Membrane Nitrogen Generators

Pneumatech’s PMNG range of membrane nitrogen generators utilize 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.

How does nitrogen generation work?

Atmospheric air contains essentially 78% nitrogen and 21% oxygen. Compressed air is passed through a technically advanced bundle of hollow membrane fibers. Nitrogen gas is separated from the feed air by selective permeation. Water vapor and oxygen rapidly permeate safely to the atmosphere while the nitrogen gas is discharged under pressure into the user’s nitrogen piping system, where it is ready to be used.

What differentiates the PMNG from other onsite nitrogen generators?

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. Only a supply of dry compressed air is needed to get nitrogen at the outlet of the generator. Also, the start-up procedure of the PMNG is made so straightforward that it does not require any specialist

PMNG 1-3

Pneumatech’s new smaller range of PMNG 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. The ease of installation and small flows, as well as achieving 99.5%, makes membrane generators ideal for industries such as breweries and small food manufacturers.

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. Only a supply of dry compressed air is needed to get nitrogen at the outlet of the generator. Also, the start-up procedure of the PMNG is made so straightforward that it does not require any specialist. Pneumatech offers a purity controller that delivers true consistent purity downstream in ANY flow situation.

Our simple design allows adjustments to be made easily, with a single screw. The purity is reliably monitored thanks to the optional battery-operated Nitrogen Analyser. The optional Economiser system is designed to save the utility costs of operating the compressor and reduces the wear and tear on Air and Nitrogen Systems. This cost-effective solution from Pneumatech significantly reduces nitrogen costs over traditional sources of nitrogen supply.

PMNG 5-75 S

Pneumatech’s PMNG nitrogen generators utilize proprietary membrane separation technology. Membrane generators are an excellent choice in low (95%) 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.

With the PMNG, on-site nitrogen supply becomes exceptionally convenient. All pre-filters and controls are included inside the canopy. Only a supply of dry compressed air and electricity is needed to get nitrogen at the outlet of the generator. An outlet buffer vessel is not required, which results in significant space savings and easy installation. Also, the start-up procedure of the PMNG is made so straightforward that it does not require any specialist.

Thanks to the PurelogicTM controller, the PMNG offers impressive control and monitoring capabilities. Various pressure and temperature sensors ensure that the membranes are used in the right working conditions. The nitrogen purity can easily be set with the purity regulator and is reliably monitored. The optional pressure dew point (PDP) sensor and oil indicator sensor safeguard air purity of class 1:4:1 according to ISO8573- 1:2010 at the inlet of the membranes.

Benefits:

• Guaranteed nitrogen purity
  – Reliable purity measurement
  – Easy to set up the device for purity levels between 95% and 99.5%
• Energy-saving control
• Proprietary membrane technology ensuring lasting performance
  – No ageing
  – No heater
• All-in-one plug & play solution
  – All filters integrated in enclosed canopy design
  – No buffer vessels required
  – Instant supply of nitrogen
  – No specialist installation or commissioning
• Optimal control and monitoring thanks to Purelogic ™ controller
