What We Know About Building Ventilation

• Indoor air can be 2-5 times more polluted than outdoor air.  Learn More
• Outdoor air reduces indoor air pollution improving IAQ
• Low outdoor air ventilation rates result  in health risks to building occupants
• Higher outdoor air rates not  only improve occupant health, but also increase productivity - more is better!
• Conditioning outdoor air can represent 40% of an HVAC system's capacity 
• Everyone wants to keep energy costs low
• A primary cause of indoor moisture problems is moisture laden outdoor air entering the building

Why Airxchange Energy Recovery Wheels

• Patented wheel technology that reduces energy requirements for conditioning outdoor air by 70%
• Removal of moisture from outdoor air in the summer and addition of  moisture in the winter to help keep buildings in the ideal humidity range
• Energy recovery ventilation provides performance efficiencies unmatched by any other technology in the industry
• All the health and productivity benefits of outdoor air ventilation without  the drawbacks of excessive energy consumption and moisture problems

How Energy Recovery Wheels Work

• Airxchange energy recovery wheels rotate between the incoming outdoor airstream and the building exhaust airstream.
• As the wheel rotates, it transfers a percentage of the heat and moisture differential from one airstream to the other
• Consequently, the outdoor air is 'pre-conditioned' significantly reducing the capacity and energy needed from the mechanical HVAC system
