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>

<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:
