This replacement project showcases an XeteX custom outdoor Air Handling Unit specifically designed for a prestigious Fortune 100 corporate headquarters. It offers unparalleled energy efficiency, reliable performance, and enhanced indoor air quality.
A Remarkable Retrofit and Replacement Custom Air Handler
XeteX is North America’s leading custom air handling systems manufacturer for industrial and commercial applications. Heating, air conditioning, and ventilation was design in one unit with six split sections. This made rigging and transportability more efficient for installation.
In 2021, XeteX won the bid to design and deliver an energy efficient custom air handling unit to replace a 30-year-old unit. Because of its quality performance, XeteX was chosen to replace a second similar AHU in 2023.
XeteX custom designed the AHU with energy efficiency products while retro fitting the new system into the existing footprint and utilizing the existing mechanicals. Not easy to do, but XeteX successfully delivered another high quality custom air handling unit to perform for decades to come.

The AHU includes several components that contribute to promoting the functionality in providing a comfortable and healthy indoor environment. Six return fans ensure efficient air circulation within the system. The 2" MERV 8 OA filter helps to remove airborne particles and improve indoor air quality. The DX evap. cooling coil plays a crucial role in the cooling process, while the UV lights help to eliminate bacteria and viruses. The inclusion of a humidifier manifold ensures optimal humidity levels.
The AHU also incorporates a gas-fired steam generator, which provides additional heating capacity when required. It features eight supply fans, ensuring a consistent and regulated airflow throughout the system. The indirect fired gas burner further enhances the heating capabilities of the system, making it suitable for year-round operation. Finally, the vestibule provides a dedicated space for compressors and electrical panels, ensuring easy access and maintenance.
