CO₂ supply
Food-grade CO₂ supply for carbonated filling projects.
Carbonated filling uses CO₂ both as part of the drink and as a process utility, so the gas supply, pressure control and safety arrangements should be reviewed before a filler is specified.
A carbonated filling project needs a suitable CO₂ supply for product carbonation, package purge or pressurisation, and pressure control around the filler. The correct gas grade, regulator arrangement, cylinder or bulk supply, ventilation and operator procedure depend on the drink, site and machine scope.
Lancing can review the machine-side requirements, but the buyer should confirm food-gas supply, site storage and safety arrangements with competent gas and safety providers. Public UK guidance from the British Compressed Gases Association notes that beverage dispense gases used in drinks are food gases, while HSE guidance explains that carbon dioxide is a workplace hazard at elevated concentrations.
| Product carbonation | Confirm whether CO₂ is added before filling, by a carbonator/mixer, or through an existing site process. |
|---|---|
| Package purge or pressurisation | Confirm whether the filler uses CO₂ to purge or counter-pressurise the bottle or can before product transfer. |
| Gas quality | Use a suitable food-grade gas supply for beverage contact; final responsibility should sit with the gas supplier and the food safety system. |
| Ventilation and detection | Review CO₂ accumulation risk, especially in low areas, enclosed rooms or cellars. |
| Pressure equipment | Confirm regulators, hoses, valves, gauges and written safety procedures as part of the site risk assessment. |

Buyer questions
Questions buyers ask about this topic.
Does Lancing specify the gas supplier?
Lancing can state the machine-side requirements and review the intended supply route, but the gas grade, storage, delivery, regulator selection and site safety arrangements should be confirmed with the gas supplier and competent site safety personnel.
Can any CO₂ cylinder be used for beverage filling?
The buyer should use a suitable food-grade beverage gas supply. Cylinder ownership, identification, storage and safe handling should follow the gas supplier’s instructions and the site’s food safety and health-and-safety systems.
Why is ventilation part of a filling-machine discussion?
CO₂ can displace oxygen and is not detectable by smell. Because carbonated filling may use CO₂ for purging, pressurisation and product preparation, the site layout, ventilation and operator protection should be reviewed before installation.
