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
ExchangerØ 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
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.

North Kentucky UniversityBased on the dimensions of this unit, it was able to fit into the small space they had available for the new HVAC system. This unit also met the all-indoor, packaged, 100% OA that was required per standards. As soon as the engineer saw what we had to offer, they did not hesitate to place 9 of our units throughout the building. Being so pleased with the performance, NKU has ordered 9 more units for another dormitory.
