Operating principles oxygen reduction fire prevention systems

6 April 2021

The benefits of preventing fire, rather than extinguishing it, make oxygen reduction systems well suited for applications where fire can cause irreplaceable damage and where traditional fire suppression systems are unacceptable or inappropriate.

Hypoxic air technology for fire prevention, also known as an oxygen reduction system (Presscon FX Prevent systems, LOX Low Oxygen Systems), is a proactive fire protection technology based on a permanent reduction of the oxygen level in the protected areas. The technology of reducing oxygen by administering nitrogen has been used for decades in various industries.

We have more than 20 years of experience with various methods of controlling the oxygen and nitrogen concentrations in the air, using nitrogen generators. The agriculture and horticulture industry uses the principles of this technology to preserve goods. The petrochemical industry uses it to create a nitrogen blanket on combustible materials (blanketing). In this capacity, this technology has proven to be very successful and reliable. The most popular methods in this industry use a membrane filter or a (V)PSA filter, which stands for "(Vacuum) Pressure Swing Adsorption".

High Performance PSA (HP-PSA)

With the use of PSA (Pressure Swing Adsorption) technology, Presscon FX Prevent has developed a completely new (HP - High Performance) system that eliminates the disadvantages experienced with a traditional PSA system. The HP technology distinguishes itself by an optimized air flow in the system and a unique pressure system for the activated carbon. These improvements create a system that is environmentally friendly, with significantly longer life and lower energy consumption. Our patented compression tubes require less than 2 m3 of compressed air to produce 1 m3 of 95% pure nitrogen. In addition to lower energy consumption, this also means that when using a LOX system, a lower capacity compressor can be used to achieve the desired compressed air volume.

Compared to traditional PSA technology, the HP-PSA offers significant energy savings. When compared to a diaphragm system, energy savings of up to 50% can be achieved!

Discover the Presscon LOX

In the past decades we have structurally worked on the further development of the Presscon LOX "Low Oxygen System", based on our experience. 

All our products are developed and assembled in our own factory in Honselersdijk and have developed around our company's core values: innovation, quality and flexibility.
Because we have the production in house, we are a very flexible organization. This makes it possible to build to your specific requirements and deliver a custom installation that meets your needs, rather than a standard product range. In doing so, we ensure maximum safety of your product or process and significantly lower running costs. Presscon FX Prevent offers you competitively priced systems with long-term operation and cost-efficient maintenance.

Our goals

We are committed to creating the safest possible environment, working closely with our customers and their certifiers, such as the local authorities and insurers. We can support you in keeping employees, property and the environment safe from fire.
