Abstract: A method of cleaning the adsorbent media of a rotary concentrator in-situ while maintaining operation of the concentrator, including directing washing liquid into the sectors in the desorb plenum, then rotating the sectors one full revolution plus at least one sector into the desorb plenum to bring a second sector into the desorb plenum, washing the second sector and repeating the cycle until all of the adsorbent media is washed. The method may also include directing washing liquid into sectors not located in the desorb plenum.
Abstract: A change station for atomizer (7) and other tools that contains a carousel-like rotatable and/or linearly movable mount (112) is arranged on the wall of the cabin of a coating installation. The arrangement is such that the storage locations of the change station are accessible both to the coating machine (151) in the cabin and from outside the cabin.

Abstract: Two steering air currents that can be controlled independently of one another are directed onto the atomizing cone from the steering air ring of an atomizer for the series coating of workpieces, e.g., car bodies, wherein said steering air currents emerge at different radial distances from the atomizer axis and serve to adjust the width of the spray jet in different regions, such that the spray jet of one and the same atomizer can be optimally adapted to the respective workpiece region to be coated.

Abstract: For the pig delivery of the coating material at high voltage in a system for electrostatic mass-production coating of workpieces in the vicinity of grounded parts of the system, a multi-layer tube is provided, whose innermost layer forms the piggable inner wall, while a second layer consists of a high-voltage-resistant isolation material and is surrounded by a protective outer layer.
