Large air handlers can be addressed 1 one or 2 areas, either at the evaporative coil or in the supply duct. When installing the lamps at the coil, it can be done with just a few lamps for coil irradiation (killing mold and bacteria on the coil) or full air stream sterilization by using more lamps. Alternatively, coil irradiation can be done at the coil and the air stream sterilization could be done in a duct (if accessible)
