Air connection to system
c.Air Regulation
No air regulation or filtration is provided with the dryer. External regulation and filtration of 0.75 cfh at 80 psi (0.02 cmh at 5.51 bar) must be provided. It is suggested that a regulator or filter gauge arrangement be added to the compressed air line just before the dryer connection. This is necessary to ensure that correct and clean air pressure is achieved.
4.Steam Damper System Operation
The steam damper, as shown in the illustration 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 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 damper is in the cool down mode as shown in Diagram 2.
