Alpha Class
Push the Limits with Alpha Class – Clean, Efficient Comfort Redefined.
RQ Series
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.
Capacity:

Quality
- Two-inch double wall rigid polyurethane foam panel cabinet construction has a thermal resistance of R-13 or greater. 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
- Five year non-prorated compressor warranty
- 15 year non-prorated aluminized steel gas heat exchanger warranty
- 25 year non-prorated stainless steel gas heat exchanger warranty
Features & Options
Features
- Direct drive backward curved plenum supply fans with belly band mounts are more energy-efficient, quieter, and require less maintenance than belt driven fans
- Factory installed, sensible or enthalpy controlled, AMCA Certified Class 2 low leakage gear driven economizer dampers allow for free cooling
- 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
- Modulating gas heat and SCR electric heat provide energy-efficient, consistent supply air temperature heating and improved occupancy comfort
- Multiple high-efficiency filtration options, with up to a MERV 14 efficiency rating
- 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
Options
- Two-Step staged, Variable Capacity, and Variable Speed R-454B scroll compressors for cooling and ASHP mode of operation
- Factory-installed total and sensible AAONAIRE® energy recovery wheels and fixed plate heat exchangers 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 (Electronically Commutated Motor) driven condenser fans for head pressure control, reduced power consumption and lower sound levels at off-design RQ ambient conditions
- VFD (Variable Frequency Drive) controlled or ECM driven supply and exhaust fans for precise airflow control, building pressure control, and reduced power consumption
