Turbulator – Various Materials to Increase Heat Transfer Efficiency

Turbulator is an ideal device to efficiently optimize the heat transfer. It is formed by different metallic wire, such as carbon steel, stainless steel, chrome-nickel alloy, copper, brass and aluminum.

The device is inserted into the tube side of industrial boiler, shell & tube heat transfer and other types of heat transfer equipment. It is designed to keep turbulent flow and it helps to improve the heat transfer efficiency by increasing surface area of substance flow.

They are widely used in air-cooled heat transfer and cooling towers in process, engineering, construction, petrochemical, refinery, power and gas compression applications, etc.

Turbulator helps to increase heat transfer efficiency and save costs.

There are five types turbulator:

  • Spring turbulator.
  • Soldered turbulator.
  • Twisted turbulator.
  • Hollow rod turbulator.
  • Flexible turbulator.

Features

  • Reduce uneven distribution.
  • Increase in flow velocity.
  • Corrosion resistance.
  • Decontamination.
  • Easy fabrication.
  • Easily installed.
  • Elastic force.
  • Lightweight.
  • Flexible.
  • Multiple types.
  • Customizable specifications.

Classical applications

  • Flexible turbulator is widely used in heat sinks, falling film evaporators and liquid cooled motors and static mixers.
  • Twisted turbulator is very suitable for refinery transfer because its twisted appearance can offer a low pressure drop and oil can pass easily.
  • Soldered turbulator is welded inside the tube of heat transfer. It offers an extended heat transfer surface and allows the manufacture of lightweight, strong compact coolers.
  • Spring turbulator is containing resilience and flexibility. It is used on horizontal heat transfer.
  • Hollow rod turbulator is especially useful when the liquid in the tube is very viscous and also where the viscosity varies greatly with temperature. Liquid near the tube wall develops a very high viscosity and forms a tunnel through which the hotter lower viscosity liquid passes through.
