Dehumidification
The highly efficient Ultra-Aire XT150H 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 XT150H 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 Ultra-Aire XT150H includes air filtration to improve indoor air
quality. A MERV-11 media filter is standard. An optional external
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, a standard filter operates as a prefilter.
