The Raytheon AUR is a 70,000 square foot facility located on Redstone Arsenal where two different types of missiles will be assembled and tested. The HVAC equipment includes heating hot water boilers, air cooled chillers, pumps, and custom air handling units that are all housed in an outdoor mechanical yard. All the equipment had to be specially modified to withstand the weather in the summer months, as well as the cold winter months. There is also a house cleaning vacuum system located throughout the facility with outlets staged so every part of the facility can be reached for cleaning. The large ductwork in the assembly area is installed through the massive steel truss supports. Other systems installed include a clean dry air, gaseous nitrogen, and RO water system.
