    VLT® Micro Drives help Vermont small businesses boost efficiency for rooftop HVAC

    VFDs are used for a wide range of motors, not just RTU fan motors. Danfoss was able to pre-program the VLT® Micro Drive specifically for RTU applications and offer it to contractors. Because the programming work is done upfront, the contractor simply mounts the drive inside the RTU, wires it up, and enters the nameplate installation. Most mechanical contractors can do the job in about half a day.
