An installation has a process chamber defining an inner space having a tunnel-like form defining a receiving region for workpieces. The process chamber has a portal for the supply or discharge of workpieces and has a device for introducing gaseous fluid into the inner space. The device has a nozzle for producing a fluid stream curtain between the portal and the receiving region. A device supplies fresh air introduced into the receiving region at a side of the fluid stream curtain facing away from the portal. The installation has a pivotable guide contour projecting into the inner space and the nozzle or aperture is in the form of a slot which supplies the gaseous fluid to the inner space via the ceiling with a flow direction oblique relative to the floor. The gaseous fluid supplied via the nozzle to the inner space is guided on the guide contour.

System having a process chamber for workpieces

The invention relates to an installation having a process chamber which comprises an inner space having a receiving region for workpieces. The process chamber has an opening for the supply or discharge of workpieces. The process chamber is constructed so as to have a device for the introduction of gaseous fluid into the inner space, which device has at least one nozzle or aperture for the production of a fluid stream curtain between the opening and the receiving region for workpieces. The process chamber has a device for supplying fresh air, with which device fresh air can be introduced into the receiving region at a side of the fluid stream curtain, which side faces away from the opening.
