Energy Recovery Ventilators With Cooling and Heating

Greenheck manufactures four product lines, ERCH, ERT,VersiVent and APEX that combine the benefit 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.

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.

Overview

  • 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

    Designed with forward curved fans, model ERCH handles applications up to 1.5 in. wg. external static pressure. Compact and economical, model ERCH is an ideal dedicated outdoor air handling unit.

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

    Heating Options: Hot Water, Electric, Indirect Gas


  • 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.


  • Model Ver (VersiVent)

    VersiVent model offers the next level of custom features in a standardized product. There is flexibility in choosing the type of heating, cooling and wrap around pipe options, 2 inch double wall housing, high efficiency centrifugal plenum supply fan, and increased pressure capabilities to 3 inches w.g. on supply. The size and configuration of each VersiVent is based on performance and options selected. The optional packaged dx cooling system from Greenheck is charged with environmentally friendly R410a refrigerant. CFM performance range from 2,000 - 10,000.

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

    Heating Options: Hot Water, Indirect Gas, 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.
