Corny keg pressure

[Mtrhdltd]

In my opinion, his 1800 psi is still too high even if it’s beer gas. Here is a picture of my 75/25 nitrogen/CO2 blend sitting at 66°. This tank is nearly new and reading 1400 psi (bottom gauge)... I don’t think it was ever much above 1500 when it was new.

No experience myself, so I was just guessing.

Its possibly my bad as i purchased it on the website as i was brewing lager i assumed this was correct. Do you think if i removed it and purchase 100% co2 by tomorrow my kegs will be ok without gas pressure

If you disconnect the kegs, they’ll be just fine until tomorrow. I just looked up that gas... you’re not in the US, are you?

No im in ireland it could be different systems but will the beer gas have a negative affect being used temorarily

I would keep it hooked up until your tank of pure co2 arrives.

Here’s a photo of the co2/temperature chart everyone keeps mentioning.

 

[Jamie02173]

Thanks for all the comments guys ill leave it overnight and fly over and get it before work and connect again. Im learning as i go why question is confusion regarding temps to keep my co2 tank. Is the main problem that changes in temperature will affect the psi adding more pressure making it unsafe? My plan was to keg the beer and leave it at ambient winter garage temp until tomorrow evening and i should have new gas and a fridge to store both kegs. So my final question gas inside or outside the fridge?!!

 

[GilSwillBasementBrews]

Gas inside or out won’t affect the psi pushed through the regulator.

So im not sitting on a bomb lol

No the concern over pressure of the beer gas tank was due to the pressure gauge being excessively high if the bottle contained pure co2.

Is dat the one on the left im trying to find some videos on psmi and reading both dials as there is four readings 2 red and 2 black on each side

 

[GilSwillBasementBrews]

The red numbers are PSI readings. The black are BAR readings.

 

[GilSwillBasementBrews]

You want to follow the red readings.

 

[GilSwillBasementBrews]

And yes the gauge in the left in your pic is the tank pressure. The other gauge is what your pushing to the keg.

Sorry, in the USA pure c02 bottles are rated at 1800 psi. I jumped to the wrong conclusion early on.

What should i do to lower

Cool juat to make sure im not too high on the left if you think i need adjustment they will sit overnight at

Any advice helps im watching videos now so maybe my next step is figuring out gas line lenght and will this affect psi

There’s nothing you can really do to lower the reading on your tank pressure gauge.

You’ll be fine as long as you swap tanks and take care of it tomorrow. You can’t adjust that reading.

Gas line length will not fix your problem. Line length is only applicable on the liquid side to counter balance the pressure in your keg so your beer doesn’t foam when you pour it.

The line length will not affect your gas PSI Line length matters on the liquid out side. If your pours are too carbonated longer lines can help reduce excessive foaming.

Thanks a lot guys this was very helpful and might have save my brew! I will disconnect the 50/50 in the morning and reconnect with 100% co2 when i arrive home from work and hopefully i will have my fridge and create my kegerator.. use may here from me again if i run into any struggles!!

 

[GilSwillBasementBrews]

Just make sure to purge the gas in the keg already, when you hook up the pure co2 mix. You will want to remove as much of the nitrogen in the headspace as possible. It should be negligible, but you want more co2 in the keg than nitrogen as the co2 will dissolve into the beer carbonating it. The nitrogen will not dissolve into the liquid.

Was thinking that alright! ill make sure to purge it plenty with co2 and hopefully be on the right track, and once i have my keg in the fridge i will correct the psi according to the temp chart. The co2 cannister will be outside the fridge on ambient temperature. Do you think that will be a problem?

 

[Jamie02173]

I posted a couple more threads. Any shared knowledge much apreciated!

 

[GilSwillBasementBrews]

No. I keep mine outside my fridge as well.

 

[GilSwillBasementBrews]

The only other thread I saw was about gelatin for fining and I have no experience with using gelatin. I just let gravity/time do my fining lolol

 

[Beenym88]

I have filled the kegs and set the pressure at 18 psi (what i think irls 18 psi for now) do you think i should bring it down to 12psi?

I hook my finished beer up to the CO2 and blast it at 30psi while rolling it on it’s side for a full 5 minutes. Then I put it in my chest freezer for 3 hours and it’s got good carbonation and is ready to go every time. This is the burst carbonation method.

I might try that without fear of an explosion! Do you disconnect the gas while u roll it?

 

[McKnuckle]

I think you should try to keep the gas connected and let us know how that goes. Take pics.

Ive had an issue myself i got the wrong gas sunday and i have been busy working since. I finally got the gas today and my 2 kegs of beer have been in the cold garage since sunday so im hoping they will be ok.. possibly still slightly fermenting

They were fermented 2 weeks on sunday so i transfered from primary to corny keg and they have been without gas pressure since sunday. Im hoping this will not be a major problem

The kegs have a pressure rating of 130psi so there really is no issue at all with 30. While I’m rolling it I keep it hooked up then disconnect it when I put it in the freezer. It’s not an exact science but it’s never failed me just be sure it’s at at least 30.

I generally put two kegs on CO2 at serving pressure 10PSI. Usually I'm drinking from the first keg, the second keg catches up in a few days.

I keep the CO2 bottle on the door. It is a tight fit, but it closes smoothly. I reversed the regulator to get it all to fit inside the 4.4 cubic foot mini refrigerator.

I mark the side of the keg with black electric tape - a long tape to denote the long dip tube side, a short tape to denote the gas in side. This would correspond with the tube lengths inside the keg. Makes it quicker than looking for the notch on the fittings!

 

[Beermeister32]

I have a number of these set up, here is one of them used as a temperature controlled fermentation chamber.
