Venturi devices known as instantaneous or silent heaters can be used to directly inject steam into the motive fluid to raise its temperature. This allows for fluids to be heated inline which is inherently a more efficient and quieter process than a using a traditional tank and sparger nozzle arrangement.

  • Single pass operation allows the motive fluid to be heated by up to 30 degC.

  • Passing the motive fluid through the heater multiples times allows heating of greater than 30 degC to be achieved.


  • The final fluid temperature is dependent on the operating pressure as the maximum fluid temperature has to be 20 degC less than the fluid saturation point to prevent flashing.

  • Multiple heaters of different sizes can be installed in parallel to provide control over a range of flowrates.
