ThermoFlo™ Model 464 Tubular RF System

For Continuous Heating, Cooking and Sterilizing of Fluids

The ThermoFlo™ system provides rapid and uniform heating of material transported through a tube passing through a high frequency field. Radio frequency waves create heat within the product stream itself rather than by conduction from hot surfaces.


  • Improved product quality and productivity through controlled temperature, short time treatment of the product stream.
  • Eliminates flavor degradation and denaturing caused by over-temperature product exposure.
  • Reduces the heating time to achieve centerpoint kills in large particulates in the product stream.
  • Energy savings through the system's highly efficient process heating concept.


  • Heating time is greatly reduced from that of conventional methods.
  • High volume heating is achieved with a relatively small processing system requiring little floor space.
  • Equipment clean-up and sterilization is simplified.

  • The ThermoFlo™ system processes liquids, emulsions and solid-liquid mixtures.
  • For aseptic processing, cooking, pasteurization, and sterilization of rice, soups, puddings, fruit, sauces, baby foods, purees, eggs, and other applications.


  • Use of the ThermoFlo™ heating system permits rapid heating of liquids, including those containing large particles.
  • The system processes free-flowing or pumped fluids at normal or elevated pressures.
  • Only a tube constructed of inert material is in contact with the product.
  • The energy is "instant-on".
  • The ThermoFlo™ system meets OSHA Safety Standards and FCC regulations.
