I don't have one, but you can watch this video on it and see what you think.

Good one rundawg. I didn't expect a video. That answered my question. I wonder how fast it would be in ice ? Maybe I should make my own in a cheaper version. Like some 3/8" copper coiled up.

Others have done that with success.

You can do something really close to this with a small receiver... I use a small recovery cylinder on the outlet of the machine with the dip tube port to the larger tank.

Also too, when it is stupid hot outside I will sub-cool the bottle half way through filling it... Just use the recovery machine, vapor from the bottle into the machine, the machine to the liquid port of the bottle....Takes about 10 minutes to literally drop the bottle temperature to ambient..

Just coil some 3/8" tubing around a nitrogen tank. Stick some 1/4" flare ball valves on it and you have the same thing as that "molecular transformator" for a fraction of the price. Well worth the effort to make it, instead of trash can full of ice you just lug a 5 gallon bucket full of ice!

Made one myself awhile back. 10' 3/8 cooper coiled up with valve on both ends. 5 gal bucket 2 bags of ice. Works pretty good. Shoved 25 lbs of 410A into a recovery tank on an 85 degree day. Tank pressure never hit 225. Cut recovery time in half. Make sure you are weighing the cylinder though. Don't wanna shove 60 lbs of 410A into a 50lb tank.
