Johnson Controls introduces York® Predator® split systems, a new line of environmentally friendly, EPAct 2010-compliant and economical commercial split cooling and heat pump systems.

Available in 7.5- to 20-ton capacities, York Predator systems use R-410A refrigerant and feature a compact design based on the robust and reliable platform of the Predator line of packaged rooftop products. MicroChannel condenser coils on the cooling units provide superior heat transfer while using less refrigerant, and scroll compressors ensure both high efficiency and reliability.

All models in the new line include Simplicity® microprocessor controls, engineered for easy set-up and programming, to provide alarm monitoring. Single or dual (two- or four-pipe) refrigerant circuits provide redundancy and a variety of application choices, including one outdoor unit matched with two indoor units.

Vertical discharge condenser fans direct sound upward and away from any surrounding structures for quiet system operation. In addition, scroll compressors are mounted on rubber isolators to reduce the transmission of vibrations.

Predator air handlers feature a number of options, including factory-installed standard and oversized motors, techni-coated indoor coils for corrosion protection and a standard two-inch filter rack that can easily be field-converted to accept four-inch filters. Designed to operate both cooling condensers and heat pumps, the new air handlers also include adjustable thermostatic expansion valves, liquid line solenoids for capacity reduction and an adjustable motor sheave to allow airflow flexibility in the field.

Units in the new Predator line come completely assembled, piped and wired at the factory to provide one-piece shipment and rigging. Each unit is pressurized with a holding charge of R-410A refrigerant for storage and/or shipping.
