Steam Damper System Operation
The steam damper, as shown in the illustration (above right),
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 basket (tumbler),
allowing a rapid cool down.
Steam Damper Air Piston (Flow Control)
Operation Adjustment
Damper operation was tested and adjusted prior to shipping
at 80 psi (5.51 bar). If damper air adjustment is necessary,
locate the flow control valve and make the necessary
adjustments as noted below.
Diagram 1
shows the damper in the heating (open) mode,
allowing heat into the basket (tumbler).
Diagram 2
shows the damper in the cool down (closed)
mode, pulling ambient air directly into the basket (tumbler)
without passing through the coils.
Note
With the dryer off or with no air supply, the steam
damper is in cool down mode as shown in
Diagram 2.
