Heat and Moisture Exchangers

An HME may be considered when a building needs continuous ventilation while limiting the energy penalty associated with exhausting conditioned air. Applications can include homes, offices, commercial spaces, industrial facilities, and dedicated fresh-air systems. The appropriate configuration depends on airflow requirements, installation conditions, indoor air quality objectives, and the characteristics of the exhaust air.

An HME generally describes a heat and moisture exchange component or device, while an ERV is a complete energy recovery ventilation system that moves and exchanges air. BPE ERV and energy recovery module products combine counter-flow heat exchange with fans, filters, controls, or installation features depending on the configuration.

These systems can support residential homes, multifamily buildings, offices, light commercial spaces, industrial facilities, machine shops, and dedicated ventilation applications. Product information also identifies use in fresh make-up air systems, HVAC retrofits, new installations, and high-performance building projects such as Energy Star, Passive House, and net-zero buildings.

Efficiency varies by product and configuration. The listed BPE systems use direct counter-flow heat exchangers with stated thermal efficiency ranging from 70–90%+; the Plug-and-Play ERV is listed at over 90% thermal efficiency. Actual performance depends on airflow, operating conditions, installation, and system selection.

Available airflow depends on the selected product and configuration. The listed Plug-and-Play ERV includes built-in 200 CFM fans, while the Unitary ERV Systems cover 500–20,000 CFM and the Modular Energy Recovery Modules cover 200–2,250 CFM across the product line. Selection should match the building’s ventilation design.

Yes. The product information identifies HVAC system retrofits and new installations as applications. Modular units are designed to be man-portable and fit through 36-inch doors, while stackable construction and low static pressure operation can support integration where access, equipment handling, or existing system constraints influence the installation.
