Dedicated Outside Air Models with Energy Recovery (ERV)


The DES/DX with ERV includes an energy recovery wheel to exchange enthalpy between the exhaust and the outside air prior to the pre-cooling coil.  Incorporating the ERV into the DES/DX system tempers the outside air, eliminating significant compressor tonnage and thereby reducing the overall energy consumption considerably. Make-up air is then efficiently dehumidified prior to entering the space. 

Outside air is cooled and dehumidified through one or more refrigeration circuits prior to entering the desiccant wheel.  The desiccant wheel provides additional dehumidification while returning the air temperature back to space neutral conditions (but much lower %RH).  Waste condenser heat is used to reactivate the desiccant wheel.

  • Ultra energy efficienct process for outside air treatment while achieving low supply air dewpoints.
  • Standard models available from 2000-10000cfm.
  • Winter heating and post-cooling options available.
