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

Applications
- Air-cooled condenser packaged DX rooftop unit, from 2 - 6 tons.
- Water-source heat pump or geothermal heat pump configurations.
- Chilled water or non-compressorized DX air handling units, 400-3,600 cfm.
- Makeup air capability, up to 100% outside air, to meet ventilation requirements.
- High-performance hot water, steam, electric, and gas heating.
- Variable-capacity and two-step R-410A scroll compressors for load matching cooling and improved 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 lockable handles provide improved reliability over single point hinges, and make the unit easily serviceable.
- Corrosion-resistant exterior polyurethane paint exceeds a 2,500 hour salt spray test.
- 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.
- Microchannel condenser coils are more efficient, lighter, and use less refrigerant than traditional fin and tube condenser coils.
- 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 or ECM driven supply and exhaust 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.
- Variable capacity and two-step R-410A scroll compressors for load matching cooling and improved part-load efficiency.
- Multiple methods of humidity control including: High Capacity Cooling Coils and Modulating Hot Gas Reheat Humidity Control which provides energy-efficient dehumidification, even with low sensible heat loads, without the temperature swings common with on/off reheat systems.
- 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.
- ECM driven condenser fans for head pressure control, reduced power consumption and lower sound levels at off-design RQ ambient conditions.
