Wichmann: Zero Fire Risk Thanks to Active Oxygen Control
In sensitive areas such as archives, data centres, server rooms or automated storage systems, reactive extinguishing systems often reach their limits.
Fires and the methods used to extinguish them can not only cause operational downtime, data loss and financial and insurance damage, but also pose risks to personal safety due to the use of certain extinguishing media.
Why only one technology really prevents fires
An N2 ORS oxygen reduction system for active fire prevention, on the other hand, takes a much more effective, sustainable and preventative approach: it regulates the oxygen concentration in the room air and maintains it permanently so that a fire cannot start in the first place. For this purpose, nitrogen, which is extracted from the ambient air in an electromechanical adsorption process, is channelled into the respective protected areas in a targeted and needs-based manner.
One system - unlimited combination options
The N2 ORS system is characterised by its modular design: A total of 8 different VPSA generator sizes and 18 PSA generator sizes can be flexibly combined with each other and customised to the building to be protected. This philosophy enables versatile and customised solutions for every application scenario - whether in compact form for small server rooms or as a multi-level system for automatic storage systems. It is also a real game changer for compact container systems and in temperature-controlled logistics.
Maximum energy efficiency meets sustainability
With their minimal energy consumption (kW/Nm³), VPSA systems from the N2 ORS brand currently offer the most efficient system on the market and impress with their consistently high efficiency - a decisive advantage in operation and when considering the life cycle costs of a building.
They can also be easily combined with photovoltaic systems, fuel cells or heat recovery systems. This intelligent concept increases energy efficiency, promotes sustainable energy use and makes a significant contribution to CO₂ reduction - for maximum protection with minimum environmental impact.
Optical sensors for seamless and high-precision measurements
Oxygen measurement is also extremely efficient: the system's optical sensors are extremely low-maintenance and do not need to be replaced regularly compared to other oxygen sensor technologies - which significantly reduces operating costs. Three sensors per device ensure high-precision and seamless measurements. If required, the sensors can also measure the temperature or humidity.
Monitoring for remote surveillance
An IoT interface enables real-time monitoring: the system monitors all of the system's key figures and data, analyses them and automatically forwards important information - also in combination with data from other devices if required. It enables remote monitoring of additional parameters such as system runtime, alarm and fault messages, door contacts and temperature and humidity values. Not least thanks to the optional push notification alarm and BMS (Building Management System) connection, the monitoring system ensures maximum transparency and fast response times.
SIL 3: Certified quality for the highest possible reliability
N2 ORS is the only fully integrated system of its kind that is certified as a complete system in accordance with the Machinery Directive SIL 3 (Safety Integrity Level 3). SIL 3 is based on the international standard IEC 61508, which is also recognised in Europe and Germany as DIN EN 61508. It stands for a particularly high level of functional safety. Systems with SIL 3 must fulfil extremely reliable safety functions - safe operation must continue to be guaranteed even if several faults occur simultaneously. This applies in particular:
- Redundant nitrogen generators
- Redundant control (N+1)
- Multiple sensors with self-monitoring
- CAN bus dual structure
- Fail-safe MSR technology
In co-operation with the South Tyrolean company Isolcell, the global market leader for atmosphere control, Wichmann Brandschutzsysteme offers the N2 ORS systems exclusively in Germany and Switzerland, setting new standards in fire protection.
