SCHOFIELD, Wis. — Energy Core Ventilators (ECV) from Greenheck transfer both sensible (heat) and latent (moisture) energy between the exhaust and supply airstreams without the airstreams mixing. The energy recovery core separates the supply and exhaust air, ensuring only fresh air is introduced into the indoor space while providing superior heat transfer and moisture permeability.

Model ECV-PM, the latest addition to Greenheck’s ECV line, features an AHRI 1060-certified polymer membrane energy recovery core manufactured from corrugated aluminum sheets used to separate the polymer membrane layers. The new polymer membrane energy core allows for low air-side pressure differentials, increasing ECV airflow capacity by 15% per housing size versus a fiber membrane. The polymer and aluminum material provides increased thermal effectiveness and allows for easy washable maintenance. Designed for indoor and outdoor mounting for commercial applications requiring 500-3,750 cfm of ventilation air and up to 1 in. wg, the ECV-PM is ideal for office buildings, schools, hospitals, churches, dormitories, and nursing homes.
