D. STEAM COIL SYSTEM OPERATION

General Overview

The steam coil is constantly charged thereby eliminating repeated expansion and contraction and also provide instant heating to start the drying process. The steam damper, located on top of the steam coil, is the only temperature controlling device in this system. When the steam damper is open, ambient air is drawn through the coil providing heat to the dryer. When the steam damper is closed, ambient air is drawn directly into the basket (tumbler), bypassing the coil, allowing a rapid cool down.

NOTE: With the dryer off or no air supply to the damper piston, the damper is in the “Cool Down” mode...the coil is constantly charged.
