Directed Spray Mast

Technology Marketing Summary

Engineers at the Savannah River National Laboratory (SRNL) have developed a remotely-operated tank cleaning device for precise, high-pressure spray for use in limited access areas.  The device offers features unavailable in tank cleaning technologies currently on the market, providing for better, faster and cost-effective tank cleaning.


The directed spray mast was originally conceived to eliminate the inherent dangers involved with sending workers into storage or process tanks during cleaning operations.  The directed spray mast was designed to provide more precise cleaning of problem build-up areas within a tank versus the more global cleaning approach of existing technologies.

The design features of the directed spray mast provides for effective cleaning up to 20 feet away from the access point at pressures as high as 3,000 psi.  Tank entry for the directed spray mast requires an access port of only three inches in diameter.  In addition, this spray device has been effective in cleaning either hard or soft sludge buildup while requiring less water and electricity to accomplish the task.

  • cleans with high precision
  • operates at extremely high pressures
  • fits through small tank-entry ports
  • requires less water
  • reduces electricity
Applications and Industries

This technology can be applied to any industry requiring a precise, high-pressure spray cleaning device with a limited access area.  Some prospective areas of use would include slurry tanks for food processing; fermentation tanks for beverage manufacturing; paint and textile processing vessels; batch process tanks for chemical manufacturing; and hazardous waste storage tanks. This technology has been tested and deployed in the field for effective cleaning of evaporator tanks at the Savannah River Site (SRS).
