Introduction
The Goals of the installation
Fires can cause very great damage to the environment and to property. In addition, there is a high potential risk to humans.
The primary goal of the LOX system is to prevent fire in a specific area or to drastically reduce the risk of fire. A fire that does
start, despite of the precautions, will remain limited and will develop less quickly. This significantly increases the escape time
of those present and the intervention time for the emergency services.
The LOX system works on the basis of permanent oxygen reduction by supplementing additional nitrogen. The air around us
consists of approximately 20.8% oxygen, 78% nitrogen and 1% other gases. The LOX H.P. LOW OXYGEN system changes the
balance between oxygen and nitrogen. The optimum oxygen percentage depends on the nature of the flammable substances.
In the LOX system, a nitrogen generator is used. In this generator compressed air is separated into oxygen and nitrogen. The
oxygen is relieved into the surrounding area. The nitrogen is used to regulate the mixture of oxygen and nitrogen in the
protected room. The required compressed air is produced by means of a compressor.
Only FX Prevent or an authorized party is allowed to modify the installation. The installation should only be used for the
purpose for which it was designed. The system is designed and tuned for specific operating parameters. These may only be
changed by FX Prevent or its authorized party. The operating pressure of the installation is between 0 and 8 bar. The design
pressure is 10 bar. This pressure may not be exceeded under any circumstances. The temperature of the room where the
system is installed should be no lower than +3 °C and no higher than +40 °C.
Redundancy
The LOX system, like all other technical installations, has the risk of malfunctioning. When this happens, the prevention of fire
in a specific area can no longer be guaranteed. In order to still be able to give this guarantee, the concept of
redundancy
is
very important in the design of the LOW OXYGEN systems. FX-Prevent follows the Master/Slave principle for this.
A master version of the LOX system controls a complete single system. This can consist of a compressed air production
system, nitrogen generator system, sensors and a measurement and control module. The capacity is calculated in such a way
that the installation can independently control the percentage of the protected area.
A slave version of the LOX system controls a complete or partially complete installation. This can consist of a compressed air
production system, nitrogen generator system, sensors and a measurement and control module. The machine is designed in
such a way that it can independently maintain the percentage in the protected area if there is a problem in the master
system.
The composition of the Master and Slave system and the level of redundancy are tailored to the user's requirements and can
therefore be different for each installation.
