Type LT & LT-FT Tank Cleaning Machines

The Butterworth Type LT automated tank cleaning machine provides 360° impact indexed coverage for the cleaning of the inside of tanks and process vessels.

The Butterworth LT is a highly versatile machine and is applicable in most all types of tanks for process, storage, and transportation. Tank capacities range from 500-150,000 gallons (2-570 M3) for one machine per tank and larger tanks where multiple machines are installed.

The Butterworth LT machine creates a pattern matrix similar to a ball of twine (see cleaning pattern simulation in the lower right hand corner of this page). A complete pattern is established when 65 axial revolutions of the body have been completed. During the process of this pattern build out, 4 cycles are established with each cycle increasing the density of the pattern matrix.
