Carbon Dioxide – Consumption

We are often asked how much carbon dioxide is used, and the simple answer is “it varies.” There are many factors that influence this, such as temperature, water hardness, type of machine, when it was last serviced, etc. Of course, user preferences also play a role. Some prefer extra carbonation and like to have the saturation set to the maximum.

The type of faucet, settings, and similar factors also come into play, but generally, it is estimated that approximately 3–5 grams of gas is used per liter of water to be carbonated. In our own tests, we find that 3.5 grams per liter is a reasonable estimate.

Simplified Calculation

If you want to translate this into the amount of carbonated water per CO2 bottle, it would look roughly like this:

• 3.5 kg lasts for approximately 1,000 liters

• 7.5 kg lasts for approximately 2,000 liters

• 10 kg lasts for approximately 3,000 liters

If you further calculate based on a standard 20 cl plastic cup, the following number of cups would be produced:

• 1,000 liters lasts for approximately 5,000 cups

• 2,000 liters lasts for approximately 10,000 cups

• 3,000 liters lasts for approximately 15,000 cups
