refrigerants for cascade system?
Hi, just new in RE forum... need some inputs & ideas regarding the recommended refrigerants in terms of performance for the cascaded system for extreme cooling application.
For Low Stage system, R-23 or R-508b?
For High Stage system, R-507 or R-404a?
Thanks.

Re: refrigerants for cascade system?
What do you call extreme and for what purposes?
There are lots of options to consider what about R744???
