Hi everybody!
I'm new at this site. I have bought a immersion chiller for going down to -135 ºC. It lost the gas (a mixture of R170 and R404a in unknown proportions) due to the vendor didn't appropriately fit a nut. Now, they don't want to send nor sell the gas -they must think they have a big secret;). Do anybody know any information about how determining the correct proportion? I have read in a post of this site (http://www.refrigeration-engineer.com/forums/showthread.php?1262-Autocascade-refrigeration-system-design-verification-needed&) somebody (DaBit) who have tried to do something similar.
Thanks
