Carbon Dioxide Regulator

The bottle contains pressurized carbon dioxide, so it needs to be regulated during delivery. Attached to the bottle is the regulator which has a readout of the current pressure which is initially about 700 psi and about 5000kPa of pressure. This is a new bottle and is what is expected with a fully pressurized bottle. However, depending on the temperature this can increase or decrease the pressures that are shown. What is presented is the “normal” or room temperature levels for comparison.

Another important aspect of the regulator is to control the flow of the carbon dioxide during delivery. If you look close above the pressure gauge a green plastic ball can be seen. The carbon dioxide is flowing and it is set at a rate of 5 cubic feet. The key is to keep this below 10 as any higher and the regulator will actually freeze due to the cooling effect of carbon dioxide as it goes from the high to low pressure state.

The flow rate is adjusted by the black knob that can be seen on the left side. This requires fine adjustments moving it a little bit can massively change the flow rate so be sure to check the flow rate to avoid freezing up the regulator valve.
