Rectangular damper
The control damper is used to regulate the air pressure and volume flow with external control options, depending on the control/regulation conditions. SIA BIC rectangular control damper blades have a profiled construction with smooth surfaces to avoid cold transfer and to prevent the accumulation of dirt on the blades. The amount of blades depends on the size of the brew. The recommended torque for damper`s motors is calculated based on the cross-sectional area of the valve.
