Industrial He-N₂ Gas for sale — process-ready helium-nitrogen blends
Industrial He-N₂ Gas for sale from REAL GAZ covers inert blends of helium and nitrogen packed for workshop, plant and field conditions.
The gas is dry and oil-free, and the blend is selected to balance the cost of helium against the sensitivity the job requires.

REAL GAZ supplies this product according to EN ISO 14175 principles for inert shielding gases, ISO 10156 and EN ISO 11114-1 compatibility rules, suitable for factory and maintenance use.
🏭 Where Industrial He-N₂ Blends Are Used
- ⚙️ Pressure and leak testing — vessels, boilers and pipe systems are charged with a helium tracer blend and scanned for escape;
- 🔬 Inert purging — the blend displaces air from lines and chambers before sensitive processes begin;
- 🏥 Heat-exchanger inspection — tube bundles are checked for through-wall defects using sniffer detection;
- 🚀 Cooling and thermal tests — helium's high thermal conductivity helps in controlled-cooling and thermal trials.
💡 Why Choose REAL GAZ
- ✅ Industrial-grade packaging — cylinders and valves selected for workshop handling;
- 🧪 Blend flexibility — helium share is adjusted to the detector and the test pressure;
- 🎯 Cost-aware recipes — lower-helium blends keep consumption economical without losing detectability;
- 🔒 Non-flammable — no fire risk from the gas itself, although asphyxiation precautions still apply;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📦 Specifications and Supply
- Helium fractions chosen from low single digits up to higher levels;
- Nitrogen balance supplied at industrial or high purity grade;
- Cylinders typically 20 to 50 litres at up to 200 bar;
- Moisture level stated on request for dry-sensitive applications.
Because both gases are colourless and odourless, oxygen-deficient atmospheres can develop silently in poorly ventilated rooms. Use the gas only where ventilation is adequate and consider oxygen monitoring in enclosed spaces.
Helium sniffer testing works because helium atoms are very small and very light, so they escape through defects that water or air would never find. Mixing helium into nitrogen lets the operator work with a gas that is familiar and inexpensive while keeping the detection benefit. A modest tracer concentration, scanned with a calibrated sniffer, can reveal weld defects, loose flanges and faulty seals quickly. After testing, the blend can be vented safely in a ventilated area, because both components are naturally present in or harmless to the atmosphere, although large releases in enclosed rooms must still be avoided. For field work, secure the cylinder on a trolley, use a regulator with a suitable flow range and check every connection with leak-detection fluid before beginning the test so that the tracer is not wasted.
🔬 Quality Control & Safety
- multi-stage purification;
