Technical Gas Liquid Cylinders for Oxygen, Nitrogen, Helium — three cryogenic liquids, one dependable supplier
Plants that use several cryogens benefit from technical gas liquid cylinders for oxygen, nitrogen, helium sourced from one place. REAL GAZ fills dedicated vessels for each gas: liquid oxygen at −183 °C, liquid nitrogen at −196 °C and liquid helium at −269 °C.
Each product has its own vessel design, valve set and cleaning level, so safety and purity are never compromised.
Each product has its own vessel design, valve set and cleaning level, so safety and purity are never compromised.
Oxygen vessels are cleaned per EN 12300, medical-grade oxygen follows EN ISO 7396-1 supply rules, and vessels conform to EN 1251 and ISO 21029-1.
🏭 Where Oxygen, Nitrogen and Helium Liquid Cylinders Are Used
- ⚙️ Oxygen for steel and glass — liquid oxygen enriches furnace combustion and supports cutting and melting operations;
- 🔬 Nitrogen for inerting — liquid nitrogen provides blanketing for tanks, chemical reactors and food packaging lines;
- 🏥 Helium for leak testing — liquid helium and its boil-off gas serve mass-spectrometer leak detection and cryogenic research;
- 🚀 Mixed-gas laboratories — one delivery round replenishes all three cryogens for multi-purpose research facilities.
💡 Why Choose REAL GAZ
- ✅ Gas-specific vessels — oxygen, nitrogen and helium never share a vessel, avoiding cross-contamination;
- 🧪 Correct relief settings — each product has a vessel with relief and burst devices matched to its properties;
- 🎯 Helium conservation advice — we recommend transfer and recovery methods that limit costly helium loss;
- 🔒 Clear identification — body colour, labels and valve threads differ by gas to prevent connection errors.
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Handling & Storage of Oxygen, Nitrogen and Helium Liquid Cylinders
- Keep oxygen vessels clear of grease, oil and flammable liquids.
- Ventilate rooms for nitrogen and helium, since both can displace breathable air.
- Use helium transfer lines with full vacuum insulation.
- Remember that helium has a very small latent heat, so even minor heat leaks cause noticeable losses and transfer lines should be insulated.
- Never connect an oxygen vessel to equipment that has been used with oil or grease unless it has been cleaned and inspected.
- For nitrogen, install an oxygen-deficiency monitor in rooms where vessels vent or are filled.
- Plan separate storage zones for each cryogen, with clear signage to prevent mix-ups during exchange.
🔬 Quality Control & Safety
- oxygen-compatibility cleaning checks;
- helium purity and air-ingress analysis;
- nitrogen moisture verification;
- vacuum, valve and relief inspection for each vessel.
Transport complies with ADR / UN, and vessels bear the markings required for each cryogenic gas.
