Nitrox or EAN (enriched air Nitrox) is a widely accepted alternative to diving with air and offers various advantages. Trimix is a term referring to gas mixtures containing helium for deep diving.

DiveMix Ltd. offers three alternatives for Nitrox filling stations.

Partial pressure blending panels require a supply of medical grade oxygen and safely control the flow of oxygen together with oxygen compatible air (OCA) into an oxygen clean diving cylinder.

The panels have the advantage of low investment and zero energy consumption and are the ideal investment for Nitrox filling stations who have a reliable supply of oxygen with small or moderate filling requirements. The blending panels can also be used for mixing Trimix mixtures in diving cylinders. Partial pressure panels are also the only choice if blending gases with oxygen concentration higher than 40% is needed.

Premix / Continuous flow Nitrox systems utilize medical grade oxygen but the blending process is done at near ambient pressure in a mixing chamber. This solution offers more economic fills as most oxygen in the supply cylinders is used. After mixing the Nitrox is compressed with a suitable high pressure compressor providing quick fills.

Despite the higher investment and higher energy consumption, membrane Nitrox generators are the indispensable choice for filling stations where there is no reliable supply of oxygen or high volume of Nitrox is needed in relatively short time. This method of Nitrox generation and filling is ideal for large diving centers or Liveaboards where the membrane operation in conjunction with a suitable high pressure compressor is simple and quick
