Recycling plants

Depending on the operating process, raw-, auxiliary- and operating materials are stored in outdoor areas or delivered and often also stored in a shed. Frequently both storage options are found in a processing operation.

• Stored materials may quickly ignite themselves
• Dust can cause a potentially explosive atmosphere to arise

Dumps situated outside are generally monitored with infra-red cameras for undesirable build-ups of heat. If there is a threat of ignition, a signal is transmitted to the connected fire detection control panel. Extinguishing monitors aimed manually or by remote control at the target provide for effective fighting of the so-called hot spot via water enhanced with film forming foam compound. Facilities nearby that are threatened by a fire are also selectively cooled with extinguishing monitors.

Internal storage areas on the other hand are securely protected against fire with sprinkler systems. Deluge systems provide for reliable fire fighting for ceiling heights above 15 meters. In this case automatic release of the extinguishing system is via a fire detection system. Smoke aspiration systems of the HELIOS AMX5000 type or UniVario flame detectors are used for detection.

Server rooms are important, sensitive areas. In these rooms, data of high importance for business operations is stored, managed and exchanged over the network. The irretrievable loss of this data through a fire may have considerable economic consequences for productivity or even the future of a company.

• Overheating of technical equipment
• Defects such as short circuits
• Considerable damage even in the case of small fires

For small and medium-sized server rooms, the MX 1230 extinguishing system is the ideal solution. It gives residue-free extinguishing using the innovative FK 5-1-12 extinguishing agents and requires very little space. Oxeo inert gas extinguishing systems are ideal for large server rooms. The MX 1230 extinguishing system and Oxeo inert gas extinguishing systems are triggered, and fires are detected, by a fire detection system using a HELIOS AMX5000 smoke aspirating system.

Offices, conference rooms and dining rooms are generally used by staff and guests. In addition, staff members may also retire to break rooms or smoking rooms and to kitchens during work. Corridors run through the entire building, serving as a main traffic route.

• Defective electrical devices such as projectors and computers
• Overheating of the lighting
• Short circuits at vending machines

Minifog EconAqua water mist extinguishing systems offer space- and water-saving protection and can be connected to an existing sprinkler system. In areas with higher ceilings, sprinkler systems provide reliable fire protection. 

Control rooms are very sensitive and high-quality facilities which control fundamental production processes. They contain electric switching and control equipment plus false floors with extensive cabling. Even minor defects may cause substantial operational failures.

• Short circuits
• Highly flammable materials

Oxeo inert gas extinguishing systems offer reliable protection in control rooms. For smaller control rooms, MX 1230 extinguishing systems offer an economical alternative. The extinguishing system is triggered by a fire detection system using punctiform smoke detectors or HELIOS AMX5000 aspirating smoke detectors.

Recyclable materials are often divided, sorted and sometimes processed. In order to obtain the so-called separated fractions, a large number of various steps are necessary in the recycling process. This includes different technologies and machines for operation such as vibrators, drum separators, magnets, shredders, mills, or air separators.

• Hot-running roller bearings or compressors with technical defects
• Sparks during maintenance- and welding work
• Spontaneous ignition of the material being transported
• High concentration of material in a narrow space and hence high fire load

Because fires quickly develop and spread, for this fire risk deluge systems with an admixture of film forming foam compound have above all proven themselves. The immediate and wide-area release and fire fighting over the defined area for protection provides for maximum safety. An alternative and more innovative solution is represented by Minifog ProCon water mist extinguishing systems. The crucial advantage of these systems is that in comparison with deluge systems they fight effectively with significantly less extinguishing water.

A fire detection system releases the extinguishing system. The combined installation of UniVario flame detectors and multisensor gas emission detectors ensures early and nuisance-safe fire detection in these areas.

During the entire production process, the raw materials, auxiliaries and consumables are transported to the next processing stations through enclosed or open conveyor belt systems.

• Overheated roller bearings
• Sparks generated during maintenance or welding works
• Spontaneous combustion of the material to be conveyed

Deluge systems are ideal for protecting conveyor belts against fire, as the rapid spreading of fire requires immediate and large-scale activation or extinguishing across the entire protected area. Minifog ProCon water mist extinguishing systems are an efficient alternative for the direct protection of conveyor belt systems. A significant advantage is that this system uses considerably less extinguishing water compared to deluge systems. Detection of fires and triggering of the extinguishing system is via a fire detection system equipped with UniVario flame detectors and multisensor fire gas detectors.

The areas where flammable materials are pneumatically extracted or transported presentan increased risk of fire. This particularly applies to the material mix in the extraction and conveyor systems.

• Sparks, hot particles or glowing embers in the processing machinery that penetrate into the conveyor systems
• Dust explosions

Function-monitored spark detectors respond reliably and immediately to the infrared radiation of passing ignition sources. They transmit a signal to the fire detection system, which consequently activates the solenoid valve of the automatic extinguishing systems within milliseconds. The extinguishing water is released through self-closing nozzles into the conveyor flow. The glowing particles fly into the water mist formed by the extinguishing nozzle and are thus extinguished. Immediately afterwards, the solenoid valve closes automatically.

When fractions are being agglomerated using baling presses and briquetting plants, the materials that were previously separated from one another are concentrated together for further treatment.

• Hydraulic- and thermal fluids in the processing machines may accumulate
• Hot surfaces on which fluids ignite
• Leakages in oil-carrying lines

Conventional deluge systems with foaming agent admixture make a reliable solution for the hydraulic systems built into the processing machines. The “Minifog ProCon water mist extinguishing systems for hydraulic systems” protection scheme is an innovative alternative. The recognized design developed in collaboration with insurers and operators manages with considerably less extinguishing water than with conventional deluge systems. UniVario flame detectors guarantee rapid detection, and a fire detection system triggers the extinguishing system.

In sorting cabins, recyclable materials and subgroups are manually presorted. The cabins are encapsulated areas which are traversed by conveyor belts. So-called manual workplaces are situated on both sides of the conveyor belts.

• Defects in electrical equipment for ventilation or air conditioning
• Hot-running roller bearings in mechanical belt systems
• Ignition of dust particles

In these areas, building protection in the form of a sprinkler systems ensures reliable fire protection. In order to ensure particularly early detection of fire, the fire detection system releases the extinguishing system.
