Air-to-Air Exchangers

Heat Wheels design units are the most energy efficient and by far the most popular technology used worldwide and by Annexair, too. Capacities vary from 2,000 CFM up to 100,000 CFM.

Fixed Plates design is our 2nd most popular technology. Capacities vary from 2,000 CFM to 80,000 CFM.  

Dual Wheels design is our 3rd popular design. Dual Wheel units include an Enthalpy and Sensible wheel combination for dehumidification purposes. Capacities vary from 2000 CFM up to 30,000 CFM.

Wheel-Plate design is also popular, very similar to the Dual Wheels design. It includes an Enthalpy wheel and a Sensible plate combination for superior efficiency in dehumidification mode. Capacities vary from 2,000 CFM up to 10,000 CFM
