Specialty Gas for Diving — analysed oxygen, helium and nitrogen blends for technical and commercial divers
Specialty gas for diving has no room for guesswork, because the mix decides how deep and how long a dive can safely go. REAL GAZ supplies nitrox, trimix and heliox blends prepared from high purity oxygen, helium and nitrogen, with every cylinder analysed and labelled for maximum operating depth.
Oxygen compatible cylinders and valves are cleaned and handled separately to keep hydrocarbons out of the breathing gas path.

Gas quality is aligned with EN 12021 for breathing air and compressed gases, and cylinders are handled in line with ISO 9809 and EN 144 valve practice for technical diving and offshore work.
🏭 Where Diving Gases Are Used
- 🤿 Technical diving — trimix blends reduce narcosis and oxygen toxicity risk on deep wreck and cave dives;
- 🛢️ Commercial and offshore diving — heliox supports long bottom times in saturation and surface-supplied operations;
- 🎓 Training centres — nitrox in standard blends lets instructors teach enriched air courses with consistent supply;
- 🌊 Underwater inspection teams — survey crews on pipelines, dams and ports rely on predictable bottom mixes for repeated dives;
💡 Why Choose REAL GAZ
- ✅ Analysed before release — oxygen and helium fractions are measured and written on the cylinder tag;
- 🧪 Oxygen-clean preparation — cylinders, valves and fittings are cleaned for enriched oxygen service;
- 🎯 Blends for your plan — tell us the depth profile and we will propose a mix and fill pressure;
- 🔒 Clear identification — colour coding and labels meet national practice, avoiding mix-ups on the boat;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- oxygen cleaning and inspection of valves;
- helium and oxygen analysis with calibrated analysers;
- carbon monoxide and moisture screening;
- pressure test, thread check and leak inspection.
Cylinders carry valid test dates and are shipped per ADR / UN rules, with oxidising gas marking where required.
⚠️ Dive Gas Handling Notes
Always analyse a cylinder yourself before breathing from it, label it with the measured oxygen and helium fractions, and record the maximum operating depth. Oxygen above 23.5% requires oxygen-clean equipment, and high pressure oxygen must be released slowly to prevent heat of compression. Store cylinders upright and secured, out of direct sun, and never fill them with unknown compressors or contaminated hoses. Our team can explain blending methods, analyser calibration and fill logging for your centre, but dive planning, decompression schedules and personnel training remain the work of certified instructors and diving supervisors.
⚙️ Trusted Gas Solutions
REAL GAZ provides specialty gas for diving to dive centres, port authorities, offshore contractors and rescue units in Azerbaijan, Turkey, Georgia, Uzbekistan and the USA. We never advise on dive planning itself, but we make sure the gas in your cylinder matches the number on its label.
REAL GAZ — what is on the label is what you breathe.
