Everything You Need to Know About Diverter Dampers

Posted: August 30, 2022 | Category: Industrial Dampers

If you utilize a system that requires the flow of gas to be diverted between different outlets, you likely need a high-quality diverter damper to ensure lasting safety and reliability. As a leading provider of industrial dampers and other solutions, the team at Flextech Industries knows how important it is to choose the right product for your precise needs. That is why we have outlined everything you need to know about diverter dampers to ensure that you have the information you need to make an informed decision.

How do Diverter Dampers Work?

The purpose of diverter dampers is to redirect the flow of gases from one outlet to another. This allows them to be used to efficiently recover heat, generate steam, and ventilate gases. The low number of moving parts in diverter dampers allows them to last longer than many other types of dampers. Diverter dampers are also inexpensive to install and enhance energy efficiency to reduce ongoing operating costs, making them a popular choice for various applications.

What Types of Diverter Dampers are Available?

While all diverter dampers are designed to perform similar functions and accomplish the same goal, there are two different types available to ensure that gas exits a system at the intended outlet. The two main types of diverter dampers available include:

T-Diverter Dampers

T-diverter dampers are ideal for systems that need their gas flow to be diverted to a new direction. These dampers allow certain sections of a system to be isolated and bypassed, allowing the gas flow to be modulated. There are 4 different t-diverter damper seal designs, each suited to different applications:

  • Swing-Through Seal: Ideal for dirty applications where tight shut-off is not required.
  • Step Seat: Suitable for relatively clean gas applications.
  • Tadpole Seal: Ideal for clean applications when tighter leakage rates are required.
  • Step Seat with Perimeter Seal: Designed for clean applications, featuring an elastomeric perimeter seal on the blade.

Flap Diverter Dampers

Flap-diverter dampers are highly effective for systems with excessively high temperatures and heat production, such as steam generators, heat recovery systems, and turbine exhausts. These dampers use a flap to change the outlet that gas is pushed through in an application. Flap-diverter dampers are also ideal for systems without a clean flow of gas moving through them, as erosive materials do not contact the moving blade. This means that they can last for a long time in systems that contain particulates.
