Definitions

  • the present invention relates to an extinguishing agent container and a method for transporting and filling such, and a method for dispensing an extinguishing agent. Furthermore, the present invention comprises an extinguishing system at least comprising such an extinguishing agent container.
  • Extinguishing agent containers are usually used in the field of fire protection, for example in small extinguishing systems, such as cabinet protection extinguishing systems and the like.
  • the extinguishing agent containers must be filled with extinguishing agent and, if necessary, transported to the place of use, i.e. the place where the extinguishing agent is to be applied or where the extinguishing system is installed.
  • Transport usually has a number of disadvantages: For example, conventional extinguishing agent containers are subjected to high pressure or have a pyrotechnic element with which the extinguishing agent is released.
  • known extinguishing agent containers usually have incomplete emptying when in use. This means in particular that known extinguishing agent containers are not set up to be completely emptied when used properly. This has mostly constructive causes.
  • the object of the present invention is therefore to address at least one of the above-mentioned problems, to improve the general state of the art or to provide an alternative to the previously known.
