Bulk & Cryogenic Helium Gas Solutions for High-Tech Industries

Ultra-Pure Helium for Cryogenics, Leak Detection, Welding & Specialty Applications

Helium (He), is a colourless, odourless inert noble gas celebrated for its extraordinarily low boiling point of −268.9 °C and minimal molecular weight. Commercially, it is produced by fractional distillation of natural gas streams containing between 0.3 % and 7 % helium—sourced predominantly from the United States, Qatar and Algeria.

In healthcare, liquid helium is critical for cooling superconducting magnets in MRI and NMR spectroscopy systems, ensuring stable magnetic fields and high-resolution imaging. Research laboratories rely on helium as a carrier gas in gas chromatography and as a purge medium in mass spectrometers, where its inertness prevents sample contamination. High-energy physics installations—such as particle accelerators—exploit helium’s cryogenic properties to maintain superconductivity in their magnets.

Helium’s low density and non-flammability make it ideal as a lifting gas for weather balloons, environmental monitoring payloads and high-altitude research platforms. In welding and metal fabrication, helium–argon blends shield aluminium and magnesium arcs, improving heat transfer and weld quality. Telecommunications manufacturers also use helium to cool fibre-optic cable manufacturing ovens, reducing micro-cracks and enhancing signal integrity.

Although helium is non-reactive, it can displace oxygen in confined spaces, posing a suffocation risk if ventilation is inadequate. Proper oxygen-monitoring sensors and cylinder restraints are essential. Handling liquid helium requires cryogenic personal protective equipment—insulated gloves, face shields and vacuum-jacketed dewars—to prevent frostbite and cold burns.

NovaAir delivers turnkey helium services tailored to each sector’s exacting standards. We supply ultra-high-purity helium (99.999 %+) in ISO tanks, tube trailers and seamless cylinders, and offer automated liquid dewar refilling systems with real-time level monitoring for uninterrupted cryogenic operations. Custom on-site mixing stations produce heliox and other breathing mixtures for diving and respiratory therapy. Comprehensive regulatory compliance audits, OSHA/NFPA-aligned protocols and hands-on operator training round out our service, all underpinned by smart telemetry and predictive resupply algorithms.

With its unique physical properties and broad industry applications, helium remains a strategic resource across high-tech, medical and research fields. NovaAir’s end-to-end supply chain, bespoke gas solutions and safety expertise empower customers to harness helium’s full potential without compromise.
