Recovery of R23
Hi
Does anyone out there know the best way to recover a large amount of R23 other than just using a chilled evacuated high pressure cylinder?
I cant find a recovery pump that is suitable for high pressure gasses of the type of R23,R508b etc
Thanks
C

Re: Recovery of R23
Good question Chris, struggled exactly over this problem end last year and for me, it's impossible to do this.
You have to vent it to the atmosphere unless you recover it to several cylinders and pressurize those all to 20 bar.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Recovery of R23
You may already have solved the problem, but anyways here is a way to recover the most.
if possible freeze your recovery cylinder to the lowest possible, if you have access to low temp freezer, then use this, alternative a cold room.
the trick is simply to let the refrigerent run from the warm unit to the cold cylinder, best result is if you can have your cylinder keept in the cold, it will take some pretty long time
it a long distance i on site simply make !/4 pipe between
