Hi All,
In reference to the comments about blazing sun, would the use of thermal fumigation be a more energy effective and practical option rather than trying to accommodate a freezer outside on a hot day? This is of course providing that the objects would not be damaged: https://museumpests.net/solutions-heat-treatment-2/.

Hi Joan, We have been using a Liebherr upright freezer (modell GGPv 6570-43) over years for IPM purpose. It maintains a constant temperature of -20°C and is made entirely of stainless steel. I can't say for sure if it's good enough for storing photos and films, but I think it is. best regards V o l k e r H i n g s t Diplom-Restaurator Volker Hingst IPM-Koordinator --------------------------------------- LVR - Archivberatungs- und Fortbildungszentrum Technisches Zentrum / Papierrestaurierung Ehrenfriedstr.19 50259 Pulheim Tel.: 02234-9854-236 Fax: 0221-8284-2479 E-Mail: mailto:volker.hin...@lvr.de Internet: http://www.afz.lvr.de/ Von: 'Bacharach, Joan' via MuseumPests <mailto:pestlist@googlegroups.com> Gesendet: Donnerstag, 13.

Would appreciate hearing what type and make of upright freezers folks would recommend for cold storage of film and similar materials. Thanks so much!

This occurred in south-central Wisconsin in late May to mid-June, with outdoor temperatures exceeding 90 F on some days. We had a high volume of large objects (furniture size) that needed immediate treatment, so we rented a large freezer semitrailer and parked it on our grounds for a month (padlocked, refueled several times—no electricity needed). The trailer maintained temperatures between roughly -12 and -23, which we confirmed with two Bluetooth HOBO monitors. Despite being parked in full sunlight, the trailer was able to cool down to those temps very quickly, and then acclimated to ambient temperatures gradually enough upon treatment completion so as not to damage artifacts. To answer your question, I think your plan is feasible with the right budget. Free-standing outdoor freezer units are out there in the market.

We rented an 8 x 20' Walk in and had it parked at our loading dock. We had a padlock on the door and we have rotating Security. It was in the hot sun on concrete and it worked very well, though I think shade would be beneficial. We had a Bluetooth thermometer inside to monitor so we didn’t have to open all the time to check. Maybe you could slowly raise the temp of the freezer until it reaches Gallery temp? You need to have an electrical source that it powerful enough. Our electricians were able to put in a new breaker for it. Cheers!

We do not have interior space for one. I am thinking a shade pavilion overhead to cut down on blazing sun on a concrete pad with security fencing and cameras. Cutting it off to wait for acclimatization of the objects. Is this a terrible idea or possibly doable? Joel Voron Colonial Williamsburg Foundation Conservation Dept.
