The nytrogen N2 generator or oxygen reducer, can be quickly applied to the cold rooms that are prearranged in controlled atmosphere, decreasing the percentage of O2 from 21 vol.% to less than 3 vol.%.

The propane or butane gas coming from special containers is conveyed towards a proportional volumetric batching plant, that blends it with air.

The resulting mixture will be transferred into a combustion chamber where it will be burned. The produced gas that will arrive from it after it has been cooled with running water, will be pushed through special pipes into the room. The introduced mixture contains 86% N2, a 13% of CO2 and not more than 1% of O2.

This will cause a constant washing and an outflow of the air from the room by means of a special valve.

Consequently a progressive impoverishment of the oxygen value contained in the room will take place. The machine is able to mantain the characteristics of the mixture produced independently from the variation of pressure and of the flow rate of gas and air.

The electric equipment that controls it, is provided with all the required safety systems for gas systems and with equipment blocking systems to prevent any kind of failure; lack of gas; lack of cooling water; faults of combustion and backfire.

ADVANTAGES

Quick decrease of oxygen percentage wihin the room after it has been shut.
High percentage of introduced steam, being the steam produced during the combustion.
Irrelevant unburnt gas residuals, amount to less than 0,001%.
