Inlet Damper Systems

Solutions for Moisture-Rich and Cold Environments

Moisture-rich environments can cause unnecessary corrosion and erosion to internal components on Gas Turbine (GT) inlet and compressor components. Blades, vanes, and other components can see moisture pitting and staining leading to decreased efficiency. Another problem in cold environments is that the HRSG cannot retain heat from escaping without closing off the inlet system.

With that in mind, Braden designed its Inlet Damper Systems to deliver conditioned air between the filter house and gas turbine for typical use when the GT is shut down or is on turning gear for an extended period of time. Our system is built to the following codes: ASME, ASTM, AWS, NFPA, NRTL cert., NEC, IEC, and NEMA.

Inlet Damper Door





Used primarily to seal off the GT internals from the outside environment. Natural air convection from stack draft effect causes air to continue to flow through the inlet, GT, and exhaust duct when shut down or on turning gear.

Technical Design:

  • Minimal leakage design
  • Stainless steel or carbon steel construction
  • 30-year design life

Dehumidifier Skid

Used in conjunction with the inlet damper door to provide dehumidified air to the GT internals (a heater skid can also be provided).

Technical Design:

  • Connected to inlet system by interconnecting piping
  • PLC-controlled safety system to prevent fire, component damage, and if there is any blockage in the system
  • 30-year design life
