High Pressure He-N₂ Gas Cylinder — higher fill pressure, more usable gas
A High Pressure He-N₂ Gas Cylinder from REAL GAZ stores more gas in the same footprint, which means fewer changeovers and less handling.
Higher pressure also places greater demands on the cylinder wall, valve and regulator, so every component must be correctly rated.

REAL GAZ supplies this product according to ISO 9809-1 for quenched and tempered steel, ISO 9809-3, EN ISO 10297 and TPED certification, suitable for high-consumption and space-constrained users.
🏭 Where High Pressure He-N₂ Cylinders Are Used
- ⚙️ Large leak-test stations — extended runs without cylinder change;
- 🔬 High-pressure test benches — systems that need blend delivered at elevated supply pressure;
- 🏥 Remote sites — fewer cylinders to transport to locations with difficult access;
- 🚀 Test-rig charging — rapid filling of vessels with a helium-nitrogen mixture.
💡 Why Choose REAL GAZ
- ✅ More gas per cylinder — higher fill pressure raises usable volume;
- 🧪 Careful filling — helium is added slowly to manage heat of compression;
- 🎯 Rated components — valves and regulators matched to the pressure class;
- 🔒 Integrity checks — each cylinder is leak-tested after filling;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Specifications and Supply
- Rated fill pressures of 200 and 300 bar subject to cylinder;
- Pressure-rated valves and outlet connections;
- Burst-disc and valve guard options;
- Regulators rated for the full inlet pressure.
Always use a regulator designed for the cylinder's full pressure, open the valve slowly and keep the cylinder away from heat. Pressure rises with temperature, so never leave a cylinder in direct sun.
Filling to higher pressure requires patience. Gas heats as it is compressed, so the cylinder is filled gradually and allowed to settle before the final pressure is recorded. Helium behaves differently from nitrogen under compression, which is one reason we verify the final composition by analysis instead of relying on pressure alone. Cylinders are inspected for the relevant test stamp, and valves are checked for smooth operation and leak tightness. Because pressure ratings vary with cylinder design and regional rules, always confirm the working pressure of the cylinder and the rated inlet of your regulator before connecting. Transport of cylinders at higher pressure follows the same ADR framework, with cylinders secured upright, valves protected and the load documented, so that handling on both vehicles and sites remains routine and safe.
🔬 Quality Control & Safety
- inspection of cylinder test dates and markings;
- controlled filling sequence to avoid stratification;
- verification of composition before release;
- pressure and leak checks of valve and connections.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
