Compressed CO₂ Gas for purchase — pressurised carbon dioxide, ready to connect
Customers who want Compressed CO₂ Gas for purchase receive cylinders that hold carbon dioxide as a liquid under its own vapour pressure, about 57 bar at 20 °C.
Because pressure depends on temperature rather than contents, a gauge alone cannot show how much CO₂ remains, so we also provide weight data.
Because pressure depends on temperature rather than contents, a gauge alone cannot show how much CO₂ remains, so we also provide weight data.
Equipment is selected under EN ISO 2503 for regulators, EN ISO 10297 for cylinder valves and ISO 9809 for vessel construction.
Many buyers ask how long a cylinder will last. As a rough guide, one kilogram of CO₂ yields about 540 litres of gas at atmospheric pressure, so a 6 kg cylinder offers over 3,000 litres. Actual duration depends on flow rate, ambient temperature and whether gas is drawn from the vapour space, which is why we confirm your use pattern before recommending a size.
🏭 Where Compressed CO₂ Is Used
- ⚙️ Pneumatic tools — CO₂ drives air guns and portable devices where compressed air is unavailable;
- 🔬 Paintball and airsoft — safe supply and refilling of small cylinders for recreation venues;
- 🏥 Inflation and dispensing — CO₂ powers fire extinguishers, life jackets and carbonation units;
- 🚀 Laboratory pressurisation — pressure vessels and test rigs are charged with controlled CO₂.
💡 Why Choose REAL GAZ
- ✅ Pressure-rated hardware — valves and fittings are matched to CO₂ working pressure;
- 🧪 Weight transparency — net weight is marked so you can track consumption;
- 🎯 Frost awareness — guidance on regulator icing at high flow keeps equipment reliable;
- 🔒 Safe handling notes — every delivery includes clear instructions on pressure and temperature limits;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- check of working pressure and relief device condition;
- control of filling ratio to avoid overfilling;
- inspection for corrosion and damage;
- leak testing at the valve outlet and stem.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Pressure and Temperature
- Cylinder pressure follows temperature: at 0 °C it is roughly 35 bar, at 20 °C about 57 bar, and above 31 °C the liquid phase disappears at the critical point;
- Never leave cylinders in a closed car, near heaters or in direct summer sun, because a relief device may discharge;
- Open valves slowly, stand to the side of the outlet and check connections with approved leak detection fluid;
- Weigh the cylinder periodically against the tare weight stamped on the collar to know how much gas remains.
