Abstract: A device for controlling the temperature of, and in particular for drying, objects, in particular vehicle bodies, having a housing which integrates a temperature-control chamber that includes at least one air outlet and at least one air inlet. The temperature-control chamber is assigned at least one heating unit in which it is possible to generate a hot primary gas flow and to which it is possible to supply, from the air outlet, air that is to be heated. The heating unit includes a heat exchanger device into which the hot primary gas can be guided and in which it is possible to heat air from the temperature-control chamber using hot primary gas, which air can be supplied, as heated recirculation air, in a circuit via the at least one air inlet back to the temperature-control chamber. The heating unit includes at least a first and a second flow outlet via which heated recirculation air leaves the heating unit.

Abstract: A conditioning apparatus for conditioning a gaseous medium to form a conditioned gaseous process medium having an inlet connection unit and an outlet connection unit, between which there is formed a flow path for gaseous medium having one or more conditioning stages, of which at least one has a heat exchanger. The heat exchanger has a heat exchanger chamber in which a heat exchanger element is at least partially accommodated and to which gaseous medium for conditioning can be supplied, wherein, in the heat exchanger, there are sensitive material regions which can be damaged by the gaseous medium. A heat exchanger protection system is provided by means of which such sensitive regions of the heat exchanger can be impinged on with a protective gas. Also specified are a method for conditioning a gaseous medium, and an installation and a method for treating workpieces.

Abstract: An apparatus for treating articles, in particular vehicle bodies, with at least one tempered, directed air jet comprises a housing, in which are formed a treatment chamber and at least one pressure chamber, which is separated from the treatment chamber by a partition wall. The tempered air is suppliable to the pressure chamber and may then flow as a directed air jet into the treatment chamber through a nozzle device, which penetrates an opening of the partition wall. The nozzle device is insertable from the treatment chamber into the partition wall and fastenable from the treatment chamber to the partition wall. Consequently, subsequent work on the nozzle device, in particular an exchange thereof, may be carried out more easily.

Abstract: The invention relates to a dryer for objects, in particular for motor vehicle bodies (1). Known dryers comprise a drying tunnel (6), located within an insulated housing (2), a number of nozzles (25) being arranged in the lateral walls (8) of said tunnel. These nozzles are used to direct hot circulatory air against the objects (1). The circulatory air is extracted from the drying tunnel (6) by means of extraction openings (7) below the objects (1) and is supplied to two air chambers (13) located at the sides of the drying tunnel (6). The circulatory air is extracted upwards via said chambers with the help of fans (18). A heat register (26) is located in each of the two air chambers (13) and is aligned in a substantially vertical direction, said registers consisting of a number of intercommunicating pipe sections that are traversed by hot primary air and are surrounded by the circulatory air.

Abstract: A drier for a lacquering line in a known manner comprises inside a drier housing a plurality of drier sections, in which heated circulating air is circulated with the aid of fans. Heating of the circulating air is effected with the aid of a heating unit, which is common to all drier sections, and a common fresh-air heat exchanger, which is disposed downstream of the heating unit and to which fresh air is supplied from the environment via a pressure regulator. The fresh air heated in said manner is directed via branch lines to the individual drier sections. The quantity of heated fresh air supplied and hence ultimately the temperature in the respective drier section is determined by control flaps in branch lines, which connect a common fresh-air distribution line to the respective sections.
