New Jetting Tool To Clean Tube Bundles Saves Thousands Off Dollars The new high-pressure hydraulic tool, shown above, is currently saving thousands of dollars for companies in the refining, chemical, and petrochemical industries. It is the jetting tool developed by Dowell to remove deposits from heat exchanger tube bundles. Previous methods of cleaning these bundles have been costly, time-consuming and often inadequate. Many times bundles had to^be replaced completely because of the lack of a suitable cleaning method. This new Dowell tool has a remarkable record of thorough, fast cleaning. For example, a slurry reboiler exchanger bundle, three feet in diameter and 16 feet long, was fouled with deposits of coke and asphalt. After being jetted from only one side, the bundle was

thoroughly clean. Time required: less than one hour. The tool holds the bundle in place for cleaning and has flanged rollers for rotation. T h e jet-head is manipulated automatically so that all tube spaces are covered. The jetted liquid can be either water or chemical solvents. This high-velocity jetting device is another example of the new ideas Dowell continues to offer in chemical cleaning to help you cut your costs. Whatever the cleaning problem in your plant, call Dowell for an engineered recommendation.
