Dear all,
I have been reading your forum and have read a lot of useful information. I am also working on the production of ultra-low temperature chambers. Until now we have reached -85C with a two-stage cooling system. The first stage is cooled with water at a maximum temperature of 45C, condensation of the first stage. The first stage evaporates at -30C, which is the condensation of the second stage, which evaporates at -85C.
We want to develop an application with -110C so we are wondering if we should continue with the same principle - if there is some gas mixture that we could use to gain -110C ? Or would it be better to start all over again and go for the autocascade system ?
Thank you,
Ivan
