NEM Energy - Louver Dampers

NEM Energy designs and builds louver dampers in accordance with the plant-specific parameters and clients’ individual specifications, and the dampers are available in various designs, dimensions and shapes, with or without duct section (T-Box). Actuation can be manual, electrical, pneumatic or hydraulic type. The construction materials used depend on the operating temperature and pressure, abrasive or corrosive environment and other process operating conditions. Louver dampers can be built as single or double louver versions, and are designed with either internal or external insulation.

Depending on the operating conditions and the required degree of tightness, different seal arrangements are available. Double louver dampers or twin-blade lover dampers with seal air injected in-between both blade planes provide a hundred percent tight barrier against gas leakage.
