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

Indoor Air Quality – IAQ Made Simple • Alpha Aire is designed to • Dual Energy Recovery Ø provide a low CFM “one stop Aluminum Plate Heat Exchanger shop” product. All indoor Ø Total Energy Recovery Wheel installation only one product to • Higher * ISMRE 11.1 1 & source, easy to install, easy to ISCOP 8.0 2 than any Similar maintain makes this a great Product Currently on the solution to IAQ challenges. Market • Packaged Air Source Heat 1. Integrated Seasonal Moisture Pump with Energy Recovery Removal Efficiency Ventilation System 2. Integrated Seasonal Coefficient of • Install within hours not days Performance • Compressor can be changed * More than 2X as required by ASHRAE 90.1 – 2016 without evacuating, brazing or charging.

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.
