Aerosol Suppression System for Mining Equipment

» PRODUCT » Aerosol Suppression System for Mining Equipment

  • Thermal Activation Aerosols for String Combiner Box and Monitoring Boxes

    Thermal sensing line aerosol generators range from 30 grams to 100 grams, are now popular fire extinguishing systems and are now recognized as the perfect fire protection solution for string combiner boxes and string monitoring boxes.

    • Specifications
    • Main Features
    • Other Application Fields

    String Monitoring Boxes are an electrical device that collates the electrical input from individual strings of a solar array, they serve as an advanced version of combiner boxes involving the collation of multiple strings of solar PV modules to transfer a single main output to inverters. we called it “SMB” for short.

    while string combiner boxes are a significant straightforward device. It allows a PV array to transition from a multi-wire output to a single-wire output. we named it “SCB” for short.

    No matter string monitoring box or a string combiner box, they are all electrical devices, Under the condition of high temperature and aging of electrical components, it is easy to get thermal runaway.

    The approximate size of a string monitoring box or string combiner box is between 0.1 to 1 cubic meter, this is narrow space. so when relevant regulatory agencies require us to install a fire extinguishing device in the string monitoring box or string combiner box, we will not hesitate to recommend aerosol systems, mainly due to the following reasons:

    • Small in size, Does not occupy limited space, and can be installed in narrow spaces.
    • Compact in agent, the efficiency of spraying fire extinguishing is very high, and the extinguishing speed is also fast.
    • Aerosol compound belongs to a clean extinguishing agent, will not pollute the environment, and cause damage to the Electronic components in the box.

    Which one is suitable? The recommended style is: 30 grams one, 60 grams, and 100 grams one:

    • For space not over 0.3 m³, to install 30 grams of aerosol, model AW-QH-30 TH.
    • For space not over 0.6 m³, to install 60 grams of aerosol, model AW-QH-60 TH.
    • For space not over 1.0 m³, to install 100 grams of aerosol, model AW-QH-100 TH.

    For more technical details about the product, you can see it from the following list:

    • Basic description: 30 grams, 60 grams, 100 grams aerosol with thermal cord activation aerosol suppressant.
    • Application field: String monitoring box, string combiner box.
    • Activated mode: thermal cord, thermal line, thermal sensing cable.
    • Rated temperature: 175℃  or 300℃.
    • Length of thermal cord: 0.3 meters adjustable.
    • Extinguishing time: not over 15 seconds.
    • Aerosol concentration: 100g/m3.
    • Fire rating: A, B, C, E fire.
    • Safety distance for personnel during spraying: 3 to 5 meters.
    • Minimum distance between device and obstacle: 1 meter.
    • Environmental protection situation: GWP value is zero, OPD value is zero, ALT value is low.

    The reason why aerosols are widely used abroad is because they have been proven by users to be an efficient and feasible fire extinguishing system.

    Among numerous fire extinguishing systems and equipment, the advantage of aerosols is very obvious.

    Let's list the advantages as follows:

    • The concentration of the agent is highly integrated and compressed, which can be stored in a solid state and then sprayed in a gaseous form to extinguish the fire.
    • The aerosol cylinder is made of high-density 304 stainless steel, with fine workmanship, waterproof, dustproof, and corrosion-resistant. Because its space is enclosed, the agent is insulated from the external air, which can extend the service life of the agent.
    • The product size is very small and can be installed in various narrow spaces and environments.

    Aerosol fire extinguishing systems can be applied not only to various traditional industries such as manufacturing and agriculture but also to various new industries such as new medicine, new energy, life sciences, etc.

    Let's take a look at its specific applications below (but not limited to):

    • Charging station and charging pile.
    • Container energy storage.
    • Lithium battery packs.
    • Battery energy storage system.
    • Production machinery and CNC machine tools.
    • Banking and financial equipment, For example: ATM.
    • Agricultural modernization production machinery, For example: harvesters, lawn mowers.
    • Modern means of transportation: such as high-speed trains, subways, airplanes, buses, and cars.
    • Heavy-duty machinery, for example, Bulldozers, excavators, forklifts, cranes, and various other construction and firefighting machinery.
    • Electrical equipment for various distribution rooms, and transmission rooms.
    • Port operation machinery fire protection, such as cranes, loading and unloading machines.
