The APV Cavitator


THE NEXT GENERATION IN MIXING AND HEATING TECHNOLOGY
SPX offers an innovative new next generation technology called the APV™ Cavitator. The patented technology offers breakthrough benefits for the heating of liquids without scale buildup and/or the mixing of liquids with other liquids, gases or solids at the microscopic level to improve product quality and functional performance. The breakthrough results are obtained by using the forces of cavitation in a controlled manner rather than typical impellers or blades to process materials. With the APV™ Cavitator, the mass transfer rate can be increased and results are obtained that far exceed those of any technology in the market today. The controlled cavitation process is being considered a paradigm shift in the mixing industry where process intensification, process acceleration and the replacement of batch processing with continuous processing are necessary to compete in a global economy.

The APV™ Cavitator can heat liquids in seconds, whether in batch or continuous systems. This heating can be done accurately and consistently by varying rpms through a temperature controller and variable frequency drive. There is no temperature gradient or hot or cold spots. The unit does not have a heat transfer surface at elevated temperature, so there is no scaling or fouling. The system is flameless and can be totally automated.

The APV™ Cavitator has an elegantly simple and robust design that is proven through years of commercial operation in the chemical, petroleum, and food industries. The robust stainless steel construction, easy to use control system, small footprint, and quiet operation make the APV™ Cavitator an unparalleled heating and mixing system.

Product Features:

  • Scale-free thermal processing of thick and viscous fluids
  • Fast processing

How The APV Cavitator Works

The heart of the technology is a specialized rotor with spinning action generates hydrodynamic cavitation within away from the metal surfaces. The cavitation is controlled, there is no damage.

As a liquid passes through the APV™ Cavitator, it is subjected controlled cavitation. Microscopic cavitation bubbles and as they collapse, shockwaves are given off into can emulsify and prevent scaling. During heating, temperature created uniformly throughout the entire liquid without transfer surfaces. There are no hot or cold spots.
