The dryer is equipped with a pneumatically operated heat reclaimer damper, which when opened, will recirculate
approximately fifteen percent (15%) of the dryer’s exhaust air.
The heat reclaimer damper is closed until ignition of flame has been established. Then, the damper piston is
actuated, opening the dampers recirculating fifteen percent (15%) of the exhaust air back over the gas burner
and into the tumbler (basket). The damper remains open for the rest of the drying cycle. On cool down, the
damper closes, exhausting
ALL
of the 13,000 cfm which ensures a fast cool down of the load.
4. TIGHTEN TOP HEAT RECLAIMER NUTS DOWN
ONTO THE BOTTOM HEAT RECLAIMER NUTS.
EXAMPLE
: IF THE DESIRED PISTON STROKE IS
TWO (2) INCHES (5.1 CM), THAN THE
DISTANCE "X" IN THE ILLUSTRATION
MUST BE
TWO (2) INCHES (5.1 CM)
.
3. ADJUST THE BOTTOM HEAT RECLAIMER NUTS
DOWN TO THEIR DESIRED POSITION WHICH
WILL GIVE THE PROPER PISTON STROKE.
2. LOOSEN HEAT RECLAIMER ADJUSTMENT NUTS
ON
ALL
FOUR (4) CORNERS OF THE HEAT
RECLAIMER PISTON.
