In aerospace, life support systems, particularly oxygen support, are critical for human survival in the harsh environments of space and high-altitude flight. these systems ensure a breathable atmosphere, providing oxygen generation, regulation, and monitoring, along with other life-sustaining functions.

Rocket propellant is what causes the spacecraft to be thrusted upward. the engines that are used in spacecraft create a thrust by utilizing a chemical reaction between hydrogen and oxygen, form very hot gases that expand and ejectedat very high speeds through the end nozzle at the bottom of the craft, and propel the rocker into space.

In aerospace manufacturing and repair, welding and cutting demand exceptional purity and precision. KELVINS supply high-purity argon (Ar), helium (He), hydrogen (H₂), and nitrogen (N₂) for TIG welding, MIG welding, plasma arc cutting, and laser cutting. Our equipment portfolio includes precision gas mixers, electronic flow controllers, high-accuracy pressure regulators, gas distribution manifolds. Whether for engine component fabrication, airframe assembly, or repair depot operations, our solutions help achieve clean, defect-free, high-strength welds that meet rigorous aerospace standards (e.g., NADCAP, AWS D17.1).

In the aerospace industry, leak detection is critical for safety and performance. KELVINS can supply high-purity helium (He), hydrogen-nitrogen blends (5% H₂ in N₂), and other tracer gases for a wide range of leak testing applications — including fuel system integrity checks, welded joint verification, pressure vessel testing, vacuum chamber validation, and environmental control system (ECS) sealing. Whether for component manufacturing, assembly line testing, or maintenance and overhaul (MRO) operations, our solutions help identify micro-leaks with high sensitivity and repeatability, ensuring compliance with stringent industry standards such as ASTM E499, ASME B31.3, and customer-specific aerospace specifications.

In aerospace, leak detection ensures safety and reliability. We supply high-purity helium and hydrogen-nitrogen blends for testing fuel tanks, propulsion systems, environmental control systems (ECS), and vacuum chambers. Equipment includes helium mass spectrometer leak detectors, sniffer probes, pressure decay testers, vacuum gauges, and calibrated leak standards. Our solutions help identify micro-leaks with high sensitivity, supporting component manufacturing, assembly verification, and MRO operations.
