Custom Outdoor Energy Recovery Unit for a Casino

This XeteX project features five large outdoor energy recovery units to help tackle this casino’s ventilation challenges.


Casinos face the challenge of introducing large amounts of outside air while ensuring filtered and temperature-controlled environments to provide a welcoming and comfortable environment for patrons.

Conditioning the outside air is the most energy intensive portion of an HVAC system. To help reduce energy consumption, each unit was equipped with an AiRotor 3A energy recovery wheel which offers up to 72% energy recovery effectiveness.

Additionally, the energy wheel was specially coated with an acrylic polymer to reduce exhaust air contaminants from “sticking” to the face of wheel. This will ensure long-lasting wheel performance and continued unit energy savings.
