Dampers

Pressure relief dampers for high opening pressures, with switching function type KL-EM

In a great variety of different applications within HVAC systems pressure relief dampers manufactured by Krantz are used to limit the pressure and control it, respectively. Typical applications include the protection of ductwork from inadmissible high loading caused by positive pressure or negative pressure, positive pressure ventilation of staircases, or setting a defined pressure drop between adjacent rooms.

Features:

The Pressure Relief Damper Type KL-EM features a switching function. Independent of the range of volume flow of the outlet flow the damper blade gets fully opened when the opening pressure is exceeded. When the pressure in the ductwork falls below the opening pressure after the malfunction has been remedied, the damper normally remains open. In this state of operation the damper type KL-EM must be closed manually, whereas it closes automatically when the flow is interrupted, e. g. by disabling of the fan. Despite its smaller outside dimensions type KL-EM is capable of removing flows at higher range of volume flow as compared with type KL-E.
