Abstract

An industrial roll-up damper that contains all welded internal attachment components and during normal operation, all moving parts are isolated from the duct flow. In one particular embodiment, the roll-up damper is designed to be used as a gas turbine inlet shutoff damper in conjunction with an inlet dehumidification system. The roll-up damper comprises a single sheet membrane stored on a roll-up spool and an inflatable rubber seal which when applied to gas turbines, functions to isolate the turbine inlet, thereby allowing dehumidified air to be introduced into the intake of the turbines while the engine is not in operation.
