Technical Gas Liquid Nitrogen — technical-grade LN₂ for inerting, purging and cooling
Technical Gas Liquid Nitrogen from REAL GAZ is a general-purpose grade of liquid nitrogen aimed at contractors and plant operators who need a robust, economical source of inert gas and low-temperature cooling.
It is delivered as liquid and either used cold or vaporised into a gas stream at the required flow and pressure.
It is delivered as liquid and either used cold or vaporised into a gas stream at the required flow and pressure.
Transport and storage conform to ADR class 2, vessel standards EN 13458 and EN 1251, with gas specifications set for technical and construction applications.
Vaporiser trailers can convert liquid into high-pressure gas at the work site, allowing pipelines, tanks and heat exchangers to be purged or pressure-tested without a bank of cylinders. A typical tanker load supplies several thousand cubic metres of gas, and flow rates can be adjusted from a trickle to hundreds of cubic metres an hour. Technical grade is not intended for food, medical or analytical use, for which a higher grade should be ordered and documented.
🏭 Where Technical Liquid Nitrogen Is Used
- ⚙️ Pipeline and vessel purging — nitrogen displaces air and flammable vapours before welding, cleaning or maintenance entry;
- 🔬 Pressure and tightness testing — vaporised nitrogen provides a safe, non-reactive test medium for pipelines and process equipment;
- 🏥 Pipeline drying — dry nitrogen sweeps moisture from lines after hydrotesting, preventing corrosion and ice formation;
- 🚀 Cold fitting and freezing — liquid nitrogen freezes pipe sections for repair work without draining the system and chills parts for interference fits.
💡 Why Choose REAL GAZ
- ✅ Economical bulk gas — liquid delivery lowers the cost per cubic metre against cylinder supply for large jobs;
- 🧪 Inert and dry — nitrogen prevents oxidation, fire and moisture damage in sensitive work;
- 🎯 Site support — vaporisers, hoses and regulators can be provided alongside the liquid;
- 🔒 Safe handling guidance — toolbox talks and written procedures cover cold hazards and confined spaces;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- production from air separation with purity records;
- pressure relief and safety valve verification;
- moisture checks on vaporised gas;
- tanker and hose integrity inspection before offloading.
Never trap liquid nitrogen in a closed pipe without relief protection, and always supply ventilation or breathing apparatus when entering vessels that have been purged. Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
