Features and Benefits


Daikin Packaged Rooftop Units (RTUs) are designed with fast and easy installation in mind for both new construction and retrofit. Installers can benefit from our field installed options such as roof curbs for new constructions.

Cabinet Construction

Daikin packaged rooftop units are made with high quality galvanized steel with a powder-paint finish to provide higher corrosion resistance.


High performance, low noise scroll compressors adjust the speed to match the required total cooling and heating load for efficient part load control.

Supply Fan

Indoor fan motors are belt drive as standard to provide easy in the field belt and pulley adjustment for airflow control.


All units use large face area outdoor coils. These coils are constructed with seamless copper tubes, mechanically bonded into aluminum plate-type fins with full drawn collars to completely cover the tubes for high operating efficiencies.

Controls and Wiring

Packaged rooftop units come equipped with a well-organized, large, easy to use, weather proof internal control box with easy access, for a better user experience.


Unit provides a draw-through filter section as standard for better air quality and longer lasting component maintenance.

Heating Section

Wide range of natural gas and electric heat selections effectively handle most comfort heating demand from morning warm-up control to full heat, all available with Daikin’s Wrinkle Bend heat exchanger technology.

Gas Furnace

ETL certified heating modules provide a custom match to specific design requirement.


Units are completely wired and tested at the factory to provide faster commissioning and start-up.
