Oenology N2 Generators

Nitrogen for oenology

A shield against oxidation

Nitrogen is mostly used in winemaking to prevent wine oxidising, which is a cause of a deterioration of quality, involving changes in colour, aroma and flavour. In winemaking, the technique of inert wine storage tanks rapidly spread, in order to reduce the amount of oxygen in contact with the product, by injecting gaseous nitrogen.

The importance and advantage of having available on-site generated nitrogen

In cellars, the approach to the use of on-site produced nitrogen happened gradually, to satisfy the increasing demand from innovations with gas injection at bottling. World-wide there is rapid movement towards nitrogen generators replacing the traditional nitrogen production systems, such as bottles or liquid gas, due to the advantages derived from the convenience and cheapness of this system. The key of the success of the nitrogen generator is that by simply switching on the machine, all nitrogen needed can be produced on site, in complete safety, at the desired purity and definitely at lower cost compared to other supply systems.

Chemical and pharmaceutical industry, research and universities

Nitrogen at maximum purity

Isolcell boasts a twenty-year experience in the pharmaceutical and research sectors. We designed and built many  nitrogen production plants for universities and pharmaceutical industries all over the world  for the handling, storage and filtration of numerous chemical products, for the packaging of drugs and in research laboratories for analysis LS-MS (chromatography and mass spectrometry).

Main applications:

azoto per L'industria petrolchimica

Oil and gas industry

During the last twenty years Isolcell has built plants for the inertization of crude oil tanks, installations built inside refineries and on board oil tankers. Other systems are dedicated to the inertization and periodic cleaning of tanks and pipes.

Main applications:

azoto per l'industria elettronica

Electronic industry

From the adoption of lead-free alloys soldering processes have radically changed, new metal alloys in fact require a higher melting point than traditional soldering techniques, and this could undermine the soldering process itself.

Main applications:

Metal industry

(Heat treatment)

Isolcell nitrogen generators are the best solution for the metal industry to speed up producing processes, for heat treatments and explosion risks prevention.

Main applications:

Food industry

Modified atmosphere packaging

Worldwide, food products identified by brands of prestigious companies, use Isolcell nitrogen generators during their production and packaging processes.
Modified Atmosphere Packaging (MAP), is a packaging technology that, thanks to the replacement of air with a gas mixture, allows to increase the shelf life of food products (shelf life). Isolcell generators guarantee the quantity and quality necessary to maintain the organoleptic characteristics of their products.

Isolcell nitrogen generators comply with food contact.

In Europe, food nitrogen used as an additive is assigned an identification number: E941. Here you can download the E941 food nitrogen analysis sheet produced by PSA Isolcell nitrogen generators.

Main applications:

laser applications

High-pressure nitrogen cutting

Optic fibre technology effectively revolutionised the laser sector, leading nitrogen to become the main supporting gas in laser cutting processes.
Oxygen has therefore become less important and is now only used in laser cutting for extra-thick carbon steels and to cut copper.

Fibre laser technology has introduced on the market laser sources with truly high power levels (8-10-12 kW). They are now included in the catalogues of almost all manufacturers and 20 kW sources, which are currently being tested, are expected to be sold on the market in a few years.
Having high power means laser machines can cut at high pressure, i.e. using nitrogen, and reach incredible performance levels. These laser machines allow for truly high cutting speeds, in some cases even 7/8 higher than CO2 lasers, though this only applies to the high pressure nitrogen cutting process.

A complete revolution is therefore underway in the laser cutting sector. Except for the extra thicknesses of carbon steel, all other materials are processed by using nitrogen as a process gas. Where once carbon steel was cut using oxygen at pressure values from 0.5 to 2 bar, nowadays cutting is carried out with nitrogen from 8.5 to 18 bar. This means there is clearly the need to keep the cost of cutting gas provisioning under control.

By cutting carbon steel with nitrogen, you obtain a white cut and completely eliminate the light blue film on the cutting surface, which was a serious inconvenience at the welding and painting stage.

PSA Genion

Nitrogen generators for industrial painting

PSA technology

Isolcell has developed a technology that allows to save up to 40% of costs by replacing compressed air with nitrogen. GENION system has been tested by leading companies of the automotive industry, achieving excellent results:

The nitrogen produced by GENION with PSA technology (Pressure Swing Adsorption) is of extremely high purity and free of moisture and impurities. Excellent results are reached on all surfaces: plastic, glass, wood, metal, etc.

Our system is fully automatic and can be easily expanded in case of customization needs.
