Dehumidification

The highly efficient Ultra-Aire XT whole house ventilating 
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 XT's are controlled by 24 volt remote wired controls.  
A variety of controls are available for 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 replenish 
oxygen content in the building. The amount of fresh air ventilation 
can be regulated by a variety of dampers and controls.

Air Filtration

The Ultra-Aire XT includes air filtration to improve indoor air quality. 
A MERV-11 media filter is standard. An optional external  
filter box with a MERV-14 deep pleated 95% media filter is  
available for optimum air filtration and to reduce potentially  
harmful airborne particles.
