ERV with Cooling & Heating

Dedicated outdoor air system (DOAS) incorporates a dedicated unit to supply cooled, dehumidified outside air to the building in the summer and heated outside air in the winter. Combining the benefits of the total energy wheel with supplemental heating and cooling. Fresh outdoor air is preconditioned by the enthalpy wheel, recovering up to 80% of the energy from the exhaust air, while the coil section further conditions the outdoor air to the desired conditions.

ERV with Cooling & Heating


  • Model APEX

    Model APEX

    Doubles the airflow capacity of the ERCH & ERT to 20,000 cfm providing convenient centralized air distribution. This semi-custom energy recovery rooftop ventilator with optional heating and cooling is available at a fraction of the price of the typical custom ventilators in this airflow range. Automatically generated submittals and an 8-week leadtime also make the APEX more attractive than a custom ventilator.

    Cooling options: Chilled Water, Direct Expansion (DX)

    Heating options: Hot Water, Electric

  • Model ERCH

    Model ERCH

    The model ERCH combines the benefits of energy recovery and many combinations of supplemental heating and cooling. This product is specifically designed to process 100% outdoor air to desired supply conditions. Four housing sizes provide air flow capacities from 1,000 CFM to 10,000 CFM with external static pressures up to 1.75 in. wg.

    Cooling Options: Chilled Water, Evaporative Cooling, Direct Expansion (DX) – split system or integral condensing

    Heating Options: Hot Water, Electric, Indirect Gas, Heat Pump

  • Model ERT

    Model ERT

    To expand the cooling and heating capabilities of the energy recovery wheel, a variety of tempering options are available. The coil section accommodates a cooling coil, a heating coil, or both. A wrap around heat pipe is available for providing space neutral air with the lowest operating cost.

    Cooling options: Chilled Water, Direct Expansion (DX)

    Heating options: Hot Water, Electric.

  • ARI Certification

    To guarantee your customers are getting the performance they request, check for ARI Certification. ARI Certified products are tested for energy transfer effectiveness (sensible, latent, and total), cross leakage, and pressure drop. If a manufacturer states that their products are tested "in accordance with" ARI Standards that DOES NOT mean they are certified. To be certified, products must be tested by ARI and have annual check tests.

  • Psychometric Chart

    A psychometric chart is a design tool to graph a building's HVAC thermodynamic air conditions and processes. Properties displayed on a chart include dry-bulb temperatures, wet-bulb temperatures, dew point temperatures, relative humidity, humidity ratio, specific volume, and enthalpy. A link is provided to a downloadable software program that allows the user to electronically plot conditions on a psychrometric chart. This program version permits the user to enter state points and graph the air conditioning process, while also calculating additional air properties.
