AAON - Model RN Series -Rooftop Units
FromAAON, Inc.
AAON RN Series Rooftop Units continue to lead the packaged rooftop equipment industry in performance and serviceability. Double wall rigid polyurethane foam insulated cabinet construction and direct drive backward curved plenum fans allow RN series units to have quiet, energy efficient airflow with high static pressure capabilities. RN Series Units also feature lockable hinged doors which provide service access to all sections of the unit.

Applications
- Air-cooled condenser or air-source heat pump packaged DX rooftop units, 6-140 tons.
- Water-cooled condenser, water-source heat pump, or geothermal heat pump configurations.
- Horizontal configuration is available for RQ Series units (2-6 tons) and RN Series units (11, 13, 16-30 tons), providing a solution for applications that require horizontal ductwork; it does not require special horizontal supply/return curbs.
- Chilled water or non-compressorized DX air handling units, 1,800-42,000 cfm.
- Make up air capability, up to 100% outside air, to meet ventilation requirements.
- High performance hot water, steam, electric, and gas heating.
- Dual Two-Stage R-410A scroll compressors for improved part load efficiency.
- Variable capacity R-410A scroll compressors (10-100%) for load matching cooling and improved part load efficiency.
- Variable speed R-410A scroll compressors for load matching cooling and high part load efficiency.
- Two-inch double wall rigid polyurethane foam panel cabinet construction has a thermal resistance of R-13 or greater, which exceeds the R-value of a cabinet with four-inch thick fiberglass construction. Panels include a thermal break, with no metal contact from inside to outside, to prevent heat transfer through the panel and prevent condensation on the outside of the cabinet. The inner wall protects the insulation from moisture damage, prevents microbial growth, and is easy to clean. This type of construction also makes the cabinet more rigid and resistant to damage, provides increased sound dampening, and reduces air leakage and infiltration.
- Access doors with full length stainless steel piano hinges and quarter turn, zinc cast, lockable handles provide improved reliability over single point hinges and plastic or sheet metal handles, and make the unit easily serviceable.
- Corrosion resistant exterior polyurethane paint exceeds a 2,500 hour salt spray test - over 5 times the industry standard of 500 hours.
- Double sloped stainless steel drain pans eliminate standing water which can support microbial growth and stainless steel construction prevents corrosion that could lead to water leaks and contaminants in the air stream.
- Direct drive backward curved plenum supply fans with rubber isolation mounts are more energy efficient, quieter, and require less maintenance than belt driven fans.
- VFD controlled supply, exhaust, and return fans for precise airflow control, building pressure control, and reduced power consumption.
- Labeled electrical components and color-coded wiring match the unit specific color-coded wiring diagram which is laminated and permanently affixed inside the control compartment.
- Factory provided or customer provided controller can be selected to meet existing or new building control architecture.
- Unit controls and compressors are contained within compartment isolated from the air stream for ease of service and quiet operation.
- Run test report, color-coded wiring diagram, and Installation, Operation and Maintenance manual with startup form is included in control access compartment of every unit.
- Multiple methods of humidity control including: High Capacity Cooling Coils, Return Air Bypass, Mixed Air Bypass, and Modulating Humidity Control which provides energy efficient dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems.
- RN Series Horizontal Configuration units are available with high efficiency final filtration.
- Modulating gas heat and SCR electric heat provide energy efficient, consistent supply air temperature heating and improved occupancy comfort.
- Factory installed, sensible or enthalpy, gear driven economizer allows for free cooling.
- Multiple high efficiency filtration options, with up to a MERV 14 efficiency rating.
- Factory installed total and sensible AAONAIRE® energy recovery wheels save cooling and heating dollars.
- Polymer e-coated coils are available to extend the life of the coils and protect them in corrosive environments.
- Interior corrosion protection option protects interior components of the unit in corrosive environments.
