5. Steam Damper System Operation
The steam damper, as shown in the
illustration, 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.
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.
6. 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.
