Smaller Cabinet Size with Lasting Toughness and Durability.
The smaller, more compact design makes installation easier without sacrificing the lasting durability you expect from Bryant. For the strength and stability needed to withstand the strain of rooftop placement by crane, these packaged systems are built with a commercial-grade, roll-formed baserail.

is the result of Bryant’s Turbo-TubularTM heat exchanger. This heat exchanger and induced draft (negative pressure) combustion system allows hot gases to make multiple passes across the supply air, thus optimizing heat transfer.

Electric Cooling.
Cooling efficiency for both the Model 559F and the Model 579F is maximized through dual circuits and computer-assisted balancing of the compressors, condenser and evaporator coils. To ensure lasting reliability, the dual scroll compressors are equipped with over-current and over-temperature protection. And, the dual TXV metering devices provide precision refrigerant control to optimize performance while preventing slugging and flood-back. And, you can choose greater cooling comfort through improved humidity control with the addition of a Bryant Thermidistat Control accessory and the factory-installed Perfect Humidity Dehumidification Package.

Gas Heating.
If your building requires gas heating in addition to cooling, the Model 579F is the right choice for you. One of the keys to the efficiency and lasting operation of this model is our Turbo-TubularTM heat exchanger. This heat exchanger saves gas by maximizing heat transfer and resists corrosion for years with our AlumagardTM coating. For simple troubleshooting, fault notification and system status, our integrated gas control board is equipped with an LED display.

Designed for Easier Installation and Enhanced Flexibility.
Designed for installation with standard roof curb sizes, the Model 559F and Model 579F packaged systems allow the contractor to order and install the roof curb before size requirements are finalized. The roll-formed baserail design features forklift slots and rigging holes for easy maneuvering during transport while providing strength and stability for rooftop placement by crane. Shipped in the vertical discharge airflow configuration, these units can be field-converted quickly and easily for horizontal applications using the supply/return adapter assembly.
