Steam Damper System Operation

The opposite side of each linkage will then be fastened to the appropriate damper assembly. There are 5 holes on each damper flange. The best adjustment is usually found in the center hole. However, this may not hold true on every damper assembly due to manufacturing tolerances. The linkage is then fastened to the damper flange in the same manner as step 2. Refer to figure 1. The linkage support assembly should be turned CCW until the damper assemblies seat securely against the steam coils and the setscrew is to be tightened securely.

The lever arm assembly should then be positioned on the center bar on the front of the steam damper assembly. With the damper assemblies seating securely against the steam coils, the lever arm should be positioned between 8:00 and 9:00. These connections are all shown in figure 2.

Once the connections are all made, turn the activating bracket assembly CW. The entire assembly should turn freely without binding or excessive force. The bottom of the damper assemblies should both meet approximately in the center of the plenum. The damper assemblies should meet almost flush. Refer to figure 3. If the dampers resist closing or if they do not meet almost flush, it may be necessary to move either one or both of the linkages up or down on the damper flange depending on the adjustment required.

Once proper adjustment has been accomplished, power up the dryer and activate a cycle. Observe the closing of the damper assembly. Again the dampers must meet. If they do not it may be necessary to readjust again. The misalignment may also be due to loose setscrews. If proper adjustment cannot be obtained, contact the technical support department at ADC for assistance.

The steam damper, as shown below, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the tumbler, allowing a rapid cool down.

Diagram 1 shows the damper in the heating (open) mode, allowing heat into the tumbler.

Diagram 2 shows the damper in the cool down (closed) mode, pulling ambient air directly into the tumbler without passing through the coils.

Note

!With the dryer off or with no air supply, the damper is in the cool down mode as shown in Diagram 2.
