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.

LaserPower
Nitrogen for 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:
- Paint saving
- Top quality treated surface & paint distribution
- Reduction of thrust pressure (by 40%)
- Top quality treated surface & paint distribution
