Features and Benefits


Daikin Packaged units are designed with an easier and faster installation in mind for both new construction and retrofit. Our packaged rooftop units are built to be a direct replacement for most rooftop units on the field without the need of a curb adapter, to be able to replace the unit in a shorter time and at a lower expense.

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 to match the required total load for efficient part load control.

Supply Fan

The direct-drive with airfoil single width, single inlet (SWSI) Class II construction supply fan with aluminum fan +blades provides efficient and quiet operation at wide ranging static pressure and air flow requirements.


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 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.
