Best quality components for any RTU application

The constant innovation in rooftop unit (RTU) design is driven by new demands for higher energy efficiency and local regulations. Lower operating costs or standards such as LEED, include requirements for new, low GWP refrigerants, and create the need for products to support these changes in RTU designs.

Danfoss has extensive experience in solutions for RTUs, used in commercial air conditioning systems. Our range of components comprises some of the most reliable and best quality components for any RTU application to meet the specific demands of energy efficiency, reliability and cost.

Our wide product portfolio makes selections for complete units easy and efficient. We invite you to browse through our offering from metering devices to compressors, inverter technology, control valves and filter driers and the like.

    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.
