Abstract: A sealing profile for sealing a gap between a door and a door stop comprises a hollow profile having a wall with a wall inner side and a wall outer side, where the wall inner side defines a hollow volume. The hollow profile includes a profile foot, a first sealing lip having a first sealing lip first end and a first sealing lip second end, and a second sealing lip having a second sealing lip first end and a second sealing lip second end. The profile foot is substantially U-shaped and comprises a first profile foot shank, a second profile foot shank that is longer than the first profile foot shank, and a profile foot bottom.

Abstract: A ventilation unit for a low temperature chamber with a tube-shaped base body, having a heating element, an inlet side end with an inlet opening and an outlet side end with an outlet opening, wherein the base body has a tapered form such that the inlet opening has a greater area than the outlet opening. The inlet opening can be located in a first front side plane and the outlet opening can be located in a second front side plane, wherein the first front side plane and the second front side plane are substantially parallel offset with respect to one another, and wherein at perpendicular projection of the first front side plane onto the second front side plane, the inlet opening and the outlet opening are disposed offset with respect to one another. The base body can have a mechanical valve configured to open under pressure induction.
