ACTIVE FIRE PREVENTION WITH OXYREDUCT®
Maximum safety through preventative fire protection
Statistics show that a fire breaks out every two minutes in Germany, frequently causing serious damage. Whether warehouses, data centres or archives, every business needs absolutely reliable fire protection. Companies cannot afford downtime. So when fires occur, apart from protecting people, the most important priority is to maintain business processes.
Our portfolio includes the best fire protection solution to address this challenge: The VdS-approved OxyReduct® fire prevention system. Conventional fire protection systems are passive, meaning that they only react once a fire has broken out. The OxyReduct® preventative oxygen reduction system, on the other hand, actively ensures maximum safety even before fires start. This avoids consequential damage of the type that often occurs when extinguishing with water or other agents, such as foam.
OxyReduct® fire prevention system makes sure that fires cannot develop in the first place. By feeding a controlled supply of nitrogen into the protected area, it keeps oxygen concentration levels consistently below the ignition threshold of the combustible materials inside. The result: far less risk of open fire.

OxyReduct® VPSA

The OxyReduct® VPSA builds upon the well-known PSA technique of active, energy-efficient fire prevention. It is designed especially for use in protecting large rooms, as it can generate the large quantities of nitrogen they require in an environmentally friendly way. No wonder, then, that this fire protection system has become a standard solution in the warehousing industry.

OxyReduct® VPSA (Vacuum Pressure Swing Adsorption) generates the nitrogen required to reduce oxygen levels directly on site from the ambient air. It does this by separating gas mixtures using a physical method involving activated carbon. Compression and negative pressure are used to divide the ambient air into nitrogen and oxygen directly on site. Yet process pressure remains very low, so very little energy is required. The procedure can save up to 80% in operating and energy costs compared to conventional oxygen reduction systems.

VPSA stands for Vacuum Pressure Swing Adsorption
Adsorption process using Carbon Molecular Sieve (CMS)
Working pressure: around 1-2 bar (overpressure)
Advantages
The system’s modular design provides flexibility, and can even can be scaled for different performance classes.
It also allows several systems to be linked together, a major advantage for large storage areas due to the large quantities of nitrogen that can be produced.
The continuous stream of nitrogen makes the system suitable for protected areas with a high rate of air exchange.
OxyReduct® VPSA is an environmentally friendly technology suitable for continuous operation; it is also especially maintenance-friendly, since all of its components are easily accessible.
The system is VdS-approved, a testament to the high quality standards it meets.

OxyReduct® PSA

Sustainable protection through active fire prevention
OxyReduct® PSA systems are especially suitable for providing active fire prevention in large-volume rooms. The Pressure Swing Adsorption (PSA) method generates nitrogen using activated carbon.

PSA stands for Pressure Swing Adsorption
Adsorption process using Carbon Molecular Sieve (CMS)
Working pressure: around 6-8 bar (overpressure)

A compressor pressurises ambient air and pushes it through two containers containing Carbon Molecular Sieves (CMS for short), which separate nitrogen and oxygen molecules from one another. The oxygen binds to the activated carbon inside the containers, and is then directed outside as exhaust air. The nitrogen is fed into the protected area, where it distributes throughout the room at uniform concentration levels.
