15kg CO2 Cylinder – Carbon Dioxide Gas Take-Off (In-Store Only)

Pure CO₂. Serious Performance.

Our 15kg CO₂ cylinder operates on a simple, cost-effective deposit-and-refill system. Pay a one-off deposit on your first cylinder, then swap your empty for a full one each time — you only ever pay for the gas.

Why CO₂ Gas Take-Off?

Gas take-off cylinders draw CO₂ in its gaseous state directly from the top of the cylinder, making them ideal for precision dispensing and consistent flow rates. No liquid CO₂ splashing, no pressure spikes — just clean, controlled delivery every time.
