Dehumidification
The highly efficient Ultra-Aire 100V dehumidifier utilizes refrigeration
to cool the incoming air stream below its dew point. This cooled and
drier air is used to pre-cool the incoming air stream resulting in a
significant increase in overall efficiency. After the pre-cooling stage,
the processed air is reheated by passing through the condenser coil.
The heat removed by the evaporator coil is ret
