Energy Recovery Units (ERUs)

Energy recovery in HVAC captures useful heating or cooling energy from exhaust air before it leaves a building. The recovered energy preconditions incoming outdoor air, reducing the load on heating and cooling equipment. BPE systems use air-to-air heat exchangers to support fresh-air ventilation, lower energy consumption, and improve overall building performance.

Energy Recovery Units are used in residential homes, multifamily buildings, offices, light commercial spaces, industrial facilities, machine shops, and dedicated ventilation systems. They can support HVAC retrofits, new installations, fresh make-up air, exhaust-air heat recovery, and high-performance projects such as Energy Star, Passive House, and net-zero buildings.

BPE offers plug-and-play ERVs, modular energy recovery modules, and stackable unitary ERV systems. Configurations include compact residential equipment, modular systems for commercial applications, and larger systems for industrial or commercial ventilation. Product options vary by airflow range, installation format, footprint, fan arrangement, and HVAC integration requirements.

Efficiency varies by product and configuration. The listed systems use direct counter-flow heat exchangers with thermal efficiency ranging from 70% to over 90%+. The plug-and-play ERV is listed with over 90% thermal efficiency. Actual performance depends on airflow, operating conditions, controls, installation, and system selection.

Yes. BPE products are identified for HVAC system retrofits as well as new installations. Modular and unitary designs can support fresh-air intake and exhaust-air heat recovery, while compact plug-and-play ERVs suit dedicated ventilation applications. Final selection should consider available space, airflow requirements, static pressure, ductwork, electrical service, filtration, and control integration.

ERUs introduce outdoor air while exhausting stale indoor air, helping support continuous ventilation and improved indoor air quality. The listed plug-and-play ERV includes an integral MERV 8 filter for fresh and exhaust air. Proper design and maintenance remain important for filtration performance, airflow balance, contaminant control, and occupant comfort.
