HIGH PRESSURE LOX — liquid oxygen converted to high-pressure gas
High pressure LOX describes liquid oxygen that is pumped and vaporised to deliver oxygen gas at elevated pressure, often 200 to 300 bar. REAL GAZ uses cryogenic pump technology, which is more energy-efficient than gas compression and keeps the product free of lubricant contamination.
The result is high-pressure oxygen of consistent purity, ready for cylinder filling or direct use.
The result is high-pressure oxygen of consistent purity, ready for cylinder filling or direct use.
Systems are designed with reference to ISO 10286, EN ISO 11114 and ISO 15001 for oxygen service, and cylinders to ISO 9809, for industrial duty.
🏭 Where High-Pressure LOX Are Used
- 🛢️ Cylinder and bundle filling — pumped LOX fills oxygen cylinders and bundles to full working pressure quickly and cleanly;
- 🏭 Pressurised process feeds — high-pressure lines supply reactors and furnaces that run above atmospheric pressure;
- 🔧 Hydrostatic and pressure testing — oxygen-compatible high-pressure supply supports component qualification;
- 🚒 Emergency and standby systems — manifolds hold pressurised oxygen reserves for critical equipment.
💡 Why Choose REAL GAZ
- ✅ Oil-free pressurisation — cryogenic pumps avoid the oil carryover that compressors can introduce;
- 🧪 Controlled quality — purity is verified after vaporisation, before gas enters the cylinder;
- 🎯 Pressure options — fill pressures are matched to cylinder rating and application;
- 🔒 Oxygen-rated components — valves, regulators and manifolds are cleaned and selected for high-pressure oxygen;
- 📄 Certificate of Analysis (CoA) — supplied with each filling to confirm purity and fill pressure.
🔬 Quality Control & Safety
- cryogenic pump maintenance and oxygen cleaning;
- post-vaporisation purity and moisture analysis;
- pressure-relief device and burst-disc verification;
- leak testing at working pressure.
High-pressure oxygen is hazardous around grease and rapid valve opening; cylinders ship under ADR / UN 1072 with correct pressure markings.
📦 Practical Notes on High-Pressure LOX
A cryogenic pump compresses the liquid, not the gas, so the work required is a fraction of gas compression and heat is removed by the vaporiser. After vaporisation, oxygen passes through a high-pressure manifold with check valves and filters to the filling ramp. Components must be degreased to oxygen standards and made of compatible alloys such as brass, copper and Monel, with ignition-resistant seals. Fill slowly to keep temperatures down, since rapid pressurisation can cause adiabatic heating inside valves and cylinders.
