Airxchange Technology : Improve System Efficiency

Improve HVAC System Efficiency

Increase Cooling Efficiency

  • Per Guideline V calculations, a typical Airxchange wheel preconditions outdoor air at efficiencies equivalent to 60 EER leading to 40% system efficiency improvement.
  • Generally equivalent performance is available for air handling systems.
  • Airxchange wheels provide up to 4 tons of cooling per 1000 cfm of outdoor air

Increase Heating Efficiency

  • The wheel has similar impact on the heating system reducing outdoor air heating costs by 70-80%
  • Airxchange wheels provide up to 90 mbh of heating per 1000 cfm of outdoor air
