Hi Joel, 

We do not have an external freezer - but have rented freezer trucks before 
when in a pinch. 

Consider heat treatment with controlled RH.  Heat can be incredibly 
effective - and it doesn't need to be very hot (50 degrees Celsius or so) 
and the dimensional changes can be less than if an object was frozen.  (eg 
going from 25 degrees C to 50 degrees C instead of 25 degrees C to -20 
degrees C).    Obviously depends on the material.

Subject:        [PestList] Walk in Freezer Question
Sent by:        pestlist@googlegroups.com



Does anyone have a walk-in freezer for cold treatments that is 
freestanding outside? 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?
