Co2 : Using 2 KG Fire extinguishers

[EssexBrewing]

What that means is you can buy a bottle that will deliver CO2 as a liquid or a bottle that will deliver it as a gas. The actual bottle contents are the same.
The only difference is the dip tube.

No they are not. You can buy it in liquid or vapour form. As stated clearly on BOC's website.

ye and the cylinder for vapor will be a one that takes a much higher pressure. steel, like pub cylinders are.
the fire extinguishers are mostly aluminum hence wont take as much pressure

Around 230 bar if I recall, so a 15l cylinder will hold 3450 litres.

The CO2 is always liquid inside the cylinder as the pressure forces it into a liquid the only way for it to be purely gas is when its nearly empty. from the BOC link:
- Cylinders of both liquid and gaseous carbon dioxide are available from BOC. Dip tubes are used in liquid withdrawal carbon dioxide cylinders to extract the liquid from the cylinder. The tube runs down the centre of the pressurised cylinder and draws the liquid up through the valve. To identify these cylinders, a white stripe is painted down the length of the cylinder.

It states the liquid has a dip tube to dispense liquid, therefore the gas does not have a dip tube so dispenses gas even though the CO2 in the cylinder is liquid.

Well done! I was working up to try and explain this:



Which assumes I could understand it too (well, I can't!).
