I personally didn't believe cryotec when I read his threads he never answer direct questions and was vague on the rest. all we got was some blurry pic of a bunch a junk in a box. I wish some would find the autocasade with the pink insulation around it.I believe from what Iwas told that it got to -80c r23 territory. This is the first time I dissed someone seriously like now. but all he did was post old autocascade drawings . his work that was pictured was far from pro. and all he was doing was doing to the moderator here who owns a polycold was adding argon to the professional built polycold to get low temps with no load in my opinion. I called Bull,sh*t in the thread and still stand by it till proven otherwise,then I will apologize if proven wrong.....I could go on to explain more of what I know about his work but I'll stop here.

cryotec is welcome to come back and teach you all how to build the -150 autocasde he was credited for but never shown.or the possible -180 iirc he mentioned. he disappeared when me and other older members kept asking for pictures and answers to specific questions. don't count those post as valid. until proven and backed by pictures.

people tried this before I think the user I'm thinking of it was his second time, remember the guy with the blurry boxes of stuff he claimed was advanced cooling items,until un-known to him FUGGER worked at pictographics and could enlarge the blurry pictures and clear them to show a bunch of junk in the basement.Is that thread also still around.

science its not so until it can be reproduced and verified independently
