How it works
◆ In Heat Exchanger (Shell and Tube Type)
The transducers of USP are welded on tube sheet of heat exchanger all tubes connected.
◆ In Heat Exchanger (Shell and Tube Type)
The transducers of USP are welded on tube sheet of heat exchanger all tubes connected.
Once USP runs, acoustic vibration is transferred to whole tube surface in heat exchanger through the transducers welded on tube sheet. Then whole tube surface turn into a wide acoustic radiation surface having radiation force and the acoustic radiation force makes acoustic streaming into the fluid which flows in whole tubes. As this acoustic streaming acts vertically against flow direction of fluid (laminar flow), particles motion in the fluid becomes significantly active and then convection and turbulent flow are generated in the flow in tube. These two key kinetic energies given continuously by USP, acoustic vibration on the tube surface and acoustic streaming in the fluid, can prevent or mitigate fouling deposit on tube
surface and fouling forming in the fluid and also can dissolve a preformed fouling. This improves heat circulation in the facilities and so enhances the efficiency of heat transmission.

◆ In Boiler
The transducers of USP are directly welded on shell body of boiler.
The transducers of USP are directly welded on shell body of boiler.
Once USP runs, acoustic vibration is transferred to whole shell body of boiler from the transducers welded spot. Then whole shell body of boiler turn into a wide acoustic radiation surface having radiation force.
The acoustic radiation force makes acoustic streaming into the fluid. and makes cavitation near the transducer welded spot.
The acoustic radiation force makes acoustic streaming into the fluid. and makes cavitation near the transducer welded spot.
These three key kinetic energies given continuously by USP, acoustic vibration on the tube surface and acoustic streaming in the fluid and cavitation near the transducer welded spot, can prevent or mitigate fouling/scale deposit on shell inside and tube outside surface and fouling forming in the fluid and also can remove a preformed fouling/scale on shell inside surface. This improves heat circulation in the facilities and so enhances the efficiency of heat transmission.
