How Your Humidier Works
Your Skuttle Under Duct Humidier uses the same principle of evaporation
that you see in nature: a warm breeze passing over an expanse of water
will evaporate the water and raise the relative humidity, just as it does after
a summer shower.
Model 55
When you home is drier than your selected humidity setting, the
humidistat (your humidier’s sensor and control device) turns on
the unit’s internal low-voltage solenoid, allowing water to ow
across the evaporator pad. As the furnace blower forces warm,
dry air across the humidier’s water-soaked pad, some of the
water is evaporated. The newly-moistened air is then circulated
throughout your home by the heating system.
Model 86
When your home is drier than your selected humidity setting, the
humidistat (your humidier’s sensor and control device) turns on
the unit’s low-voltage drum motor. The motor rotates a polyurethane
foam evaporator pad which lifts water out of the water pan and
into the dry air stream. The newly-moistened air is then circulated
throughout your home by the heating system.
It’s important to note that water evaporated from the humidier leaves
behind all the impurities (calcium, iron, lime, bacteria, etc.) that were
originally contained in the water. As a result, these impurities are not
dispersed throughout your home, which keeps your living environment
cleaner and your family safer from harmful contaminants.
