Work Piece Cleaning Apparatus and Method with Pulsating Mixture of Liquid and Gas

NASA Goddard’s scientists have developed a novel, volatile organic compound (VOC)-free system for cleaning tubing and piping that significantly reduces cost and carbon consumption. The innovative technology enables the use of deionized water in place of costlier isopropyl alcohol (IPA), and does not create any waste for which costly disposal is usually required. It uses nitrogen bubbles in water, which act as a scrubbing agent to clean equipment. The cleaning system quickly and precisely removes all foreign matter from tubing and piping.
