Hi Amy, That will depend on your environment and use. IF you are in an area that is high humidity it will be more often. I have a chest freezer that is not seeing a lot of action right now. It has been over 2 years since I defrosted because I do not need to open it often. It probably needs it now.

The reason you want do not want a frost free freezer is that it cycles through a warm (defrost) phase that reduces or eliminates frost build-up, thus reducing effectiveness in the use for pest control. The majority of freezers are of the frost free variety – but there are ways to disconnect the defrost unit without damaging the unit. Find an engineer or mechanic who knows how to do this. The down side is that you will have to do the old fashioned manual defrost at some point.

When selecting a freezer, it should be capable of reaching and maintaining minus 20 degrees F. It should also be a chest type freezer. When opened, it will not lose it's temperature as would an upright freezer.

Hello, At the National Library of Scotland, we have a quarantine space which doubles up as a disaster store, it’s hardly ideal but I think allocating space in acquired properties can be tricky. I’ve found that it can sometimes be difficult to state your case for fit for purpose quarantine spaces, as space can often be an issue in museums/libraries/galleries, which always need room for the expansion of collections, and in some cases it really can be a matter of making the best of what you have. In regards to the freezers, if you’re not using them too often, or don’t need to freeze a large volume of material, Foster Refrigeration have some good offers on freezers which you might be interested in. https://www.fosterrefrigerator.com/en-gb/products/cabinet/ecopro-g2-cabinets/double-door/standard-cabinet/ep1440h/10-166<https://linkprotect.cudasvc.com/url?a=https%3a%2f%2fwww.fosterrefrigerator.com%2fen-gb%2fproducts%2fcabinet%2fecopro-g2-cabinets%2fdouble-door%2fstandard-cabinet%2fep1440h%2f10-166&c=E,1,Qyjjxwra_eY4uDqA0X3Axh09gz59aYjtR_mu4xwVKuW5Pab1ab0PU1lvn4UWKZ0e_JkHRGnjQAwcsZjio9GgNGJRmfCFMMFz8cm6AeceXsrAuUyD4GLe_Q,,&typo=1> Let me know how you get on, as quarantine is something we are currently reviewing at the library, and any experiences people might have would be interesting.
