Dehumidification
The Ultra-Aire SD12 is a split system dehumidifier that removes over
180 pints of water a day while adding no sensible heat load to the
living space. The dehumidifying unit is located inside the house and
the condensing coil is located outside. The two-piece design allows
the sensible heat load generated from dehumidifying the house to be
released in the outside condensing unit, thus eliminating additional
cooling load and reducing air conditioner run time.
Sensible Cooling
The Ultra-Aire SD12 provides approximately 1/3 ton sensible
cooling to the living space, allowing for first stage cooling and
moisture removal. The HVAC system can be used as a second stage
and be thermostatically set to a higher temperature to provide
additional cooling if needed. By eliminating the HVAC system's need
to control latent load, the Ultra-Aire SD12 allows the system to work
more efficiently.

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 SD12 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.
