D. GAS BURNER ASSEMBLY
Gas-heated dryers are equipped with a
gas burner assembly consisting of four (4)
burner tubes, gas valve, HSI (Hot Surface
Ignition) ignitor, flame probe, sail switch,
and hi-limit thermostat. 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.
E. DRIVE MOTOR
The T.E.F.C. (Totally Enclosed, Fan-Cooled)
drive motor is located approximately in the right
front hand corner of the dryer. It sits on an
adjustable base so that the motor can be easily
adjusted to the left or right. The drive motor is
a 3 HP motor and operates on 208 to 460 volts,
50/60 Hz, 3-phase (3ø).
F. BLOWER MOTOR and IMPELLOR
(GAS and STEAM)
The impellor is shaft driven. The blower motor drives the shaft
on which the impellor is mounted. This enables the impellor to
run at a higher RPM, thereby producing a higher airflow (CFM).
