This Xetex featured project is an indoor Dedicated Outdoor Air System (DOAS) with an enthalpy energy recovery wheel designed specifically for a K-12 educational facility. This innovative system ensures optimal indoor air quality, energy efficiency, quiet operation, and cooling comfort to encourage a quality learning environment for students.

The DOAS is equipped with an 3A AIRotor Enthalpy Energy Recovery Wheel, which allows for efficient heat and moisture removal between the incoming and outgoing air streams. This process helps to reduce the load on the cooling and heating systems, resulting in significant energy savings.

The DOAS is equipped with an evaporator coil and a HW (Hot Water) coil, allowing for efficient heat transfer, precise temperature control and facilitates the exchange of heat and moisture between the incoming and outgoing air streams.

For cooling purposes, the system utilizes a remote DX (Direct Expansion) condensing unit with a cooling capacity of 70 tons.
