Industrial Liquid Nitrogen — bulk and dewar nitrogen at −196 °C for process industries
Industrial Liquid Nitrogen from REAL GAZ is nitrogen cooled to −196 °C and delivered as a refrigerated liquid, giving plants a compact, high-capacity source of cold and inert gas.
One litre of liquid expands to about 694 litres of gas at ambient conditions, so a single dewar or bulk tank can replace dozens of high-pressure cylinders.

Vessels and transfer equipment follow EN 13458, ISO 21029 and EN 13530, and shipments are classified as UN 1977 under ADR for industrial consumers.
Supply options range from 50 to 230 litre pressurised dewars and 160 litre low-pressure dewars to cryogenic tanks of several thousand litres installed on your site with a vaporiser and telemetry. Purity is typically 99.99 % or better with oxygen below 10 ppm, and higher grades can be agreed for special processes. Plant managers should plan for evaporation losses in dewars, which are small but continuous, and size storage so that refills arrive before the level gets low.
🏭 Where Industrial Liquid Nitrogen Is Used
- ⚙️ Food freezing and chilling — cryogenic tunnels and mixers cool bakery, meat and ready-meal products quickly while preserving texture;
- 🔬 Shrink fitting and assembly — bearings, bushes and valve seats are chilled so they contract and slide into housings without force;
- 🏥 Pharmaceutical and chemical inerting — a nitrogen blanket removes oxygen and moisture from reactors, tanks and transfer lines;
- 🚀 Metal and rubber processing — cryogenic deflashing, cold treatment of tool steels and fine grinding of plastics all rely on liquid nitrogen.
💡 Why Choose REAL GAZ
- ✅ Large capacity, small footprint — a liquid tank stores far more nitrogen per square metre than any cylinder rack;
- 🧪 High purity — nitrogen is produced by air separation and drawn from the liquid phase with very low moisture;
- 🎯 Flexible supply — dewars, portable vessels and bulk tanks let you match the format to the process;
- 🔒 Controlled delivery — trained drivers, correct hoses and transfer procedures keep the filling operation safe;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- air separation and purity analysis of each production lot;
- vessel vacuum insulation and pressure relief checks;
- oxygen and dew point measurement on delivered product;
- visual inspection of couplings, hoses and dewar condition.
Operators should wear face shields, insulated gloves and closed footwear, and work only in ventilated areas fitted with oxygen-depletion monitors. Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
