Technical Gas LN₂ — technical-grade nitrogen in liquid form
Technical gas LN₂ is liquefied nitrogen of a grade intended for general industrial duties rather than for trace-sensitive analysis. REAL GAZ produces and distributes it for customers who value dependable quality at a sensible grade.
Once vaporised, one litre of liquid expands to roughly 690 litres of nitrogen gas, which makes LN₂ an efficient way to store and move large volumes.

Specifications are aligned with ISO 2503 for pressure regulators, EN 13458 for cryogenic tanks and ADR for transport, suitable for metalworking, packaging and electronics users.
A few practical notes support smooth operation. Technical nitrogen is normally supplied at purities of 99.5 to 99.99 per cent, which is enough for most cutting, packaging and heat-treatment work. Pipework should be sized for the vaporised flow, and a pressure-control station placed close to the consumer. Because nitrogen is an asphyxiant, oxygen monitors are recommended wherever vaporisers or vents are installed inside buildings. Regular analysis of oxygen content and dew point at the point of use is recommended, and our technicians can help you set up a simple monitoring routine that fits your production schedule.
🏭 Where LN₂ Is Used
- ⚙️ Laser cutting assist — vaporised nitrogen provides an oxidation-free cut edge on stainless steel and aluminium sheet;
- 🔬 Modified-atmosphere packaging — nitrogen flushes pouches and trays to extend shelf life of snacks, coffee and dried foods;
- 🏥 Heat treatment — furnaces use nitrogen-based atmospheres to prevent scaling and decarburisation of steel parts;
- 🚀 Electronics soldering — reflow and wave soldering lines run in nitrogen to improve wetting and reduce oxide on joints.
💡 Why Choose REAL GAZ
- ✅ Efficient storage — liquid form packs a very large gas volume into a small tank footprint, ideal for sites with limited space;
- 🧪 Stable technical grade — consistent purity suits processes where small oxygen traces are acceptable but swings are not;
- 🎯 Easy conversion to gas — a vaporiser and pressure-control station turn the liquid into line-pressure nitrogen on demand;
- 🔒 Cost-conscious service — delivery frequency and tank size are tuned to avoid over-ordering and unnecessary venting losses;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- routine purity and dew-point analysis;
- tanker and vessel cleaning verification;
- pressure-integrity checks on tanks and vaporisers;
- venting and ventilation guidance for enclosed rooms.
Cylinders and vessels comply with ADR / UN transport rules and relevant EN/ISO standards.
