    Re: Ultra low temp refrigeration

    ULT Lab applications usually include immersion or dip coolers, cryo-baths & ULT recirculators...most of which employ "cascade systems" in order to achieve -90°C etc.

    Basically, this means one fridge loop cools the next.

    if you google "cascade refrigeration" etc. I'm sure you'll find some papers etc. that explain the theory in detail. etc.

    My advice.....you'll need a good vac pump & charging scale.... & shed loads of armaflex
