How Your Humidifier Works
Your Skuttle Under Duct Humidifier 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 humidifier’s sensor and control device) turns on
the unit’s internal low-voltage solenoid, allowing water to flow
across the evaporator pad. As the furnace blower forces warm,
dry air across the humidifier’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 humidifier’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 humidifier 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.
