Experts in fire protection

Overview

The production process in wood-processing plants is characterized by complex processing areas where machines are used for crushing and separating, drying, gluing and pressing, planning, milling and sawing. The individual processing areas are interconnected through various mechanical and pneumatic conveyor systems to ensure effective handling of the wood material. In addition, wood-processing plants often have various auxiliary areas that may range from powerhouses with turbines and transformers to different types of storage and server rooms.

Increasing automation and ever higher production speeds cause a tremendous increase of the risk of an outbreak of a fire. If sparks or glowing particles are generated, fires can spread rapidly to other processing areas due to the closely interconnected production processes. The high fire load of wood in combination with the generation of fine dust particles can quickly cause fires and explosions that can bring the entire production process in a wood-processing plant to a standstill. 

Flames, smoke, gas emissions, heat – fire has many facets. Minimax has the right fire detectors for the various areas within a wood-processing plant. Their signals converge in the fire detection and extinguishing control panel, which issues an alarm to the people at risk and the fire brigade. In addition, the Minimax panel monitors the installed fire protection systems for proper functioning and electrically triggers those extinguishing systems that are not equipped with their own triggering elements, e.g. sprinkler systems.

A sprinkler system ensures overall building protection in a wood-processing plant. Minimax offers a broad range of sprinkler types and special sprinklers that allow for ideal adaptation of the sprinkler system to the respective installation situation in the individual protected areas.

Areas with special fire risks or deployment conditions require - either in addition to or instead of the sprinkler system - a tailored volume- or equipment protection system. Therefore, deluge extinguishing systems, Oxeo inert gas extinguishing systems, carbon dioxide extinguishing systems, halocarbon extinguishing systems and spark extinguishing systems are also used in wood-processing plants.

The alarm and condition reports issued by the fire protection systems installed by Minimax, as well as by other suppliers, can be visualized on screens by the Inveron hazard management system.

Structural fire protection, as well as technical systems by Minimax Mobile Services, such as fire extinguishers, wall hydrants and smoke and heat extraction systems, complete fire protection in wood-processing plant.

    Protection zone

    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.

    Risks

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

    Fire Protection

    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.

  7. Electric & control rooms
    7 Electric & control rooms

    Protection zone

    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.

    Risks

    • Short circuits
    • Highly flammable materials

    Fire Protection

    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.

  8. Offices
    8 Offices

    Protection zone

    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.

    Risks

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

    Fire Protection

    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. 

  9. Server rooms
    9 Server rooms

    Protection zone

    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.

    Risks

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

    Fire Protection

    For small and medium-sized server rooms, the MX 1230 extinguishing system is the ideal solution. It gives residue-free extinguishing using the innovative Novec™ 1230 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.

  10. Storage of hazardous substances
    10 Storage of hazardous substances

    Protection zone

    Hazardous substances are materials or mixtures that are explosive, combustible or harmful to human health or the environment. Warehouses where such substances are stored have a great variety of typical designs, subject, however, to specific laws and regulations applicable to their construction. Such provisions require e.g., fall-safe storage, soil protection in the form of collecting reservoirs and extinguishing water retention systems as well as the prevention of operational sources of ignition.

    Risks

    • Rapid spread of fire
    • Devastating effects of fire on people and the environment

    Fire Protection

    As a rule, the planned fire protection system for hazardous substance storage is determined in particular by the characteristics of the stored goods. Accordingly, nearly the full range of fire extinguishing systems is used in such facilities. For this type of storage, Oxeo inert gas extinguishing systems are often the preferred solution: they extinguish fires quickly without leaving residue, and reactions between the burnt materials and extinguishing agents are precluded. Alternatives are Oxeo Prevent oxygen reduction systems or foam extinguishing systems. A fire detection system triggers Oxeo inert gas extinguishing systems and Oxeo Prevent oxygen reduction systems. UniVario flame and heat detectors are used for detection purposes.

  11. Mechanical conveyor systems
    11 Mechanical conveyor systems

    Protection zone

    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.

    Risks

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

    Fire Protection

    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.

  12. Sorting machines
  13. Outside storage
  14. Bunker, silo, cyclones
  15. Filter systems
    15 Filter systems

    Protection zone

    Filter systems are used whenever the production process generates fumes, or when dusts are released through abrasion. Fine dusts occur for example, when milling or cutting plastics or when processing other materials.

    Risks

    • Explosive atmosphere
    • Highly flammable dust in the filter bags

    Fire Protection

    Carbon dioxide extinguishing systems are ideal for protecting filter housings against fires. In the case of metal extraction, however, the Oxeo extinguishing system using the argon extinguishing agent is the right choice to preclude interactions of the extinguishing agent with combustible metal. A fire detection system will trigger the extinguishing system.
