CO2 Regulator "normal" operation

[Tricky Dicky]

What unit of pressure is psa? Never heard of it. The regs usually use bar, psi or kPa or combinations of those. Mine has bar and psi on it.

My bad, I should have put kpa.

 

[Tricky Dicky]

Do regulators slowly/smoothly release co2 when the pressure drops in a 19l keg head space or is it more of a short sharp burst when the pressure drops, how sensitive are they usually?

 

[Rocker1986]

They just release gas until the pressure is back to where it was before. I usually find it's a pretty nondescript event. You pour a beer and hear it gas in for about 10-20 seconds after and then it stops, however the longer it sits on the gas the less it does this, at least with any noise attached. I only notice it when the keg is quite full and hasn't been on gas very long i.e. has only just reached the carbonation level I'm after. When it's been there a while I'm sure it still adds a bit of gas but it must be a lot less because you don't hear it making any noise.

thanks for that.

What if you attach a check valve? There would be any back pressure to read from?

I've got check valves on my manifold, and also a non return valve along the line that runs from the regulator to the manifold. It doesn't seem to affect anything like that. The back pressure would be less than the pressure set on the regulator anyway, otherwise it wouldn't be sending gas into the keg at all.

When I do notice the gas being replaced upon pouring a beer, it always starts making the noise pretty much as soon as I begin pouring the beer at first. After another week or so on gas, the noise doesn't start until about half way through the pour, and after another week or two I don't hear anything much at all. And then it splutters everywhere because the keg blows dry.

Better buy up on the cheap co2 bottles in Oz while you can

Very cheap - 2.6kg co2 for $69 using S4OFJULY code at kegland atm.

 

[Rocker1986]

Well mine's good for another 10 or 11 months... it'll probably be offline for a while itself while we look to buy a house and move around the end of the year/beginning of next year.

Maybe they could draw some of the excess CO2 from the atmosphere that they're all talking about and use that instead

Maybe they could learn from coopers brewery and prime their kegs instead crisis solved.

What crisis? The best UK beers don’t require extraneous CO2, they are pumped or gravity dispensed.

Coopers brewery learned that from UK breweries.

Well there ya go an inflated article then. There is always a way around it.

I thought the breweries used the c02 from fermentation to carb the beer. It's siphoned off, scrubbed to remove odour then used to carb. It's the dispensing of beer and soft drink industries that use it.

That's corret. I cant see you guys getting a cheaper deal EVER again.

The price is already cheap at $89 https://www.kegland.com.au/co2-gas-cylinders-2-6kg-full.html

But then use the discount code and it's insanely cheap. Starting to get close to the cost of a refill.
