Oxeo EcoPrevent VG

Open fires will not emerge in the first place

Advantages

The Oxeo EcoPrevent VG reduces the oxygen content in the air by the controlled supply of nitrogen to the protected area in order to create a "fire-proof" atmosphere and maintains this level permanently. This prevents the outbreak of an open fire. Oxeo EcoPrevent PG generates the nitrogen used to reduce the oxygen on site by means of a nitrogen generator. The protected areas can still be entered by unimpaired individuals.

Prevents fire from occurring
Damage is limited to the defective component
Ensures availability of technical equipment and processes
No smoke-related damage
The Oxeo EcoPrevent PG system avoids the possible side-effects of normal fire extinguishing methods: rapid temperature changes in specific spots, electric short-circuits, extinguishing agent residue

The VPSA nitrogen generating system works on the pressure change principle. Containers filled with carbon granulate separate the oxygen and thus reduce the oxygen content in the air. The granulate consists of specially treated active carbon which enables the separation of oxygen and nitrogen.
The compressed ambient air enters an adsorption tank via an energy-efficient low-pressure compressor. The tank contains the carbon granulate which retains the smaller oxygen molecules from the air in its pores. The nitrogen can thus flow past and is thereby separated from the oxygen. One cycle lasts approx. 60 seconds and includes the nitrogen separation in a tank (adsorption) and the removal by vacuum pump of the bound oxygen in a second tank (resorption). As this process is continuously, alternately repeating itself, nitrogen is permanently available for introduction into the protected area.
