Reversing Relay Panel

Lifting the control door will reveal the reversing relay box. Located on the back of the relay box is the reversing relay panel. Included on this panel is a 4-position terminal block, blower overload, blower contactor, reversing contactor, 24 VAC transformer, fuse or circuit breaker, ground lug, and possibly an arc suppressor board.

Gas Burner Assembly

Gas heated dryers are equipped with a gas burner assembly consisting of 3 burner tubes, a gas valve, an ignitor, a flame sensor, a sail switch, a hi-limit thermostat, and an ignition control module. The inlet piping enters through the rear of the dryer on the left-hand side (viewing from the front) and runs to the front of the dryer where the gas valve is located.

Steam Coil and Damper System

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 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.

Steam Coil pH Level

NOTE: The normal pH level for copper type steam coils must be maintained between a value of 8.5 to 9.5. For steel type steam coils the pH level must be maintained between a value of 9.5 to 10.5. These limits are set to limit the acid attack of the steam coils.

IMPORTANT: Coil failure due to improper pH level will void the warranty.

Steam Damper Actuator System

The steam damper actuator system consists of a hinged damper plate, pneumatic piston, and a 24 volt solenoid valve with a needle valve to control the speed of the piston actuation.

Drive Motor

The T.E.F.C. drive motor is located in the rear right corner (viewing from front) behind the front panel of the dryer. It sits on an adjustable base so the motor can be easily adjusted to the left or right, up or down, forward or backward.
