Description

RK and RKT are control dampers for rectangular ducts. They are available with blade tightness class 1 (RK) or 2 (RKT), tested according to EN 1751. They can be used as control dampers for air flow adjustment. RKT is also foreseen as a shut-off damper in case of lower tightness requirements. The dampers can be supplied in a manual version with adjustment handle or with preparation for attachment of an actuator. The maximum recommended duct pressure for operation is 1000 Pa.

Design

RK, RKT units are made with aluminium profile frame and multiple aluminium profile blades. The frame has 30 mm wide flanges for tight connection to the duct. The blades are from extruded aluminium. On RKT the blades are equipped by rubber gaskets reducing leakage in closed position. The blade axe are sitting in self lubricating bearings which are connected together by a cog gearing (for smaller sizes) or rod gearing (for larger sizes) for counter action positioning of the blades. The manual version has an adjustment handle with position arresting bolt. The version with actuator preparation has a shaft 12 mm x 12 mm.

Average The Room Is A Normal Residential Room, Office, Reception Area Or Similar, Where There Is Not Overly Crowded With People, Computer And Office Equipment.
Above Average There Are Factors That Contribute To Additional Heat Being Generated In The Room E.G. Strong Lighting, Overcrowding With People And Office Equipment, Conservatory Type Room, Or Flat Roofed Room.
High There Are Factors That Contribute To A High Heat Load In The Room. E.G. Commercial Cooking, Much Computer And Server Equipment, Switchgear, Temporary Building With Thin Walls And Flat Room, Plain Glass Conservatory.
