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.
