HUMIDAIRE UNIT OPERATION
HOW DOES A HUMIDAIRE UNIT WORK?
Air is drawn into the Humidaire Unit and around a burner head that heats the air. This
hot air enters a stainless steel water spray chamber. In the spray chamber, the hot air is
scrubbed, cooled, and humidified by a large volume of water circulated through stainless
spray nozzles by a 7.5 HP pump.
Zig-zag mist eliminator baffles at the outlet of the spray chamber allow humid air to
leave while retaining water droplets. An external fan (not included) transfers the warm
humid air to the place in the gin where it is applied to the cotton. As the water is
evaporated from the tank, a float valve refills the tank.
Adjustment of the absolute humidity of air from the Humidaire Unit controls the amount
of moisture applied to the lint. Absolute humidity is controlled by setting the temperature
of air and water on the touch screen or optional Moisture Mirror II. The new Humidaire
Speedometer feature will show the operator how much moist air output results from the
temperature settings. Briefly stated, the closer these two temperatures are together, the
higher the absolute humidity.
The burner fuel valve is automatically regulated to maintain the air temperature selected.
At the same time, a stainless steel butterfly valve on the water system is regulated to
maintain the water temperature selected by controlling the volume of water exposed to
the heat through the water spray nozzles.
HOW DO I TURN IT ON?
Refer to the
MOISTURE MIRROR II
section of manual for more information on
operating the Humidaire Unit remotely using the optional Moisture Mirror II color touch
panel. The instructions below are for using the color touch panel mounted in the upper
cabinet door on the unit.
Touch the button on the left side of the screen marked with an “I” to turn on the
Humidaire burner. This provides warm dry air. Touch the button on the right side of the
screen marked with an “I” to enable the water pump. This will provide warm moist air
when cotton enters the system. The button marked with “0” is the corresponding OFF
button for each function.
If there is a problem detected by the Humidaire Unit control system, it will notify you on
the touch screen with a brief description that includes a diagnostic number. This number
will be helpful to the technician that offers assistance if you call the factory. Many
