Inspection gas scrubber – packing replacement. Our gas scrubbers are conceived for easy replacement of the packing and other internals. The removed packing can either be cleaned and reused or replaced if necessary. This type of structured packing, as shown here, can be removed in one piece. According to the application and circumstances, either structured packing in block or loose bulk packing can be used. In normal circumstances, both loose bulk packing as the structured monobloc type of packing can be cleaned and reused.
