Drass Gas Mixer

Drass Gas Mixer is the first device of its kind capable to mix up to three given inlet gases so to obtain any required diving gas mixture. The machine creates custom gas mixtures (such as nitrox, heliox or trimix), with extremely high accuracy, and with high capacity (more than 250 Nm3/h).

 Uniquely on the market, the Drass Gas Mixer will accept as inlet gases non only pure gases (helium, nitrogen, oxygen) as the commercially available gas mixers, but also air or pre-mixed gases, such as heliox, nitrox, trimix.

This makes the Drass Gas Mixer capable to re-process residual mixed gas, after verification of their breathing quality, so to be used in next diving activities.

The capabilities include:

1. Oxygen enrichment, to add oxygen to pure gases or existing gas mixtures;
2. Heliox Dilution, to dilute the oxygen content of an existing gas mixture with helium background;
3. Nitrox Dilution, to dilute the oxygen content of an existing gas mixture with nitrogen background;
4. Printing of gas analysis results.

Above capabilities are obtained thanks to the high accuracy analysis system (O2+He) capable to measure the inlet gas mixtures, and the internally developed compensation algorithm, aimed to adjust the characteristics of the dosing system to fit any given inlet gas.

After a gas mixture has been produced, the system can analyse it with high accuracy (O2 error less than 0.1%), and print a sticker with the analysis results, together with the name of the operator and date/time, in plain text and with a QR code. Such sticker can then be applied to the bottle, for future reference.

 The unique capabilities of Drass Gas mixer assure great savings, by re-processing pre-mixed gases instead of purchasing new pure gases.
