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 returned to the air stream, 
resulting in an overall temperature increase of the air leaving the unit.

The Ultra-Aire 100V is controlled by 24 volt remote wired controls. A 
variety of controls are available suitable to various applications.

Fresh Air Ventilation 

Optional fresh outdoor air may be ducted to the unit via a six inch 
round duct. This provides fresh air to dilute pollutants and maintain 
high oxygen content in the air. The amount of fresh air ventilation can 
be regulated by a variety of dampers and controls.

Air Filtration

The UA-100V includes air filtration to improve indoor air quality. A 
MERV-11 media filter is standard. An optional MERV-14 deep pleated 
95% media filter is available for optimum air filtration and to reduce 
potentially harmful airborne particles. If the optional filter is chosen, 
the standard filter operates as a prefilter.
