Type DW (Directional Washer) Tank Cleaning Machine

The Butterworth Type DW automated tank cleaning machine provides directional impact cleaning of the inside of open top tanks.

The Butterworth Type DW is typically used in open top tanks, such as those found in the oil & gas and food and beverage markets. The Type DW has the ability to clean tanks to a capacity of up to 10,000,000 gallons per machine.

The spray arms on the Butterworth Type DW are adjustable from 270 degrees down to zero. The machine will sweep a 45 degree area from the point which the arms are set. This allows the unit to be used in open tanks and in areas where a high buildup of solids might require some additional cleaning focus.
