Hmmm I dont have a r420 on my refrigerant list. Thats normally pretty good to.

[subzeronick]

realy

[subzeronick]

any info on it would be nice i have had a little bit of a hard time tring to find temps

[n00b 0f l337]

Yep nothing past r417 in the r4 hundreds on my list.
You sure its r420? I'm not finding anything elsewhere either.
Personal favorite for single stages on my behalf is r507a with an oil movement additive like r290 or r134a.

Wait got you something;
Its made up 88/12 r134a/r142b.
That probably puts boiling point between -10C and -26C. More towards -26C or so. Decently high mass; seemingly easy to condense. Probably quite decent for high capacity.

humm ya i can post a pic of the tank

[subzeronick]

any good?

[subzeronick]

i know i an going to sound noob on this one but how i post pics do i fist have to have them on a web site frist ?

[n00b 0f l337]

Maybe decent, why not give it a shot. R507a would be betta no doubt.

Search google for imageshack and use that service, then use the link provided for forums and such, not the thumbnail though.

Sometimes called R-420. Seems to me the PT tells me it is more of med to high temp refrigerant. Nothing wrong with that. I would think straight R-134a most likely will work better though. Those odd numbers in 4xx ranges tend to be R-11/R-12/etc interim replacement proposals.
