    newbie just trying to get a little help



    Hello

    I am trying to build a small(4000 cu-in) cooling chamber that gets to about -40C. I am having hard time time finding anything in that range. The best thing ive found is carrier products for cooling trucks. Any help at this point would be welcomed as this is out of my field and im not sure were to look.

    thank you

    Try google "ultra low temperature freezer" and you will find what you are searching for, Thermo Scientific will be among the top results and they do a couple of different models that might suit your requirements.

    Thank you for your reply

    We are not looking into finished units as much as into a unit we can place into our own chamber.
