The WaterFurnace Energy Recovery DOAS integrates with a full system to efficiently clean air and transfer heat and moisture. Not only does the DOAS bring fresh outdoor air inside the building, it also has the added bonus of helping maintain temperature and humidity levels by transferring the properties of the conditioned air to the air that’s being brought in. That results in tremendous energy savings. Instead of being on the rooftop like most Dedicated Outdoor Air System, the Versatec DOAS is an easily accessible interior unit. That increases life expectancy, easier to maintain, and eliminates costs associated with a rooftop installation.
