Commercial HRVs / ERVs

Fantech’s light commercial heat and energy recovery units can be used in various applications from swimming pools and small offices to larger commercial applications. Common to all, each and every system and component has been developed with energy savings in mind. Heat and Energy exchangers, motors and fan units have all undergone extensive testing, both in the laboratory and in the field, in order to exceed current and future demands for low energy consumption.

Our products are designed for a long service life, which leads to the least amount of environmental impact over time. And, to ensure easy installation, many of our units feature control systems that are enabled for plug-and-play, i.e. simple, stress free start-up.


HRVs are recommended when the indoor relative humidity will be higher due to the presence of showers, spas, saunas and hot tubs. High occupancy density often results in higher indoor humidity, so HRV are also better in those applications. 

ERVs are great in warm and humid climates since they may reduce the amount of outdoor humidity that enters the building through the ventilation air if the building is air conditioned and maintained at a normal indoor relative humidity and temperature. In cold climates, an ERV will not dry the indoor air as much as an HRV since a portion of the exhausted air’s humidity is recovered back into the fresh air supply.

How much air do I need?

The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) has developed guidelines to evaluate the minimum ventilation needs. Below are two simplified tables from the standards showing ventilation rates for different applications. Note that the full standards and/or a local building code should be reviewed to make the proper selection.

For a commercial application refer to ASHRAE Standard 62.1.
