How to fill the CO2 cylinder for the Aquadream carbonator? Small amounts of gas.

Question

Good morning, I bought a set for filling the cartridge for a soda stream carbonator, I have a mother bottle and a transfer valve. The problem is that only about 40 grams of co2 is injected into the cylinder each time, and then very slowly it goes down to 2 or 3 grams at a time, so I disconnect...

If the valve in the cartridge is one-way, it often fills slowly. What`s more, if you want to do it too quickly, it may get completely blocked.

Labatek · Answer

The valve in the small cylinder is bidirectional

With pin or flat?

Is the mother cylinder in the correct position? You are to inject the liquid phase into a small bottle. If the large cylinder is siphoned, it must stand vertically, and if it is without a siphon, it must be turned over to transfer liquid carbon dioxide. Before transfusion, the small bottle must be completely emptied by pressing the pin (preferably wearing thick gloves to protect against the cold) and it is a good idea to keep it in the freezer for an hour.

Labatek · Answer

The matter had already been clarified, it turned out that the large bottle was almost empty, and since I had never used such equipment, I didn`t know about it - the seller informed me that the bottle was full, so it was obvious to me I replaced it with a full bottle and everything is fine, as it should be. Thanks for the answers.

Even Solomon cannot pour from an empty...

Hello. I have the same problem. He also charges me 40 gr.
I weighed the mother bottles. (6 kg) and it is rather full because it weighs 19 kg. And the empty weight on it is 12.55 kg. The seller assured me that the cylinder has a siphon. The valve on the small cylinder is also bidirectional - like the one in the photo of my friend. I don`t know what could be the reason why I don`t want to fill the right amount.

Maybe there is no siphon and you are only injecting some CO2 gas. Empty the small bottle completely by pressing the pin and try rolling with the large bottle lying down.

Hello. I have the same problem. The sodastream cylinder has a flat head. I managed to fill it once. The mother bottle is full. Help

Loker · Answer

How much can you do?

Marmiz1983 · Answer

Thanks for the instructions. Putting the bottle in the freezer for about 1 hour and turning the valve on the mother bottle very slowly helped. Regards

Hi. Today, for the first time, I filled two sodastream cylinders (two-way valves) from a larger cylinder with 2 kg of CO2. After weighing, the result was approximately 250g in each, and it should contain more than 450g. Where should I look for the cause?
I will add that the large bottle has just been unsealed.

Marmiz1983 · Answer

Did you freeze small bottles??

dzielnyzuszek · Answer

NO. Their temperature was +5

Marmiz1983 · Answer

Then try freezing it. I have a one-way valve and only putting the bottle in the freezer allowed me to fill over 420g.

gelob · Answer

describe the type of connection between the CO2 cylinder (does it really have a siphon?) and the sodastream cylinder. There are many different fistulas.

dzielnyzuszek · Answer

Another refill. This time after freezing the cylinder. The result is 317g, which is 25% more than without freezing. Thanks

bokun1983m · Answer

Hello.
If you don't want to freeze the cylinder, just pump some gas into it for about 3 seconds. Then, by pressing the valve pin, release the gas from the sodastream cartridge, which will cause the cylinder to freeze. In my case, this way I manage to fill 450gr of CO2 through the one-way valve. Of course, this has to be done very slowly. Regards

Is there any way to unblock the valve?

tdiabel1 · Answer

I have a question, I bought a large 8kg CO2 cylinder of gas, I fill 10-11 small cylinders and even though there is still gas in the mother cylinder, I cannot fill the next small cylinders completely as is the case with the previous cylinders. I freeze each small cylinder and I can easily load over 420g, but once I reach the magic number of 10 cylinders, I can only load 200g. The mother bottle is, of course, with a siphon. What may be the problem? From what I calculate after weighing, I still have half of the gas in the large cylinder.

stachu_l · Answer

What is the temperature of the large bottle then? By pushing the liquid fraction, the volume of CO2 above it increases, so some of the CO2 evaporates to maintain the pressure and cools the rest of the liquid CO2. Based on the number of cylinders you fill, I don`t think it`s for your own needs - do you have UDT qualifications? Do you check the technical inspection dates of the filled cylinders? Do you check their technical condition before filling?

tdiabel1 · Answer

Of course, it's for my own needs, I have a large family, so I also waste a lot of gas when everyone only drinks water, I'm certainly not doing it to earn money. And the cylinders are approved

stachu_l · Answer

By the way, such a popular cylinder is 8l and holds 5kg of CO2, so after filling 10 cylinders of 420g each and doing it without loss, 800g of gas remains - for one cylinder and some more. So the question is - is the cylinder 8l or 8kg? Firefighters say that 6 kg can fit in 8 liters: If there is a break between fillings and the cylinder equalizes the temperature, there should be no cooling effect of CO2 in the large cylinder (it will be compensated by ambient heating). If a large family comes at once with more than 10 bottles, fill 5, make coffee, talk and then fill the remaining ones.

tdiabel1 · Answer

The bottle has a capacity of 8 liters and weighs approximately 19 kg when filled.
10 small sodastreams, no problem, but then problems with filling begin. I weighed 10 bottles each and the large bottle lost just over 4 kg, so I still have about 4 kg. Even though I freeze sodastream bottles, unfortunately it only holds 200-230 g. The large cylinder is at room temperature, the valves in the small cylinder are two-way, those with small pins.

stachu_l · Answer

That`s about 6kg of CO2 So there`s less than 2kg left of the 6.
