hey all. im a 25 year supermarket refrigeration veteran and have been asked to help out a local engineering firm to resurect an older thermotron unit. it like most was r-13 and r-503 origanally. now it looks like r-23 and r-404 would be the gasses of choice. i have numerous questions for anyone who has input on such issues. expansion tanks,oil return,total volume of r-23 as a vapor equation for the expansion tank... ect. and if u didn't notice i am computer illiterate haha. my e-mail is sadie333z@gmail.com

Just heard on the news today that HFC's will be banned soon.
I give em another 4 years and they'll all be gone.

I'd seriously look to one of the newer HFO type of refrigerants.

As for the circuit itself, loads of people on here will help, just
ask what you want.

Oh and welcome :D
