Abstract: A method is proposed with which a content of formaldehyde in aqueous media that are conducted in a circular flow, in particular within a circular flow of a gas scrubbing installation, can be reduced in an economical and sustainable manner, wherein the formaldehyde in the aqueous medium is chemically bound during a predetermined reaction time in a reaction zone in the course of a formosis reaction in such a way that a release of formaldehyde from the aqueous medium into a gas phase at a temperature of 95° C., an ambient pressure of 1 bar, during a test time interval of 10 min is limited to a concentration of formaldehyde in the gas phase of about 1 ppm or less, wherein the aqueous medium for chemically binding the formaldehyde in the course of the formosis reaction in the reaction zone for the predetermined reaction time is held at a reaction temperature of about 50° C. to about 100° C. and the pH value of the aqueous medium is set to an alkaline pH value in the range of about 11 to about 14.

Abstract: The disclosure relates to a bell plate for a rotary atomizer for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The bell plate according to the disclosure comprises a metallic base body and a transponder which can be read out wirelessly and is integrated in the bell plate. The disclosure provides that the transponder is arranged on the front side in the base body or is embedded in the outer outer circumferential surface of the bell plate, which facilitates the read-out of the transponder. Furthermore, the disclosure comprises a suitably adapted atomizer cleaning device having an antenna for reading out the transponder in the bell plate. Finally, the disclosure also comprises a correspondingly adapted operating method.

Abstract: The present invention relates to a fluid purification system. The fluid purification system comprises a regenerative thermal oxidation device (RTO device) with a first combustion chamber and at least one regenerator. The RTO device is configured to purify a first fluid flow by means of regenerative thermal oxidation. Furthermore, the fluid purification system comprises a second combustion chamber separate from the RTO device, which is configured to purify a second fluid flow different from the first fluid flow by means of thermal oxidation. The fluid purification system further comprises a heat transport device configured to transport process heat from the RTO device to the second combustion chamber to set a temperature in the second combustion chamber.

Abstract: The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

Abstract: The disclosure relates to a coating device for coating components with a coating agent (e.g. paint), having a protected area which is explosion-proof and/or is under high voltage during operation and an unprotected area in which no explosive atmosphere prevails during normal operation. A plurality of sensors that measure process variables of the coating device are included with the sensors being arranged in the protected area. A data interface for external data communication, the data interface being arranged in the unprotected area is also included. A transmission system transmits data between the sensors in the protected area on the one hand and the data interface in the unprotected area. The disclosure additionally provides a collecting device in the protected area, the collecting device on the one hand being connected to the sensors and receiving measured values of the process variables from the sensors, and on the other hand being connected to the transmission system in order to transmit the measured values of the sensors to the data interface.

Abstract: The disclosure relates to a coating method for coating a component (e.g. motor vehicle body component) with a coating agent (e.g. paint), that includes steps of
Defining a pattern on the component surface of the component to be coated, the pattern being a surface area outlined by a contour, and
areal coating of the component surface with the coating agent within the contour,
sharp-edged coating of the component surface with a coating agent along at least a portion of the contour of the pattern.-

Abstract: The disclosure relates to a program-controlled coating robot for coating components. A robot path is preset and application parameters observed by the applicator are also preset based on real coating operation during movement along the robot path. There is a virtual determination of a coating result for the predetermined robot path and the predetermined application parameters. The disclosure provides steps for virtual determination of the coating result including generating real spray pattern data and/or reading out real spray pattern data from a database as a function of the predetermined robot path and/or the predetermined application parameters, the read-out real spray pattern data reproducing a spray pattern which the applicator generates during a real coating operation with the predetermined application parameters and/or on the predetermined robot path, and determining the coating result taking into account the real spray pattern data read out from the database or the generated spray pattern data.
