Suggested 02 Bank Storage Bottle?

[rjack321]

Why not a J from a gas supplier? And a whip? It's what I used before getting a booster on top of it.
Safe, minimal investment.

50l times 200bar is about 5000-6000 whippable litres of O2 - give or take 60-100 HOURS of time on the loop before you swap the cylinder, without any booster. With a booster it goes to about 9000 litres of O2 - LOTS.

I bought my own J now and swap, but most providers will rent for a very reasonable rate and I used to do it.
The only investment is the whip with O2 J appropriate adapter.

Just in fuel and driving time it paid back in 3 months for us.


EDIT: About the whip - I would STRONGLY advise a precise digital one. And reading on precautions and speed of O2 charging, especially when feeding from a full J, if not gas blender training.

O2 is not supplied at 200bar here. More like 140bar on a good day. So that little AL13 won't even be 2/3rds full.

Yea, but just because _we_ know that, doesn't mean the local gas monkey would, I was looking for easy when I got started. Thanks for relaying your experience. I might try taking my personal HE T bottle in next time and seeing if they will fill/exchange it. If so I'll start gathering bottles and just not renew my lease.

Don't forget to announce yourself, maybe bend over blowing yourself, a trumpet tune
"I want some gas in these here bottles that I'm not renewing the lease on gas monkey"

That's sometimes what I do

AL13?

J (50 litres) is delivered at 220 bar here, so around 388 cubic feet.
I was talking about having a bank of O2 that even without a booster can last 3-6 months, not a deco stage.

You can get 300 bar in Europe, but it's problematic, expensive, not available from everywhere, not my supplier anyway.
I would generally stay away from 300 bar O2 in hobby environment anyway. 220 is scary enough.

It sounds weird that bulk gas suppliers wouldn't have 220 bar bank tanks available, that's how it's produced anyway.

The subject of the thread was a bank tank.
I believe the closest equivalent to our J on your side of the pond is the S tank, so maybe ask around for an S of O2.

I have never seen or heard of a bulk gas supplier stocking 220 bar oxygen bottles. Both Airgas and my local gas company do offer it as an option and occasionally supply it to some customers. It is prohibitively expensive. Both of them hire my booster to fill them as neither have anyway to take oxygen over about 2800psi.

You are fortunate to get that option. This side of the pond, you only get a touch over 2000 PSI. from the gas supplier. That's what the common bottles all the gas suppliers are using and all they rated for.

You probably get a decent 240V at your electrical outlets as well? We only get 120V. You just get more than we do.

I just know you could get a much, much higher pressure, which would maybe let you get multiple fills to 3000

Please remember the limited compressibility of gas.

Past a certain point (like 240 bar) the actual amount of gas does not grow with the pressure. Hence, 400 bar is much less than twice the 200 bar. Go with the bigger bottles.

I am genuinely surprised at that... I was under the impression it's us on the wrong side of the pond always restricted and dying under red tape, looks like we've found an exception.
Sorry to hear that. In here (and most of Europe) 220 bar of O2 in a J (your equivalent would be around 388cuf) is not really something special. 300 bar is.

I just answered above - I know nothing about US so this is enlightening.

Gas (O2, air) cannot be compressed above 240 bar?

It doesn't behave as linear above that. Pressure is no longer matched to volume. Doubling pressure no longer doubles volume.
