Flap Diverters allow the user to control the flow of TEG to the HRSG and to positively isolate the HRSG so that routine maintenance can be carried out during normal operating periods.Each Flap Diverter is custom designed to suit the exact operational requirements in accordance with the relevant specification.

Flap Diverters form an integral part of numerous land based diesel and gas turbine CHP plants and offshore HRSG installations. Actuation can be electric, electro-hydraulic or pneumatic, with modulation and failsafe facilities available as an option. Sealing efficiencies range from 99% to 100% with a seal air fan.
