Energy Recovery Wheel
What We Know About Building Ventilation:-
1. Indoor air can be 2-5 times more polluted than outdoor air. Click to:> Learn More
2.Outdoor air reduces indoor air pollution improving IAQ
3.Low outdoor air ventilation rates result in health risks to building occupants
4.Higher outdoor air rates not only improve occupant health, but also increase productivity – more is better!
5.Conditioning outdoor air can represent 40% of an HVAC system’s capacity
6.Everyone wants to keep energy costs low
7.A primary cause of indoor moisture problems is moisture laden outdoor air entering the building

Why Air Exchange Energy Recovery Wheels
1.A very good wheel technology reduces energy requirements for conditioning outdoor air by 70%
2.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
3.Energy recovery ventilation provides performance efficiencies unmatched by any other technology in the industry
4.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
1.Energy recovery wheels rotate between the incoming outdoor airstream and the building exhaust airstream.
2.As the wheel rotates, it transfers a percentage of the heat and moisture differential from one airstream to the other
3.Consequently, the outdoor air is ‘pre-conditioned’ significantly reducing the capacity and energy needed from the mechanical HVAC system
