[NHCOLL-L:4171] RE: call for IPM freezer specifications

[Codispoti, Burt]

We are just about to purchase a chest freezer for this purpose.

 

I found instructions on line for modifying a home unit, but have no one
willing to do the modifications. :-(

SPNHC NEWSLETTER Vol 7 No. 2 Aug 1993 p.4 by Ann Pinzl

 

We are short on funds, and hoping that we won't have to buy a commercial
unit.

 

One appliance repairman suggested just bypassing the thermostat, but I'm
worried about the unit getting damaged from running constantly.

Although, this was the advice given in WAAC NEWSLETTER Vol. 16 No. 1 Jan
1994 pp.26-2 [sic] by Lisa Mibach

 

I would love your advice. Please copy me with your replies!

 

Thanks!

Subject: [NHCOLL-L:4169] call for IPM freezer specifications

 

Hello all,

(Apologies for cross-posting) 

 

The IPM working group treatment subgroup is looking for examples of
freezer specifications from various institutions. Our hope is to compile
these specifications and post them on the museumpests.net site as a
resource for institutions looking into purchasing freezers. This
information would accompany fact sheets already posted about
recommendations and procedures for low temperature treatments, which can
be found on the http://museumpests.net/tools/treatments.htm (along with
fact sheets for other types of treatments). 

 

If your institution has a freezer you are happy with (or if you have
cautionary tales of freezers you have not been happy with) it would be
enormously helpful if you can find the time to put together the basic
specs. We can edit and compile them for posting. We won't use the name
of your institution unless you give us permission but your location will
be helpful information - i.e. country, and if US what region. . 

 

Here is the basic information we are looking for, based on the
recommended minimum temperature at 20 degrees below 0 Celsius,
maintained constantly so that cycling (as in "frost-free" freezers) does
not bring freezer temperature above that. 

 

Type - i.e. chest freezer, walk-in

Brand 

Model

Size 

Price

Year purchased

Brief description of capabilities - lowest temperature capable of
reaching and maintaining

Have you had adjustments made to the freezer so that it can maintain
adequate low temperature?

How do you monitor the temperature? Are you doing any independent check
of the temperature (e.g. dataloggers) and if so what equipment are you
using?

Comments on maintenance and any other related experiences

 

 

An example can be found on http://museumpests.net/tools/treatments.htm

in the posted document "Pest Treatment Case Study: Low Temperature Pest
Management Treatment at the Smithsonian National Museum of the American
Indian "

 

Please send your information to me at the address below.

 

Thanks very much!
