Diverter Dampers

Diverter Dampers are tight shut-off devices used to redirect hot gas flow from one outlet to another, and are commonly used in heat recovery steam generator (HRSG) exhaust stack applications. Our Effox-Flextor brand Diverter Damper can be configured in a low-leak or zero-leak design, and a toggle-type or pivot style diverter damper for HRSG, waste heat recovery, natural gas turbine and other systems that require diversion of the gas stream.

Our Diverter Damper units are available with simple blades, structural blades, thermally compensating blades and profiled blades, each constructed for optimal performance. Applying decades of experience, we are able to deliver custom designed solutions configured for your specific application requirements, providing efficient operations for a long service life.
