  • Publication number: 20070074744
    Abstract: An aqueous tube cleaning system as described herein can be utilized to clean a plurality of tubes having different lengths. The system includes a tower assembly having a wash chamber that houses the tubes during the cleaning cycle. The tower assembly is held in a horizontal load/unload position for loading and unloading of the tubes. The system rotates the tower assembly into a vertical cleaning orientation to accommodate cleaning with cleaning and rinse solutions, which flow through and around the tubes using the force of gravity. After rinsing and draining, the tower assembly is rotated back to the horizontal position for unloading.

  • Publication number: 20060169302
    Abstract: An aqueous tube cleaning apparatus and method includes a cleaning receptacle and a vertical receptacle, which is taller than the cleaning receptacle. A tube, or bundle of tubes, is placed in the cleaning receptacle, extending through an inlet port from the vertical receptacle, and a gate is closed to clamp the tubes in place. The vertical receptacle is then filled with a fluid, and the pressure created by gravity forces the fluid through and around the tubes, cleansing the inner and outer surfaces of the tubes.
