WAGNER offers operators of warehouses and logistics centres innovative fire protection concepts that ensure operational safety and help protect people, processes and products: the OxyReduct® active fire protection system reduces oxygen concentration levels within a previously defined protected area, preventively inhibiting fires from developing or spreading. Unlike sprinkler-based fire protection, oxygen reduction prevents fires from starting in the first place.
WAGNER’s highly sensitive TITANUS® air sampling smoke detector (previously known as aspirating smoke detector) can detect fires with 2,000 times more sensitivity than conventional smoke detectors, thus providing a crucial head start in the event of fire. Despite their high sensitivity, these air sampling smoke detectors are extraordinarily safe from false alarms, thanks to built-in filters, LOGIC∙SENS intelligent signal processing, and drift compensation.
FirExting® gas extinguishing technology is WAGNER’s contribution to the field of fire suppression. These automatic gas extinguishing systems use inert gases (nitrogen, argon, CO2) to suppress fires. The advantages these extinguishing agents offer are that they are efficient and leave no residue. Goods remain free from the water damage that frequently results from extinguishing with conventional sprinkler systems, so processes can be resumed immediately.
Planning storage buildings—regardless of whether they are new structures, building conversions, or expansion constructions—requires taking a variety of fire protection-related regulations and legal guidelines into account. Requirements as regards fire protection primarily stem from building laws. These governmental specifications should only be seen as minimum requirements, however, and only cover a limited number of protection objectives. Additional measures are often necessary in order to fulfil insurance company requirements regarding fire protection. Generally speaking, these additional measures are also necessary in order to achieve additional protection objectives, such as property protection or road-safety obligations. The individual operator’s requirements regarding fire protection also play a role when it comes to planning fire protection measures. For example, an operator may elect to put more extensive fire protection measures into place for reasons of personal responsibility, safeguarding, or ensuring operational processes. In summary, the following requirements must be taken into account when planning fire protection systems:
However, companies come in a wide range of sizes and have a wide range of needs, which makes it impossible to create a single, generally applicable model for determining the necessary fire protection measures. As such, it is important to involve a fire protection expert in the planning stages of warehouse and logistics centre construction projects, so that he or she can create a fire protection concept tailored to the individual needs of that project.
As experienced systems engineers, WAGNER specialises in planning and designing fire prevention systems for warehouses and logistics centres. The company numbers among the global technology leaders in the fire prevention sector.
When planning fire protection systems, it is important to ensure that technical, structural, and organisational facets of fire protection mutually reinforce one another. Fire suppression and/or prevention can only succeed if these various facets work in harmony. For example, system planning should ensure that different fire protection measures will not hinder each other. Planning a sensible combination of complementary measures can ensure that the resulting solution is both technically and economically efficient.
Companies need to fulfil a variety of fire protection-related regulations and guidelines. The following regulations are important in this regard:
According to § 3 of the Model Building Code, upon which state building laws are based, building systems are to be configured, constructed, modified and maintained in such a way that they do not endanger public safety and order, especially life, health and livelihoods. § 14 specifies that building systems are to be configured, constructed, modified, and maintained so as to prevent the outbreak or spread of fire or smoke (fire spread), and such that, in the event of fire, it is possible to save humans and animals, and to conduct effective fire suppression work.
Whether it’s an automated high-bay warehouse, a deep-freeze storage area or a hazardous materials storage building, each type of rack storage facility involves different conditions and has its own specific set of risks from a fire protection technology perspective. Therefore, they also have different requirements in terms of optimum fire protection concepts. In automatic high-bay warehouses with small load carriers (small parts storage), the plastic small load carriers create a challenge in the event of fire: their fire behaviour is comparable to that of burning petrol. In deep-freeze storage facilities, meanwhile, the frost does not protect goods from fire—a predominately dry atmosphere and highly combustible packaging materials both facilitate the spread of fire. Our special-topics pages give you a look at sophisticated, customised fire protection solutions.
WAGNER develops its own technologies and products, setting new standards on the market again and again. Our in-house development work has resulted in up to 700 patents thus far. All of the systems and products we use have been tested and certified. We also have VdS Schadenverhütung GmbH (Organisation of Property Insurers) approval as installers. This recognition is an expression of high quality and reliability, and is of central importance to both owners and operators. VdS Schadenverhütung GmbH is accredited for a variety of inspections and certifications as per DIN, ISO and EN standards, and is a member of the European Fire and Security Group (EFSG).
1 OxyReduct® generator (VPSA technology): Extracts nitrogen from room air on location and uses it to reduce oxygen concentration levels within the protected area
2 Supply air (room air)
3 Exhaust air (O2)
4 N2 infeed pipe: Feeds nitrogen into the protected area, where it is generally distributed via an air recirculation system
5 OxyControl central controller: Manages processes for the entire OxyReduct® system
d6 Selector valve: Opens/closes nitrogen supply valves for specific areas
7 Area regulator 1 and 2: Work together with OxyControl to monitor oxygen content and adjust it to within defined protection levels
8 OXY-SENS® O2 Sensor: Continuously measures oxygen concentration levels within the protected area
9 OXY-SENS® SIL2 Sensor: Provides supplementary oxygen concentration measurements and activates sector valve closure when they drop below 12% vol.
10 Area display: Shows the current oxygen concentration levels within any given protected area
11 TITANUS® air sampling smoke detector: Active fire detection using air sampling to identify smoke early on
12 Needs-appropriate protection concepts: Multiple protection schemes and oxygen concentration levels may be employed in order to keep protected areas accessible, e.g., unrestricted access for personnel or restricted access for maintenance purposes
VisuLAN® risk management makes it possible to monitor and manage a variety of building technology, communications, and security systems centrally. This minimises security risks and operating errors, and makes it possible to take appropriate emergency response action quickly, in order to prevent more serious damage.
