Learn about the Alpha Aire 200–500 CFM DOAS unit and how you can benefit from this unique equipment.

1. Alpha Aire
Dedicated Outdoor Air System, VAV,
Air-Source Heat Pump with Energy Recovery
Horizontal
Vertical

2. Indoor Air Quality – IAQ Made Simple
• Alpha Aire is designed to
provide a low CFM “one stop
shop” product. All indoor
installation only one product to
source, easy to install, easy to
maintain makes this a great
solution to IAQ challenges.
• Packaged Air Source Heat
Pump with Energy Recovery
Ventilation System
• Install within hours not days
• Compressor can be changed
without evacuating, brazing or
charging.
• Dual Energy Recovery
Ø Aluminum Plate Heat
Exchanger
Ø Total Energy Recovery Wheel
• Higher* ISMRE 11.11 &
ISCOP 8.02 than any Similar
Product Currently on the
Market
1. Integrated Seasonal Moisture
Removal Efficiency
2. Integrated Seasonal Coefficient of
Performance
* More than 2X as required by ASHRAE 90.1 – 2016

3. Applications
Alpha Aire is designed to fit any application large or small. If
the requirement is larger than 500 CFM, then use multiple
units strategically placed indoors. The total installed cost will
most likely be less than one large split system, or an RTU with
a roof curb and traditional duct work running to various parts
of the building. Quiet operation allows you to place these
above occupied space to deliver fresh air where you need it,
when you need it.
