The exhaust gas after-treatment system of an engine configured as a gas engine or as a dual-fuel engine includes a catalyst, that can be flowed through by exhaust gas, a control tube extending through a recess in the catalyst, which control tube is movable relative to the catalyst and is flowable through by exhaust gas, and an actuator which is equipped to move the control tube relative to the catalyst dependent on at least one operating condition of the engine and/or at least one operating condition of the exhaust gas after-treatment system such that in a first relative position of the control tube relative to the catalyst, the catalyst can be flowed through by exhaust gas but not the control tube, and in a second relative position of the control tube relative to the catalyst, the control tube can be flowed through by the exhaust gas but not the catalyst.

In order to achieve effective cleaning of an inlet side of a catalytic converter in a combustion system, in particular a large-scale internal combustion engine system, a cleaning device having a cleaning brush for mechanically removing deposits is provided on the inlet side. The cleaning brush effectively and reliably removes and swirls up the deposits which have been formed, which are carried away with the exhaust gas in the flow direction through the catalytic converter.

An apparatus cabinet for providing process water, particularly for printing presses, having a housing with a top, intermediate and bottom level. A water conditioning device at the intermediate cabinet level a water-temperature control device having a coolant compressor arranged at the bottom level, a coolant condenser arranged at the top level, and a cooling blower device at the top level for conveying cooling air over the coolant condenser and out of the apparatus cabinet.
