  • process air is sucked in via the at least one inlet hose.
  • the process air is humid air, which comes from the insulating layer to be dried, which is fluidly connected to the device 101 via the tubing.
  • the moist process air flows in accordance with the arrows 122 in the vacuum chamber 102 a. There it comes with the help of the water separator 103 to a separation of water from the humid air.
  • the dried process air so far is released via the at least one process air discharge hose in the atmosphere surrounding the device 101, possibly also to the outside.
  • the volume space 112 housing the housing electronics 113 is in fluidic connection 118 with the vacuum chamber 102.
  • this fluidic connection 118 is achieved by three passage openings 119, which are bores formed in the wall 114, as shown in particular the illustration Fig. 7 lets recognize.
  • the fluidic connection 118 ensures in the case of operation due to the vacuum forming in the vacuum chamber 102 that is sucked out of the volume space 112 in accordance with the arrow 123 air, which is then mixed in the vacuum chamber 102 with the process air and discharged.
  • a cooling of the device electronics unit 113 is achieved by heat dissipation in an advantageous manner.
  • the second compartment 109 of the housing 107 which provides the volume space 112, is substantially dense in order to protect the electronics unit 113, in particular, splash-proof. Nevertheless, the compartment 9 is not hermetically sealed off from the atmosphere surrounding the device 101, so that air can flow into the volume space 112 through device slots, expansion joints, screw holes and / or similar openings in correspondence with the arrows 124, so that there is compensation for the result the vacuum created by the air suction comes.
  • the embodiment according to the invention advantageously makes it possible to make the volume space 112 dense for the most part, which serves to protect the device electronics unit 113. Unintentional dust and / or water entries in the second compartment 109 are thus largely excluded to protect the device electronics unit 113. Nevertheless, despite this largely dense configuration of the volume space 112, a cooling of the device electronics unit 113 is ensured by hot air removal, which increases the reliability and longevity of the device 101. In this case, the removal of hot air from the volume space 112 takes place due to the fluidic connection 118 between the volume space 112 and the vacuum chamber 102.
  • a one-way valve can optionally be provided which opens the fluidic connection 18 only when a specific vacuum is present within the vacuum chamber 102.
