Single-stage auto-cascade build

[tiborrr]

I think i'll need another 500mL can of polyurethane foam since there are still few gaps left to be filled







Added a bit of R-290/R-600 and got -79°C at 1bar LP/7.2bar HP:


Re-quoting myself:

Don't know, but do you think If I rather go a bit easier on the CO2 charge and add some R-1150? I think I could get into -85°C league with some positive back pressure, what are your thoughts on this charge?

@Pieter: Thanks bro, more about load holding abilities tommorrow!
@Sdumper: No problems buddy, i'll draw schematics of it, just remember to remind me about doing that from time to time

Best Regards,
