  • the extinguishing clouds leaving the entrances / exits are uncleaned and mixed with dirt particles. Persons and buildings are affected by the swaths leaving the entrances / exits.
  • the free cross section of the entrances and exits is adapted to the profile of the fire truck used.
  • this may be limited by the fact that for the passage of the Löschwagens to the other side of the extinguishing tower a larger profile is to be kept clear because z. B. the extinguishing locomotive has a greater clearance profile in height or in width than the fire truck. Another reason may be the leadership of the tracks for the fire truck in the area of entry / exit, for example in a curve.
  • the object of the invention is to reduce leaks at entrances and exits of a wet extinguishing tower. In doing so, the production should be influenced as little as possible. In particular, time-consuming operations should be avoided.

  • the air flow prevents extinguishing swaths emerge at the entrance / exit and / or catches escaping extinguishing swaths directly at the entrance or exit of the wet extinguishing tower.
  • the inflow of air into the quenching tower is not prevented, but escaping extinguishing swaths are intercepted.
  • an air curtain is generated in front of the entrances and exits of the wet extinguishing tower.
  • air is sucked in from the environment and blown out horizontally or vertically, producing an air curtain covering the entry / exit in height and width.
  • the wet extinguishing tower has at least one air curtain generating device. This comprises at least one arranged on the side of the entrance / exit or above the entrance / exit device which sucks in air from the environment and blows out to produce the air curtain covering the entrance / exit in height and width.
  • the air curtain separates differently conditioned air masses inside and outside the wet extinguishing tower by a barrier of flowing air, thus preventing their replacement.
  • the barrier consists of a directed air flow, which circulates in the manner of an air roller between the discharge opening and the intake opening of the device.
