4.Steam Damper Air System Connections
This dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just in front of the electric service relay box.
a. Air Requirements
Compressed Air Supply | Air Pressure | |
|
|
|
Normal | 80 psi | 5.51 bar |
Minimum Supply | 70 psi | 4.82 bar |
Maximum Supply | 90 psi | 6.21 bar |
b.Air Connection
Air connection to system
c.No air regulator or filtration is provided with the dryer. External regulation/filtration of 80 psi (5.51 bar) must be provided. It is suggested that a filter/regulator/gauge (F/R/G) 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.
5.Steam Damper System Operation
The steam damper shown in Diagram 1 in the illustration on the next page, 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 2).
