CB Series

AAON CB Series Condensers & Condensing Units are engineered to be energy efficient, long lasting, and easy to install. standard features include variable speed ecm driven condenser fans, two step compressors, and a continuous fin condenser coil with louvered coil guard. CB Series Condensing Units can be used in residential and commercial application, matching with aaon air handling units.

Applications

•	Air-cooled condensing unit or a remote air-cooled condenser, from 2-5 tons or 24-60 MBH.
•	Available as an air-source, water-source or geothermal heat pump.
•	Two step scroll compressor, 67% and 100% capacity, includes rubber isolation mounts to minimize vibration.
•	Variable capacity scroll compressor (10-100%) for load matching cooling and improved part load efficiency.

Construction

•	Wrap-around, single row condenser coil has no additional rows to trap dirt and debris between and is easier to clean than units with multi-row coils.
•	Louvered condenser coil guards protect the coil from damage and debris.
•	Corrosion resistant polyurethane paint exceeds a 1,000 hour salt spray test - twice the industry standard of 500 hours.
•	Refrigerant circuit contains automatic low pressure and manual reset high pressure safety cut-outs, suction and liquid line Schrader valves, a full charge of refrigerant for up to 25 feet of line set, and a factory provided liquid line filter drier.

Fans and Blowers

•	ECM driven condenser fan provides precise airflow control and reduced power consumption while matching each capacity step of the compressor.

Control

•	Labeled electrical components and color-coded wiring match the unit specific color-coded wiring diagram which is inside the control compartment.
•	Unit controls are contained within single compartment isolated from the air stream for ease of service and quiet operation.
•	Factory run test report, wiring diagram, and Installation, Operation, and Maintenance manual with startup form are provided in the control compartment of every unit.
•	Optional 24 VAC control circuit transformer to prevent exceeding the capacity of the air handler’s control circuit transformer.

Features and Options

•	Split system modulating humidity control is available to provide energy efficient dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems.
•	High density foam compressor sound suppression blanket to reduce radiated noise.
•	Polymer e-coated coils are available to extend the life of the coils and protect them in corrosive environments.
•	Low ambient fan cycling allows operation down to 35°F for facilities that require mechanical cooling at lower ambient temperatures.
