Re: [EXTERNAL] [PestList] Question about upright indoor freezers

Hi Jane,

Solar bagging could be a good alternative.

I think there are also merits to satellite/outdoor heat treatment units, 
especially if the environment is in a warmer climate. A consistent power source 
is a concern for both low and high temperature treatment, as is maintaining 
insulation. A specialized, permanent outdoor heat chamber could work. 
Otherwise, relatively low-cost mobile heat treatment units (like a bedbug tent) 
usually need ambient room temps of around 70-75 F to start, multiple power 
circuits, as well as lots of space for air circulation and venting around 
objects. This can be difficult to accommodate in an enclosed building, so heat 
treatment on loading docks or outside on hot days with a mobile heat treatment 
unit might be better than doing this type of treatment indoors. (It's not easy 
to maintain building-wide optimal preservation temperatures when a giant 
oven-tent is releasing heat into a room!) If using mobile heat treatment 
equipment, constant surveillance throughout treatment may also be necessary to 
avoid fire hazards.

Overall, I find that low temperature treatment can more safely cover a wider 
variety of artifacts in my own organization's collection than heat treatment 
can (ex: many electronics, waxes, and all photos/film cannot withstand high 
temperature exposure, and many plastics warp), but this may not be true for 
other institution's collections.

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:

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

Would appreciate hearing what type and make of upright freezers folks would

Hello Joel,

 



Our staff recently experimented with outdoor freezing. 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. (EX:
