Abstract (en)

[origin: EP2317274A2] The device has a blast connection (209) provided with nozzles for admission of cooling pipes with pressurized water, where the pipes are arranged in cooling coils (201, 202). The connection is movable in a longitudinal direction of the pipes and transverse to the longitudinal direction. The connection is movable in or on two parallel arranged profiles, which are fastened to a ladder consisting of side walls and ladder rungs. The profiles and the ladder are made of aluminum. The profiles are welded with the side walls, where welding seams consist of welding seam pieces with certain distance. An independent claim is also included for a method for operating a cleaning device.
