Liquid Oxygen Cylinder — insulated cylinders for controlled withdrawal of oxygen
A liquid oxygen cylinder is a vacuum-insulated vessel that holds oxygen at cryogenic temperature and delivers it as gas through an internal or external vaporiser. REAL GAZ offers these cylinders where a full bulk tank would be too large.
Compared with a conventional high-pressure steel cylinder, a liquid cylinder holds many times more oxygen by volume, so changeovers are far less frequent.
Compared with a conventional high-pressure steel cylinder, a liquid cylinder holds many times more oxygen by volume, so changeovers are far less frequent.
Vessels follow ISO 21029, EN 1251, TPED, ISO 11114 material compatibility and ADR, suitable for welding shops, aquaculture and laboratory users.
Small-volume oxygen users often prefer a liquid cylinder to a pack of steel cylinders. A single 180 litre vessel holds the gas equivalent of roughly twenty standard high-pressure cylinders, and delivery usually takes place at a controlled pressure of around 10 to 16 bar. We recommend a trained operator, a designated storage position outdoors or in a well-ventilated area, and a clear marking of the vessel with oxygen hazard signs. Customers who operate seasonally, such as fish farms, can arrange short-term supply during the busy months and return the vessels afterwards without long contracts.
🏭 Where Liquid Oxygen Cylinders Is Used
- ⚙️ Fish farming — oxygen is dissolved into pond and tank water to keep stocking densities healthy in aquaculture units;
- 🔬 Workshop supply — a single liquid cylinder feeds a manifold for cutting and heating stations through a pressure regulator;
- 🏥 Laboratory furnaces — combustion analysis and high-temperature oxidation tests use steady oxygen from a vaporising cylinder;
- 🚀 Remote sites — construction camps and mining operations without bulk infrastructure use cylinders for cutting and repair work.
💡 Why Choose REAL GAZ
- ✅ Fewer changeovers — large oxygen content per cylinder means longer intervals between exchanges;
- 🧪 Compact delivery — castor-mounted cylinders are positioned near the point of use and connected with short pipework;
- 🎯 Controlled withdrawal — pressure-building circuits and economiser valves keep flow smooth and limit venting losses;
- 🔒 Exchange and service — our team collects empties, delivers full cylinders and inspects valves on each visit;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- vacuum and relief-valve inspection;
- oxygen-cleanliness verification of valves and fittings;
- purity analysis of filled oxygen;
- securing and transport checks in line with ADR.
Cylinders and vessels comply with ADR / UN transport rules and relevant EN/ISO standards.
