Liquid CO₂ Gas Cylinder — steel cylinders filled with liquid carbon dioxide
The Liquid CO₂ Gas Cylinder range from REAL GAZ covers seamless steel cylinders in which carbon dioxide is stored as a liquid under its own vapour pressure, about 57 bar at 20 °C.
Because the gas liquefies, a single bottle holds far more product than a compressed gas cylinder of the same size.
Because the gas liquefies, a single bottle holds far more product than a compressed gas cylinder of the same size.
Cylinders are made and inspected under ISO 9809, EN 1964 and the TPED regime, and valves follow EN ISO 10297 practice.
A Liquid CO₂ Gas Cylinder is normally filled by weight, not by pressure, because the pressure of liquid carbon dioxide stays constant until the liquid is gone. Typical packs are 10, 20, 40 and 50 litre water capacity, holding roughly 7.5 to 37 kg of CO₂ depending on size and filling ratio. Dip-tube cylinders deliver liquid, while standard cylinders deliver gas and may need a heater to avoid freezing at the regulator when drawn quickly. We label each cylinder with grade, net weight and test date, and exchange or refill empties on a rotation that keeps your stock from running dry.
Handling rules are simple but important. Move cylinders with a trolley and valve cap fitted, keep them away from heat and never lift by the valve. Carbon dioxide is heavier than air, so use cylinders only in rooms with good ventilation. Return empties with a small positive pressure left, which keeps moisture out and protects the next fill.

🏭 Where Liquid CO₂ Cylinders Are Used
- 🥤 Draught and soda systems — a standard cylinder feeds bar dispensers and small bottling lines at a steady working pressure;
- 🌿 Greenhouses — gas-phase CO₂ enrichment raises plant growth rates in controlled-environment horticulture;
- 🔧 Workshop welding — mixed or pure carbon dioxide serves MAG welding of structural steel;
- 🧯 Fire protection — CO₂ cylinders charge extinguishers and local flooding systems in electrical rooms.
