My nitro tank finally went empty. Unexpectedly. It's the first run on that tank. I believe it's an "80" cu ft tank. I think gas/vapor is measured in cubic feet and liquid gas is by weight, like propane. I know "nitro" beer gas 70/30 mix is supposedly just pressurized vapor in the tank, not in a liquid state.

Anyway, it's about a 4-5 foot tall tank. I think I got maybe 5-6 kegs out of it? I didn't keep track when I switched from CO2 to nitro on my RIS stouts.
 
Seems quick considering I've put that many kegs through my nitro blend tank that is much smaller.. maybe a little bigger then a 5lb co2 tank...I assume you're carbonating your beer first on standard co2 then switching it to the nitro tank?
 
That could be about right...maybe? I have a 40 cu ft and that normally lasts me 3+ kegs? I guess I never really counted.

Hoping @day_trippr will chime in with wisdom on this. I generally lean on him for all things nitro.
 
Yes, I try to carb first on CO2.

Actually, my first couple nitro kegs I probably was normally carbonated and aged before serving on nitro. Had issues with foam...go figure...lol

Only the last couple kegs I actually aged and had bleed down to 1-1.5 volumes before serving on nitro.

That is super small for a nitro tank. details? I didn't even know pre mixed beer gas was available from suppliers in anything less than an 80 CF tank.
 
For reference, my 40 cf steel beer gas cylinder is ~21" tall by ~6.5" diameter. It typically dispenses 11 to 12 five gallon kegs between fills, which usually carries me through around two years (my stout being an almost 12 percenter doesn't take much to do the job ;)). The current fill came in at 1600 psi and has dispensed 7.5 kegs so far, with the gas pressure now at 900 psi. Seems to be on track...

Cheers!
 
My 80cf tank also managed about 5 kegs - only because I lost >75% of the gas to a loose fitting.
I recently moved everything to a new keezer and re-did all the CO2 lines...I thought it might be a leak.

For what an 80cf cost to exchange...5 kegs ain't worth it.
 
That was my initial thought, after looking at my tank last night when I got home from work and looking at my notes on nitro batches it is the 40cuf size and I'm currently on keg 9 and the gauge is starting to get close to the red.
 
I drink stout on nitro all the time. Last year I filled a 20 cf and a 40 cf tank and it lasted thru 8-10 5 gal kegs. Guessing you get about 1-2 kegs per 10cu ft.

I use 2 tanks so I can be chill on the refill - I got a backup.
