I am openning a shop and want to hav a fill station. The LHBS has a pump system that is very pricey. I've seen posts of people filling it partially by pressure, then dumping some CO2 to freeze the tank then finishing the fill. Anyone have experience on doing this. Does it work? How much CO2 will I loose? And how much of a 50 lb cylinder will I get out?

Thanks

I haven't the foggiest idea what you are talking about.

I know of some off-road shops that have a large donor tank and freeze the "donee" tank, connect with adapter to flow liquid from donor tank until equalized. Repeat cycle.

Haven't heard of loss complaints, but you max out at 70%-80% of what you get when filled via gas company compressor method.

So you won't quite get 5 lbs in a 5 lb CO2 tank using the freeze method?

Excuse me for asking for clarification. You seem to have the right attitude for running a LHBS (condescending, know-it-all).

Good luck.

Not according to the folks that do it and are having it done. They charge less for a fill though, of course you're getting less too. You do get diminishing returns and won't be able fully use up your donor tank for filling.

They also might be myopic regarding hydro dates.

FWIW.... Shows how to CHILL and then FILL a CO2 tank.

Actually, I don't know it all. That is why I am here asking questions. I didn't grasp that you were asking for clarification and was offended. I guess I shouldn't be as you can not determine tone from a thread. Anyway no big deal. Have a good one.
