I tested the Digimon SE today to see about the R-4xx TP charts. to answer your question.
I pulled them randomly out of a box from production.
30.6 Bar = 52 deg C
43.3 Bar = 67 deg C
46.1 Bar = 70 deg C
And for fun I took it up to 50 Bar (725 Psi)
29.2 Bar = 64 deg C
21.2 Bar = 50 deg C
5.5 Bar = 5C
They seem to be testing well against my tables. So I checked my tables to see if they all were correct. So far, everything seems to be spot on.
According to Carriers white paper on Puron we are very near the critical temperature of the refrigerant at 50Bar so....
it looks to me like we have gone as far as we can with the R-4xx series of refrigerants.
Expat your post isn't covering what I'm talking about
Can you post a pic of a close up of the display showing the pressure and saturation temps of the high and low sides simultaneously like you have it connected thru the center port?
