Commercial ERV/HRV has bigger airflow type than residential ones, widely used in large commercial buildings and industrial applications, such as office buildings, hotel, theater, Hospitals, labs, confinement center, school, bank, etc.
It's also balanced ventilation system which use both an exhaust air blower and a supply fan that does not pressurize a building. Stale room air is exhausted and fresh outdoor air is brought into the structure. And there is air-to-air heat exchanger that is designed to transfer heat and sometimes moisture between two air streams. They improve the indoor air quality and reduce the load on air handling units to be more energy saving and efficient.
In these buildings, ventilation and fresh air are the key factor to consider when designing. Thanks to our commercial energy recovery ventilator, continuous fresh air will be introduced into the indoor area with lower cost.
