Nitrox, or oxygen enriched air, is the gas of choice for recreational diving the world over. For dives up to 120 feet the benefits are clear - a reduction of both post-dive fatigue, and the risk of decompression sickness (the Bends).

Initially only available from land based gas mixing facilities, nitrox can now be generated from on-board systems for safer, healthier diving at any location.

With a Brownie’s NitroxMaker™, you simply dial-in your preferred mixture from 21% to 40% oxygen. The system automatically produces the desired gas and monitors the oxygen content with dual integrated digital oxygen analyzers. The use of two analyzers allows monitoring of both the membrane production and compressor output without dwell-time delays or input selection as well as a greater certainty of the final mix. The produced gas can be used to fill scuba tanks or can be stored in high-pressure “banks” for future use upon demand.

Other “partial pressure blending” systems produce nitrox by mixing pure oxygen with air to arrive at the desired nitrox mix. These PPB systems require the storage and handling of pure oxygen, which adds complexity and may carry classification society compliance issues. Blending procedures require calculations be performed prior to the mix, and then verification of the mix after the fact.

By contrast, the Brownie’s NitroxMaker™ system alleviates the burden of carrying and handling pure oxygen on the vessel. Operation is much less complicated and can be mastered with minimal training. And since the correct gas mixture is produced right from the system, there is less possibility of a faulty mix due to operator math errors.

NitroxMaker™ systems are reliable and relatively simple to use. Brownie’s will design and size a system to match your diving needs. Many existing high-pressure air compressor systems can be upgraded to a NitroxMaker™, giving you the benefits of diving nitrox while allowing you to retain your original compressor investment.

NitroxMaker™ cabinet, Refridgerated Dryer, Yacht Pro™ Compressor	4 Bank Fill Panel, Custom Tank Rack

Rotary Screw LP Compressor in Custom Garage	Membrane Cabinet NitroxMaker™ Control Panel (bottom left)

• Rotary Screw LP compressor - is precisely matched to the size of the high-pressure compressor. This compressor provides the drive gas that will flow through the NitroxMaker™ cabinet. This compressor can serve double duty by also providing ship’s air for other applications.
  
• Advanced Filtration and Refrigerated Dryer remove impurities and moisture to ensure only the highest quality air flows through the system.
  
• NitroxMaker™ cabinet - The operator designates the desired nitrox mix, the system does the rest. Clear air is converted into nitrox mixtures from 21% to 40%. Digital oxygen analyzers monitor the produced gas to ensure accuracy. Produced nitrox gas flows directly into the high-pressure compressor intake.
  
• High-pressure Compressor - Pumps supplied gas to pressures up to 5000 psi. For maximum versatility, the operator may select either gas produced from NitroxMaker™ or ambient air as the supply gas for the HP compressor.
  
• Control/Fill Panel - the traffic cop of the system. This panel controls the flow of gas from the hp compressor to the storage banks or to the fill whips. Precise controls allow for the “cascade filling” of tanks for the most efficient use of gas produced and stored.
  
• Storage Bottles/Banks - high capacity bottles for storing large volumes of gas. Banks can be set up to store a single or multiple gas mixtures simultaneously.

We design storage systems for air, oxygen, nitrox, helium or any other specialized gas needed on your vessel. Valves, regulators, plumbing and rack construction requirements are all taken into consideration at the earliest stages of the process. The result - a system integrated into your vessel. Storing large volumes of air, nitrox or other gas allows you to fill your scuba or firefighting scba tanks much quicker and more efficiently than filling directly from the compressor. For instance, filling 4 standard scuba tanks on our YP55 system would take approximately 52 minutes. By contrast, filling the same 4 cylinders from a cascade system would take less than 5 minutes - especially important for firefighting considerations.
