Pre-engineered rooftop unit features a total enthalpy wheel that rotates between two airstreams while transferring both sensible (heat) and latent (moisture) energy. Ideal for applications requiring high percentages of outdoor air, the enthalpy wheel offers up to 80% total effectiveness significantly reducing the heating and cooling capacity requirements for lower operating costs. Heating and cooling options are then provided downstream of the enthalpy wheel to provide additional tempering and dehumidification.

Airflow Range: 500 - 18,000 cfm
