Pneumatech PMNG2
Nitrogen Gas Generator

Pneumatech PMNG2 - Pneumatic Membrane Nitrogen Generator

Pneumatech PMNG2 is a membrane nitrogen generator belonging to Pneumatech's new range of small PMNG nitrogen generators. With membrane separation technology, these Pneumatech Nitrogen generators are an excellent choice in applications with high - medium - low purity percentage (99.5% - 90%) .

Without the need for an additional booster , Pneumatech PMNG2 can reach a pressure of 13 bar.

To have nitrogen available at the generator output, simply connect it to a compressor with dryer . Furthermore, the PMNG start -up procedure is so intuitive that it does not require the intervention of specialized personnel .

Functional specifications

How a nitrogen generator with membrane technology works

As an alternative to the installation of a cryogenic system, it is possible to generate nitrogen by means of a special PSA or membrane generator. In particular, the membrane technology consists of a main module with a diameter of 10 cm and hollow polymer fibers . Clean, dry compressed air is introduced here by means of a permeation process , whereby water, oxygen and part of the argon escape through the side of the fibers facing the membrane. Nitrogen therefore remains isolated, due to its slower permeation , with respect to oxygen and carbon dioxide. To avoid overpressure , there is a vent where faster exhaust gases can escape, leaving pure nitrogen.

In more powerful nitrogen generators such as the Pneumatech PMNG2 , the filters and dryer are already installed inside.

Use of nitrogen generator

Being an inert gas (not very reactive), nitrogen has various types of uses in the agro-food sector. Nitrogen is in fact used as a shielding gas in inerting processes. Here are some examples of use.

Preservation of food products

In the food sector, the introduction of gaseous nitrogen serves to preserve food products from contact with oxygen and humidity contained in the air . The packaging of food using the MAP ( Modified Atmosphere Packacking) process involves the packaging of food in an atmosphere protected by nitrogen, thus avoiding contact with oxygen and extending the shelf life of the food.

Nitrogen for the wine sector: wine bottling and tank cleaning

This inert gas prevents oxidation of wine and preserves its taste , color and properties . Normally, nitrogen finds its application in the cleaning of tanks and in the bottling of wine .

Agricultural sector use

Nitrogen fertilization of cultures promotes plant growth . This gas is in fact an important nutrient, transformed by plants into proteins .

Use of nitrogen in the industrial sector

Nitrogen is used in various industrial sectors to prevent fires and explosions . It is piped into tanks , pipes , reactors or mines to reduce the natural oxygen content of the air. In fact, oxygen reacting with different types of gas and dust can cause combustion.

Nitrogen for brazing and laser cutting

The nitrogen generated by PMNG 2 can be used in various procedures such as brazing , arc welding and laser cutting as cutting gas, combustible gas, shielding gas and inert gas . Eliminates residual oxygen thus avoiding oxidation of components.
