Nitrox systems are used by dive operations to produce enriched air nitrox by increasing the oxygen content of breathing gas. They are designed to support safe, consistent nitrox production as part of daily diving operations.
NRC International is a global leader in nitrox systems and a pioneer in modern nitrox diving. Since 2000, it has shaped the industry with initiatives like the widely adopted 'Nitrox for Free' program and training standards still used today. For over two decades, leading dive centers around the world have relied on NRC’s professional-grade technology. It is engineered for exceptional reliability, regardless of the production method.
Best suited for high-volume nitrox production, membrane systems generate nitrox from ambient air by separating nitrogen before compression. This method avoids the handling of pure oxygen and is widely used by dive centers that require continuous, large-scale nitrox production
Best suited for centers with a reliable oxygen supply, continuous blending enriches compressed air using pure oxygen upstream of the compressor. This method enables higher nitrox output but requires controlled oxygen handling, trained personnel, and a consistent supply of 100% oxygen
Best suited for small volumes or high oxygen percentages, partial pressure blending adds pure oxygen directly into the cylinder before filling with air. This method is appropriate for low-volume production or gas mixes requiring high oxygen percentages, provided proper oxygen handling procedures are in place.
*Please be aware that while other techniques exist, they are not endorsed by NRC International. Safety and reliability remain our top priorities.
This video explains how a membrane-based nitrox system produces enriched air nitrox by separating nitrogen from ambient air in a dive center environment.
