  • the pressurized fluid is a relative to the environment below
  • the pressure fluid can be compressed air, for example.
  • the invention causes a modification of the application characteristics of a cooling liquid volume flow onto the product to be cooled.
  • the invention brings about a modification of the overrun characteristic in that the overrun from the cooling beam is prevented or at least largely reduced.
  • This is accompanied by an improvement in the characteristics of the application of the cooling liquid to the product to be cooled, in particular with regard to a temporal and spatial characteristic and controllability. This enables a higher process speed, improved process stability and - dynamics and a higher productivity of a system equipped with the device according to the invention can be achieved.

  • a procedural introduction of the pressure fluid into the flowing cooling liquid can be achieved in a way that improves the characteristics of the temporal and spatial application of the cooling liquid to a product to be cooled in such a way that the properties generated on the product are optimized.
  • the cooling liquid can for example be water with or without an additive.

  • the device according to the invention can be used for applying liquid and gaseous media to substrate bodies, for example in the paper, metal or plastics industry.
  • the device has at least one arrangement for switching on and off a supply of the cooling bar with the cooling liquid and at least one control electronics for controlling the device and the arrangement, the control electronics being set up to control the device and the arrangement in such a way that the pressure fluid is introduced into the coolant chamber immediately after the supply of the cooling bar with the cooling liquid has been switched off.
  • the sudden introduction of the pressurized fluid into the coolant chamber is synchronized with the shutdown process and is carried out immediately after the shutdown process, in order to be able to prevent continued running as quickly as possible.
  • the device has at least one arrangement for switching on and off a supply of the cooling bar with the cooling liquid, the arrangement having at least one pneumatic control element which is kept open while the cooling bar is being supplied with the cooling liquid with compressed air, and wherein an outlet opening of the pneumatic control element is connected to the coolant chamber in a communicating manner via at least one compressed air line.

  • the compressed air line is arranged relative to the outlet opening of the pneumatic control element and the coolant chamber in such a way that the compressed air line forms a siphon when the cooling bar is displaced.
  • This line routing from the pneumatic control element to the point of introduction into the cooling beam prevents the cooling liquid from entering the pneumatic control element, in particular when the cooling beam experiences a change in position.
