Fire prevention

Fire prevention – maximum safety

Whether it’s a warehouse, data centre, or archive: For companies and institutions, reliable fire protection is crucial for maintaining operations, avoiding downtime, and protecting valuable assets. Fire prevention systems that operate on the principle of oxygen reduction offer a particularly effective solution for this purpose. Under defined conditions, they prevent fires from starting or spreading at the very outset, thereby ensuring the highest level of safety for processes, assets, people, and the environment. At the same time, they prevent secondary damage that can occur when fighting fires with water-based extinguishing agents.

FUNCTIONAL PRINCIPLE

Active fire prevention through oxygen reduction

For a fire to start, three components must be present: oxygen, heat, and fuel. If one of these components is removed, a fire has no chance of de­veloping. By reducing the oxygen level in the area to be protected, the fire is literally "cut off" from the air it needs to breathe.

If oxygen is removed from the fire by displacing nitrogen, the fire can no longer burn. The fire triangle is dissolved.

Active fire prevention systems are based on the principle of oxygen reduction. They generate generate nitrogen from the ambient air and introduce it directly into the protected area. This reduces the oxygen concentration to below the specific ignition limit of the materials present. In the resulting protective atmosphere, the development of a fire is ruled out under defined conditions.

Recognised

Oxygen reduction systems can be designed according to various guidelines, such as VdS, FM, EN, ISO, ÖNORM or SES. These systems are recognised by many local authorities and insurance companies.

Continuous monitoring of the O2 concentration to ensure a reliable level of protection 24/7.

APPLICATIONS

Fire prevention in action

Active fire prevention is particularly suitable for areas in which, in addition to basic personal protection, the ability to deliver goods, the protection of valuable assets and the availability of electronic systems have the highest priority. Typical areas of application are automated warehouses, data centres or archives.
