Custom-Made Coiled Rod Turbulators for Every Application

How Coiled Rod or Spring Turbulators Work

Turbulators break-up the laminar flow of fluids or gasses inside the tubes or flue passes of heat exchange equipment to promote greater contact with the tube wall resulting in more even heat distribution and improvement in heat transfer coefficients. They are custom-made for every application and fabricated in such a way that the coil OD closely matches the tube ID, providing the greatest measure of conductive heat transfer. Turbulators can help to extend equipment life by eliminating hot and cool spots that cause thermal stress and can also reduce the formation of soot by improving combustion characteristics to lower maintenance costs.

Like the Angular (“Brock”) Turbulator, the Coiled Rod turbulator is normally used in gaseous applications.

  • Firetube Boilers
  • Radiant Heaters


Coiled Rod Turbulators are shipped ready to install and require minimal boiler/burner modifications. The average installation takes one to four hours. In most cases there’s no downtime or loss of heat or steam pressure.


If we do not meet our agreed upon specifications, we will replace your turbulators for free!


Turbulators are custom made and available in a variety of configurations to fit most tube sizes and many types of heat exchange equipment.
