Nitrogen generators for the wine industry: Enhancing quality and efficiency

In the world of winemaking, the pursuit of excellence and the preservation of quality are paramount. Therefore, winemakers are turning to a game-changing solution to enhance their craft: nitrogen gas. From preventing oxidation to controlling carbonation, nitrogen plays a vital role throughout the winemaking process. 

How nitrogen is used through the process

Nitrogen is employed at various stages of the wine making process:

Membrane Nitrogen Gas Generators

Pneumatech’s PMNG range of nitrogen generators utilizes proprietary membrane separation technology. Membrane generators are an excellent choice in low (90%) to medium (99,5%) purity applications such as tire inflation, fire prevention, tank blanketing and pipeline drying. Nitrogen pressures can go up to 12 bar (g) without the need for an additional booster.

Engineered for simplicity, durability and ease of use make the PMNG what we believe to be the most user friendly unit in the market. All pre-filters and controls are included inside the canopy.

PSA Nitrogen Gas Generators

The PPNG series is Pneumatech’s premium on-site nitrogen solution for low to high flows, with best-in-class performance and the most complete scope of supply.

The generator has outstanding air factors at full load thanks to the use of highly efficient Carbon Molecular Sieves (CMS) and back-flow pressurization.
The air consumption is also optimized at reduced nitrogen flow or pressure demands, thanks to the advanced energy saving algorithm, which automatically adjusts the cycle times of the generator.
The control and monitoring capabilities of the PPNG series are truly impressive.

PSA Oxygen Generators

Pneumatech gives oxygen to your business. With the PPOG series, Pneumatech offers an attractive replacement for traditional oxygen supply with very interesting returns on investment.

The PPOG1-120 series uses Pressure Swing Adsorption technology to extract oxygen from compressed air, resulting in oxygen purity levels up to 95%.

The PPOG 2-18 HE series is a true game changer in on-site oxygen generation. 30% more efficient than traditional oxygen generators, the PPOG HE gives you the oxygen volume, purity and reliability you need at a massively reduced cost and a smaller environmental footprint.
