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 Dampers 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.
